when nonsister chromatids exchange genes it is called:
Answer:Chromosomal crossover, or crossing over
Explanation:
Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
The primary electron acceptor in photosystem II is __________. Group of answer choices P700 P700 P680 P680
Answer:
680
Explanation:
When the P680 special pair of photosystem II absorbs energy, it enters an excited (high-energy) state. Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin.

which hormone signals the breakdown of glycogen in the liver increasing glucose in the blood?
Answer:
The answer is glucagon
Explanation:
When the blood sugar level drops down, the glucagon hormone converts the glycogen into glucose and raises its level in the bloodstream.
Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.
Which hormone stimulates the breakdown of glycogen in the liver into glucose?Glucagon's role in the body is to prevent blood glucose levels from dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream.
How does glucagon increase blood glucose?
When your blood glucose levels trend lower or fall too low (hypoglycemia), your pancreas releases more glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

During cellular respiration, most of the ATP energy generated comes from the electron transport chain. True false question. True False
Answer:
A true
Explanation:
only 4 at is created outside the electron transport chain
but cellular respiration produces at net gain of 36 atp
thus the other 32 atp comes from the electron transport chain

Factors
Increase or Decrease
in Carrying Capacity?
Answer:
Carrying capacity, or the greatest number of people that an environment can support over time without harming or degrading it, is controlled by a few basic factors: food supply, water availability, and space.

Explanation:
why do polygenic traits show bell curves in variation
Answer: because there are multiple genes that play a role in the phenotype, and each gene could have multiple alleles. This can give a range of possible phenotypes from all the variation that's coming into play here.
if a cell is in a state in which it no longer divides then the cell is probably arrested at which stage of the cell cycle?
Answer:
Interphase
I
Explanation:
Interphase is the period of the cell cycle during which the cell is not dividing. The majority of cells are in interphase most of the time. Mitosis is the division of genetic material, during which the cell nucleus breaks down and two new, fully functional, nuclei are formed.

How does melanoma affect the functions of the skin?
How does jaundice affect the functions of the skin?
Answer:
Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.
Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.
what is prophase, meta phase and anaphase labled under?
1.Mitosis
2.DNA replication
3.Meiosis
4:Photosynthesis
Answer:
Technically Mitosis and Meiosis
Explanation:
Mitosis is the spliting of Body Cells. Mitosis goes through 4 phases that are easy to remember as PMAT. Mitosis starts with Interphase then moves to Prophase, Metaphase, Anaphase, and Telephase. These steps also occur in Meiosis. However Meiosis goes through these step twice. If you need further explaination of mitosis and meiosis I recomend the amoeba sisters.

Based on information from the cladogram and the data table shown below, which of the following best describes the evolutionary history of rabbits?
Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X
Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.
Answer:
A. They are more closely related to tigers than they are to birds.
Explanation:
Short answer: I took the test
Actual explanation:
-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.
-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.
- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.
- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.
So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))
