Yes can you tell the genotype because obviously if you can tell the genotype then there you go

Basile [38]

Answer:

I don't want to give wrong answer, but here is what ik kiddo;

Explanation:

An experimental group is the group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing.

e) Is this is a silent mutation or a missense mutation? Explain. Hint: Silent mutations have no effect on the amino acid. I RLY

Answer:

hope it helped u

plzzz mark as brainliest.

Explanation:

Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.

Mutations that cause the altered codon to produce an amino acid with similar functionality (e.g. a mutation producing leucine instead of isoleucine) are often classified as silent; if the properties of the amino acid are conserved, this mutation does not usually significantly affect protein function.

What clues could you use to help determine whether movement of oslutes through the apicl and basolateral cell membranes is passi

Setler79 [48]

Answer:

Clues that can be used to determine whether the movement of solutes through the membrane is passive or active could be the molecule size, membrane potential, and the presence/absence of membrane protein.

Explanation:

Solutes transport through the cellular membrane depends on the solute size, membrane potential, and the presence/absence of integral membrane protein.

There are two types of transport: Active and passive.

- Passive transport: It does not need energy; it is driven by a chemical potential gradient. Small molecules with no charge are transported through the membrane in a gradient favor, from a high concentration region to a low concentration region. There are two types of passive transport: By simple diffusion (small molecules pass through the membrane by themselves) and by facilitated diffusion (molecules are helped by integral membrane proteins to pass through the membrane). In facilitated diffusion, the helping protein can be a channel protein (hydrophilic pores that allow the molecule to pass with no interaction) or a carrier protein (proteins with mobile parts that suffer modification as the molecule pass to the other side).

- Active transport: It does need ATP energy to pass the molecule through the membrane, as they have to move against the electrochemical gradient. This kind of transport is always mediated by a carrier protein. These proteins join with the molecules and suffer changes as they pass the solute to the other side of the membrane. An important example of this kind of transport is the sodium-potassium bomb.
