The correct answer is - A. A mutation that causes the code for the wrong amino acid.

The missense mutation is a type of mutation that affects the amino acids of the organisms. This mutation results in a codon that codes a different amino acid rather than the one that should be coded. Because of this it causes a synthesis of a protein with altered amino acid sequence during translation. This type of mutation is basically a change in one DNA base pair that results in the substitution of one amino acid for another one.

<h2>Answer:</h2>

<u>The right choice is </u><u>(A) mutation that causes the code for the wrong amino acid.</u>

<h2>Explanation:</h2>

In cell biology during when a missense mutation occurs in a DNA molecule, it varies in one of the RNA codon sequences which are made during transcription. The difference produced in codon will then cause a different amino acid to be inserted into a protein during translation process so we can say that a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid

Answer:

The Genotype: Cc

Explanation:

On a punnet square if the dad carries the gene as a homozygous dominant trait that the would make his genotype: CC

For the mother, she would have hers as cc which would mean that the probability of her being colorblind is 1/2 so she would not be color blind

Answer:

Woman's genotype is AO

Man's genotype is BO

Explanation:

For a woman with blood group A and a man with blood group B to give birth to a child with blood group O. Their genotypes will be:

Woman's genotype is AO

Man's genotype is BO

The can have a child with blood group A, B, AB and O

1/4 will have type AB blood group;

1/4 will have AO, which is type A blood group;

1/4 will have BO, which is type B blood group;

All energy in any ecosystem starts as

ExtremeBDS [4]

I'd say heat, more specifically sunlight.

Why?

Because sun is the form of energy needed for plants to grow and live. Plants in turn are the form of energy needed for herbivores to live that later on turn out to be the form of energy needed by the carnivores. When these die, decomposers will be the ones to take advantage of the energy.

As you can see an ecosystem has already been formed: producers, secondary consumers, tertiary consumers or decomposers.

Hope it helped,

Happy homework/ study/ exam!

In a marine ecosystem, starfish prey upon the common mussel. Common mussels feed upon plankton. What is MOST likely to happen if

Kay [80]

The answer is;

The numbers of mussels would reduce

Planktons population would increase.

This is a phenomenon common in food chains where a reduction in predator population increases the prey population and vice versa. This is because the species population in a food chain/food web are interlinked and source energy from one another directly or indirectly.
