The proteins are found around the holes and help move molecules in and out of the cell.
Answer:
D
Explanation:
An enzyme called poly (A) polymerase (PAP) is part of the same protein complex that cleaves the pre-mRNA and it immediately adds a string of A nucleotides, called the poly (A) tail, to the 3′ end of the just-cleaved pre-mRNA. The poly (A) tail added protects the mRNA from degradation, aids in the exportation of the mature mRNA to the cytoplasm and helps in binding proteins involved in initiating translation.
Answer:
75% of their offsprings will be red birds, and 25% will be with birds, this is the phenotype.
The genotype will be BB, Bb, and bb.
Explanation:
he information that we have is that B is the dominant allele for red feathers in a bird, and b is the recessive allele for white feathers in a bird.
If we cross two heterozygous birds that means that both progenitors are Bb, if we draw a Punnet Square we can see that 75% of the offsprings will be red birds, and 25% will be white birds, this is the phenotype, which is what we can physically see of the genes.
The genotypes will be BB, Bb, and bb, these are the different combinations of genes that can happen, and that explains why a bird is red or white, which is due to the dominance of one allele over the other.
<u> ║ B ║ b ║</u>
<u>B║ BB ║Bb ║</u>
<u>b║ bB ║ bb ║</u>
Penguins are a species of flightless birds and they have heavy and dense bones, which is an advantage because of which they are more efficient hunters in the water. The correct option among all the options that are given in the question is the third option. The heavier bones of the penguins gives them advantage over the natural buoyancy of water.
