Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt. Which statement is correct? 12/16 white: 3/16 green: 1/16 yellowA) At least one copy of both dominant alleles results in white; at least one copy of one of the dominant alleles also results in white, but at least one copy of the other dominant allele produces green; and the absence of either dominant allele produces yellow.B) If both dominant alleles are present, the result is green. At least one copy of one specific dominant allele is required for yellow. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.C) At least one copy of each dominant allele results in white, at least one copy of either dominant allele produces green, and the absence of either dominant allele produces yellow.

In lab this week we observed a frog dissection. I love the frog dissection because many of the frog's organs look very similar to a human's organs! Let's think back to the frog's digestive system. The frog's digestive system is very similar to a human's digestive system, but not exactly the same. For your post, imagine that a frog eats a fly. Write the path the fly would take through the frog's digestive system, starting with the mouth and ending with the cloacal opening.

Answers

Answer:

Mouth, esophagus, stomach, small intestine and large intestine.

Explanation:

Digestive system of frog starts in the mouth and ends at the cloaca which means the enzymes present in the mouth start break down of food eaten by the frog. After food enters the mouth, it goes to the esophagus and then to the stomach. From there, it forwarded to the small intestine, where food becomes broken down and all nutrients extracted from it. it then goes to the  large intestine, which absorbs remaining water.

what's the best way to study for a final exam in 2 days??​

Answers

So people learn very differently and there is not a correct way to study. If you are a memory person then I would do flash cards. If you are a sports type person then I would say study while bouncing a ball. If your teacher lets you have music make a playlist and study while listening to it. Also if you make up rhymes or saying for things you are more likely to remember them. If you are artistic then draw pictures to help you remember certain things. Also peppermint helps you remember things. Lastly study before you go to bed and get at least 8 hours of sleep before the test. This will put what you studied into long term memory instead of short term. Lastly don’t stress to much because it’s harder to remember what you studied when stressed.

Why do you think ANIMAL CELLS are able to survive without the types of cell walls that are present in nearly every other group of organisms? Provide 3 answers.

Answers

Answer:

They survive because these cells need a high permeability to be able to maintain the internal cellular balance in relation to the external environment that surrounds them, and this is due to their high energy demand, their multi-complex and multiple functions, and the capacity for constant homeostasis with the environment. that surrounds them.

Explanation:

In addition, some cells need to transmit signals, second messengers or even to fulfill a function to exchange compounds for their transmembrane, this is what makes the human system together with other systems of other animals is extremely open and is in constant energetic exchange, in addition to Unlike plant cells, plant cells are under an autonomous regime, they do not need to take energy from the environment but they manufacture it themselves, and it fulfills a great function that is to provide structure and support, the wall they have is what gives it the ability to fulfill these two functions.

how do mutations and natural selection lead to resistant populations of bacteria

Answers

Answer:

Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.

the answer would be true

Today, the word "bureaucracy" is used to refer to any organization that has many departments, which is a false statement as bureaucracy is related to government administration.

What is the significance of the bureaucracy?

The importance of bureaucracy includes making sure that governmental tasks are carried out effectively and efficiently by skilled professionals who are authorities in their fields and are capable of handling their tasks with a high degree of competence. They make sure that government policies are applied consistently and fairly. They are tasked with providing information and support to regular individuals who require it since they are a crucial part of public administration and governance.

Explanation:

If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.

Answers

Answer:

10 chromosomes

20 chromatids

Explanation:

Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.

Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.

Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much will the action potential rate increase if the stimulus intensity increases by 100?

Answers

Answer:

The action potential rate will be doubled

Explanation:

The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.

For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000

Log₁₀1000 = 3 since 10³ = 1000

Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:

Log₁₀100 = 2

Therefore, the action potential rate will be doubled

The postulates of a cell theory are as follows:-

All the organism is made up of cellThe structure and the functional unit of life is the cell.All the pre-existing cell is made up of old cell.

The limits of the cell division are cancer cells. The cancer cell does not stop after a limit. It divides continuously and forms a tumor.
