how might the biotic and abiotic features change during different seasons?
Answer:
The biotic and abiotic features change during different seasons through various factors.
Explanation:
Biotic and abiotic factors are referred to as the living and non living components of the ecosystem respectively. An example of biotic factor include plants, animals and an example of abiotic factors are water, sunlight etc.
The biotic and abiotic features change during different seasons through various factors. Biotic factors in dry season for example will lead to a decrease in abiotic factors such as rainfall and increase in abiotic factors such as sunlight while leading to a decrease in biotic factors such as plants and animals through the lack of water vital for them.
Biotic factors in wet season for example will lead to a increase in abiotic factors such as rainfall and decrease in abiotic factors such as sunlight while leading to a increase in biotic factors such as plants and animals.

A student is investigating mitosis by examining detailed pictures of the process the student wants to observe the formation of the nuclear envelope.the student should focus on pictures of which phase of mitosis
telophase
,prophase
,metaphase
,anaphase
Answer:prophase
Explanation:
Telophase, the fifth and final stage of mitosis, occurs when a parent cell's replicated genetic material is split into two identical daughter cells.
What is mitosis?Mitosis is a stage of the cell cycle during which replicated chromosomes are separated into two new nuclei. Mitosis results in the formation of genetically identical cells with the same number of chromosomes. As a result, mitosis exists as also referred to as equational division. Mitosis is the division of a single cell into two identical daughter cells (cell division). Mitosis is a nuclear division process that occurs in eukaryotic cells when a parent cell divides to produce two identical daughter cells. Mitosis is the separation of the duplicated genetic material carried in the nucleus during cell division.To learn more about mitosis, refer to:

PLEASE HELP ME WITH 10 and 11!! :(
Answer:
Please find the answers to numbers 10 and 11 of the attached image below.
Explanation:
10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:
A) PROPHASE:
- the supercoiled chromosomes known as chromatin begins to condense making it visible.
- spindle begins to emerge from the centrosome organelle.
- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.
B) METAPHASE:
- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.
C) ANAPHASE:
- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.
D) TELOPHASE:
- Chromosomes at opposite poles begin to decondense into chromatin.
- The nuclear envelope reforms around the chromosomes
11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.
what is the correct equation for photosynthesis?
Answer:
6CO2 + 6H20 ⇒ C6H12O6 + 6O2
Explanation:
Carbon Dioxide + Water ⇒ Glucose + Oxygen
Photosynthesis is the process through which plants prepare their own food in the presence of sunlight in the chloroplast of the cell.
What is Photosynthesis?Photosynthesis is the process of transformation of energy from solar energy (radiation) into chemical energy. The chemical energy is present in the form of chemical bonds present in the glucose molecule (carbohydrate).
The process of photosynthesis is commonly written as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This means that the reactants in the process are six molecules of carbon dioxide and six water molecules, are converted by the light energy (radiation) captured by chlorophyll into a sugar molecule (carbohydrate) and six oxygen molecules, as the products.

What do these two changes have in common? snowflakes forming in a cloud and cellular respiration
Answer:
The product of both reaction is water.
Explanation:
Both snowflakes forming in a cloud and cellular respiration have similarity of water means both releases or produce water in the end of the process. The snowflakes is made of water molecules which is present in solid state while on the other hand, when glucose is broken down in the presence of oxygen during the process of respiration, it produces carbondioxide gas and water so the product of both reaction is water.

How are the endoplasmic reticulum and Golgi apparatus
similar?
Both contain their own kind of DNA.
O Both are made up of membranes consisting of a lipid bilayer.
O Both are involved in producing chemical energy for the cell.
O Both are found only in plant cells and not in animal cells.
Answer:
Both are made up of membranes consisting of a lipid bilayer.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
Golgi apparatus is like a packaging unit because it prepares the protein for export by chemically tagging them.
Also, the endoplasmic reticulum is like an assembly line because it is where the ribosomes perform their tasks.
Hence, the endoplasmic reticulum and Golgi apparatus are similar because both are made up of membranes consisting of a lipid bilayer.
Which organisms fix nitrogen into forms like ammonia?
Answer:
Bacteria
Explanation:
Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester
Answer:
In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.
The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.

→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.
→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.
→In this two or more blocks of different sizes are prepared for testing.
→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.
Imagine an animal cell lost half of its mitochondria. Explain how the cell would be different.
YOU WILL GET 100 POINTS.
Answer:
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...
Explanation:
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.
in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

Choose one of the water management concerns listed below and give an example of where this is happening. Please cite your source and change the heading of your post to show which concern you are discussing. Make sure to also show how this impacts the water cycle.
a. withdrawing large quantities from streams, lakes, and aquifers.
b. increasing runoff by clearing vegetation from the land.
c. altering weather patterns by clearing vegetation.
d. increasing flooding by disturbing natural flood controls.
Answer:
Water Withdrawal: it has happened in some lakes in Minnesota
Explanation:
The water cycle is influenced by seasonal-climatic fluctuations and human activity. Water withdrawal is one of the human activities that most seriously affect the amount of water in lakes and aquifers by reducing water storage, thereby altering the flow in streams, lakes and wetlands. Concerning this situation, the state of Minnesota incorporated 1- the use of a US database (State Water Use Database, SWUD) with useful water use information on withdrawals and consumptive uses and 2- an index based on the sum of permitted water withdrawal from surface and groundwater. This index estimates the use of water as a percent of the surface water runoff to define and predict the vulnerability of lakes, using data from 54 stream gages recorded from 1988-2007. The catchment scores are scaled from 0 to 100 depending on the percent of runoff used.

Which class of protozoa shows nuclear dimorphism:
Answer:
Protozoan Tetrahymena
hope it helps!
Protozoa are eukaryotic organisms that are single-celled and free-living. Paramecium and Tetrahymena are the members of the ciliated class of Protozoan showing nuclear dimorphism.
What are Protozoa?Protozoans has been defined as unicellular eukaryote that is either parasitic or free-living. Ciliate is one of the classes of Protozoans that are characterized by the presence of cilia on the outer surface of the body.
The genus Paramecium and Tetrahymena of ciliated Protozoans show nuclear dimorphism as they have two different types of nuclei in their cell. One of the nuclei is somatic and the other is germline.
This property of nuclear dimorphism is seen in the lower organism like the Protozoans that needs a micronucleus for reproduction and the other macronucleus for the functioning and regulating of the cell. This property of the Protozoans makes them different from the other eukaryotes that possess only a single nucleus in their cell.
Therefore, the ciliated class of Protozoans shows nuclear dimorphism.
