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.

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.
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.

1. how would dr.budai refer to the new fern that contractors plan on introducing into the environment?
2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?
3. how might the building of the hotel affect the population of the new species?
Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.
Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.
Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.
The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Which table shows two steps of DNA replication?
DNA replication is a process where the polymerase enzyme adds complementary nucleotide bases in the parent DNA strand, hence option h polymerase matches adenine to thymine is correct.
What is DNA replication?The process by which a double-stranded DNA molecule is duplicated to form two identical DNA molecules is known as DNA replication.
Replication is necessary because when a cell splits, the two new daughter cells must have the same genetic information, or DNA, as the parent cell. In vitro DNA replication (DNA amplification) is also possible (artificially, outside a cell).
To begin DNA synthesis at known sequences in a template DNA molecule, DNA polymerases isolated from cells and artificial DNA primers can be utilized.
Therefore complementary base pairing of nucleotide base pairing, hence option h is correct.

at what point in meiosis do sister chromatids separate?
Answer:
anaphase II
Explanation:
This is when the string like things pull the sister chromatids and move them towards opposite poles. And then in the next step they began to separate as two different cells
at what point in meiosis do sister chromatids separate?
Answer :Anaphase
Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

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 :))
