One of the changes in development and specialization that did not happen in primitive mammals was the increase in stomach capacity. The specialization of teeth and the lower jaw are two important modifications of the primitive mammals. Also an increase in size and brain capacity are two crucial modifications of the early mammals.
Answer:
d: incomplete dominance
Explanation:
incomplete dominance is inheritance in which one allele for a specific trait is not completely expressed over its paired allele. this results in a third phenotype in which the physical trait is a combination of both alleles.
Answer:
Option (A).
Explanation:
Facilitated diffusion may be defined as the process of movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.
Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.
Thus, the mismatched pair is option (A).
The answer is D. A turtle suns itself on a rock during a cool day
Answer:
100%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.
According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).
Therefore, 100% of the offsprings will be white flowered.
