Answer:
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
Answer:
A. Air
Explanation:
Abiotic factors are things that are not living.
Air can be found in a rain forest ecosystem, as it can be found in all ecosystems, but it is not living.
On the other hand, algae, flowers, and animals are biotic instead of abiotic because they are living things.
So, A is the correct answer.
Take for example the group of prokaryotes against eukaryotes. They may be similar in a way that they contain cells with organelles such as mitochondria, ribosomes, cytoplasm, and many more. But they may differ in the presence of a cell membrane and a nucleus. Eukaryotes have cell walls and a nucleus, while prokaryotes don't have.
Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
