Answer:
Plant hormones playa crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant
Explain how salinity can make water move
Answer:
Through concentration gradients and a semi-permeable membrane.
Explanation:
Imagine a semi-permeable membrane splitting a beaker into two sides which only water can pass through and salt cannot.
One side is filled with much more salty water than the other. (the saltiness, not the amount of water).
Since the salt cannot pass through the membrane, one side's salt is much more concentrated than the other.
In an effort to restore equilibrium, more water passes to the saltier side to balance out the ratio of water : salt.
Since one side has more salt, more water is needed to balance that out, and hence water moves towards the saltier side.

For which of the following problems would a crop rotation of various grains and legumes be an appropriate solution?
I. The nutrients in the soil on a farm are being depleted.
II. Over-irrigation is waterlogging the soil on a farm.
III. A particular kind of pest is infesting the soil on a farm.
II only
III only
I and II only
I and III only
Answer:
I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.

Biology books used to describe interphase as the “resting phase.” Based on what we know now, what was wrong with this term?
Answer: because in the interphase the cell still goes through changes(growth, replication of its DNA), they are just not visible by microscope. Therefore, the cell isn't resting.
7. Imagine that all nations agreed to reduce greenhouse gas emissions by half in an effort to reduce global warming. In what ways could you revise this simulation, so it accounted for the influence of this solution on arctic habitat, and on the whale and seal populations?
If all nations agreed to reduce global warming then It would be good because the seals need icy conditions. So the less global warming then the more icy habitats there will be and the seals will have more places to live.

A powerful windstorm moves through a densely populated white oak forest. The oaks in this forest have either smooth or rough bark. The storm randomly knocks down 50% of the white oak trees. The remaining oaks grow and produce seeds that germinate and fill in spaces in the forest. All of the new oaks have smooth bark. Which of these processes is described in this example?
Answer:
Secondary succession.
Explanation:
These processes is known as Secondary succession because disturbance occurs in the environment due to powerful windstorm which eliminates rough bark oak tree while no damaged happen to the smooth bark oak tree. So the next time the plants grow in the place of rough bark oak tree because rough bark oak tree can't withstand in that type of environmental condition and all population is available of smooth bark oak tree due to their survival mechanism.

if a prey evolves to increase its defenses, its predator often evolves to counteract this change. a. True b. False
Answer:
a. True
Explanation:
Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.

What do you think the following do when consumed? Protein, lipid,
carbohydrate, nucleic acid.
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Carbs Provide Your Body With Energy
Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.
Functions of Lipids in the Body: Storing Energy
The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue.
Protein makes up the building blocks of organs, muscles, skin, and hormones. Your body needs protein to maintain and repair tissues. Meanwhile, children need it for growth. Studies show that eating protein can also help you lose weight and belly fat while increasing your muscle mass and strength.
Once blood tonicity is negatively impacted, can the consequences be reversed?
Answer:
No.
Explanation:
Once blood tonicity is negatively impacted, the consequences can't be reversed because this tonicity permanently damaged the cell. For example, in hypotonic solution, If the water continues to move into the cell due to high solute concentration, it can damaged the cell membrane, the cell bursts and dies. But it can be reversed if the cell loses its water and become shrink in hypertonic solution and regain its original size by normalizing the water level.

Trilobites appeared approximately 521 years ago and disappeared approximately 250 million years ago. During which era did the trilobites live?
a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These
Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Adaptations that help an organism survive appear quickly. True or False? And why
Answer:
false
Explanation:
is not worth it to do that
According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.
What condition that make organism adaptive?Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.
This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.
If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.
Therefore, it is false that, Adaptations that help an organism survive appear quickly.

Explanation:
Tobacco products have been identified as mutagens. However, some tobacco users develop cancer and some do not. The reason for this apparent inconsistency is mutagens only have the capability to cause mutations if exposure lasts over 20 years some people are more predisposed to developing cancer when exposed to mutagens not all tobacco products are cancerous tobacco use only causes benign tumors that are identified as non-cancerous
Answer:
The correct statement is that some of the individuals are more predisposed to developing cancer when exposed to mutagens.
Explanation:
A single change or alternation or multiple variations within the genome of the living species is termed as a mutation, and the agent, which results in mutation is known as a mutagen. The products of tobacco are considered as mutagens. It is witnessed that some of the individuals who smoke develop cancer, while some do not. It is generally because some of the individuals are more predisposed to developing cancer when getting exposed to mutagens.
When an individual is more likely to develop cancer in his or her entire life because of certain genetic and other factors is termed as cancer predisposition. A genetic susceptibility also known as a genetic predisposition can be illustrated as the likelihood of developing a specific disease based on the individual's genetic makeup.
The individuals who develop cancer generally have family members who exhibited certain kinds of cancer and thus they have greater chances of getting the disease too. This is the reason that the predisposed individuals to cancer have a greater chance of developing cancer when they encounter mutagens and this is the prime reason to illustrate the fact that some of the users develop cancer, while others do not.

NEED THIS ASAP!!!! Define: Meiosis, Sister chromosomes, homologous chromosomes
Answer:
meiosis- a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
sister chromosomes- A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere.
homologous chromosomes- Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source. Each parent provides the same 23 chromosomes, which encode the same genes.
Answer:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number of chromosome
A sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad
homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.
Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA. Segments of DNA in specific patterns are called genes. You will find the chromosomes and genetic material in the nucleus of a cell.

Which process can occur in both mitosis and meiosis?
A. Crossing over
B. Gene mutation
C. Independent assortment
D. Fertilization
Answer:
B. Gene mutation
Explanation:
Stable changes in the DNA strand that are capable of being inherited are known as mutations.
The truly transcendent mutations for the offspring are those that are present or occur in germ cells (ovules and sperm).
The mutations that occur than can lead to small changes, large changes (causing disease: pathogenic mutations), or be silent.
Mitosis and meiosis can both be influenced by mutation of genes.
Gene mutation refers to a change to the DNA sequence of organisms. Mutation can be of different kinds, including deletion, substitution, or insertion of base sequence into genes.
Gene mutation can happen during, before, or even after meiosis and mitosis.
