dsp733 years ago
8 0

Answer:

The DNA is a double helix or made up of two strands. The strands are separated during replication, each serving as a template to produce a complementary strand of each of the separated single strands. Therefore after replication, two double stranded DNA molecules will be present.

stiks02 [169]

Answer: The correct answer for the blanks are- 1) Dominant and 2) Blending of the trait.

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink snapdragon here) because none of the parental allele completely masks the effect of other.

As per the given information in the question, when true-breeding, red snapdragons are crossed with true-breeding white snapdragons, they produce pink colored offspring. This means that neither of the parental gene is dominant over the other.

When both are cross bred, they will represent a heterozygous state ( when alleles for both the snapdragons are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits). This represents blending of the parental trait.

Ugo [173]

Answer:

Voltage-gated Ca2+ channels

Explanation:

Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.
