Answer:
No, because it would lead to chromosome mosaicism
Explanation:
Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.
what is the difference between mitosis and meiosis?
Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

plz tell me the truth
Answer:
The Brain
In the brain, the cerebrum is the largest part; it controls voluntary movement (actions you choose to do), sensory processing (vision, hearing, smell, taste, touch), speech, memory, intelligence, and emotion. The cerebrum allows you to move your muscles and know what to do when you're playing. Next, the cerebellum helps regulate motor control, coordination, and balance. The cerebellum lets you play your favorite sport since it detects shifts in balance when you're moving then sends signals to your body so it can adjust and move smoothly. The brain stem has several necessary functions: however, the medulla oblongata, which connects the brain and spinal cord, best helps you play sports since it executes a critical role in regulating involuntary functions, including respiration (breathing), heart rate, blood flow/pressure, and digestion. It is essential when exercising since it controls your heart to pump blood and deliver oxygen throughout your body; respiration provides the energy you need when playing sports and oxygen to your heart.
Neurons
However, we can go into further analysis, as three types of neurons transmit information throughout your body: sensory neurons, interneurons, and motor neurons. Sensory and motor neurons are located in the PNS (Peripheral Nervous System), while the CNS (Central Nervous System) holds the interneurons.
When you react to something, your body decides what it should do by sending impulses throughout the body.
Sensory Neurons
First, sensory neurons convey the information from the sensory organs (PNS) into the CNS.
Interneurons
The interneurons receive the impulses from sensory neurons in the CNS then relay the brain's response to motor neurons.
Motor Neurons
Finally, motor neurons transport impulses from the spinal cord (CNS) to the muscles or glands in your body.

What needs to change so that only the green solutes diffuse across the membrane?
What need to be changed is ; The use of selectively/semi-permeable membrane
To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).
The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.
Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

Nonnative species can cause serious problems with marine ecosystem biodiversity. The graph shows a summary of the different methods by which invasive species reach new locations based on United States Geological Survey data as of 2016. Based on this information, what recommendation could be made to reduce introductions?
A- Methods should be put in place to reduce the ability of species from escaping from captivity and establishing themselves in new locations.
B- People should take extra care when setting up a home fish tank to be certain that all organisms in it will be properly maintained so that the animals remain healthy and diseases are not spread.
C- Science should more closely study the genetics of the different organisms used to prevent mixing of DNA.
D- Ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.
Answer: D
Explanation: 20% of invasive species are introduced by Shipping so checking the ballast tanks in cargo ships would help the most I think
To reduce introductions of Non-native species, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and also check for unintended cargo.
What are non-native species?Non-native species are also called invasive species. They are called so as they are foreign or not indigenous to a particular ecosystem and have been introduced to the said ecosystem by some unnatural methods.
These species show a high capacity for adaptation to their new environment. They quickly multiply and reproduce and therefore increase in population.
This sudden and unnatural increase in their population soon after they are introduced to a new environment will greatly affect the ecosystem of the new environment. The new species will compete with the native organisms of that environment for resources. This may cause the native flora or fauna to become endangered or even extinct.
The accidental introduction of invasive species happens quite often and causes a lot of problems. In a marine ecosystem, it happens a lot due to the ships that travel through a variety of marine regions.
So, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.
Therefore, the correct option is D.

How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.
Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. (glucose + oxygen -> carbon dioxide + water). Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Construct at least two possible hypothesis for the students experiment
Answer:The student's observations before he starts his experiment are that his tomato plants grew faster and taller with his artificial fertilizer rather than without any fertilizer at all.

Why don’t mosses grow very tall?
They need energy to make food, which they get by being close to the ground.
They don’t have roots, so they must be near water.
They need to send out spores via water.
They have seeds that need to roll away.
Answer:
Hello~
Llamalover here!
Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can't grow very tall.
So, your answer is They need to send out spores via water. I believe

What is the purpose of a control in this experiment?
Question 9 options:
The control is the tube that only has milk in it.
The control is the one tube that we know will show milk digestion.
The control is the one tube that we know will not show milk digestion.
The control is the only one the scientist changes.
Answer:
I can't definitively answer this because I don't know the experiment, but I can help.
Explanation:
The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.
Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.
If I were to blindly guess I would say the top option seems like the most likely answer.

Fernanda is feeling sick and goes to the
doctor. Upon taking a blood sample, the
doctor observes that Fernanda's cells
contain a pathogen that seems to be made
of small cells with no nucleus. What type of
infection does Fernanda have?
bacterial
fungal
none of the above
viral
Answer:
bacterial
Explanation:
A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.
According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.
Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.
