Essential amino acids refer to the eight amino acids the adult body needs, which they cannot be synthesized correctly or at all.
The essential amino acids must be obtained from food such as proteins (meats, seafood, milk, eggs, etc).
Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Explanation:
enzymes don't change their own reaction. That's because they don't affect the free energy of reactants or the products.
Answer:
The dihybrid ratio we expect in the offspring is 9:7.
Explanation:
This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.
So in this case of complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
Answer:
B.
Explanation:
If there was a pattern are formed by the rates of evolution in different lineages then indeed the answer would be B.
Answer:
The correct answer is E) eutely
Explanation:
Nematodes are organisms with bilateral symmetry, although their organs are coiled, sometimes one of the limbs is lost and many of sedentary life tend to radial symmetry. One of the most striking characteristics of these animals is that their growth is not produced by an increase in the number of cells that compose them, but by an increase in the size of the already existing cells; in fact, in most adult tissues the number of cells is constant, a phenomenon known as eutelia.
Eutelia is the condition of an organism composed of a constant number of cells or syncytial nuclei in all adult individuals of a species, such as nematodes, it means that body growth is not carried out by increasing the number of cells but by the growth of existing cells.
