Biology
1 answer:
IceJOKER [234]3 years ago
8 0

Answer:

112.5 KJ

Explanation:

Energy = Power x Time

Time = 25 minutes

         = 25 x 60 sec = 1500 sec

Power = 75 watt

Energy = 75 x 1500

                112,500 Joules

Energy in KJ = 112,500/1000

                     = 112.5 KJ

__________ is required for collagen synthesis, and a deficit of it results in a condition called scurvy.
iren [92.7K]

Answer:

Vitamin C

Explanation:

Vitamin C is known as the ascorbic acid performs various functions in humans and is present as the constituent of the skin epidermis.

Vitamin C protects the skin from photodamage caused by the harmful UV radiations and helps in the synthesis of collagen, a type of connective tissue in the human body. Vitamin C is involved in the hydroxylation of collagen synthesis which is important for the support of the epidermis and extracellular stability.

The deficiency of Vitamin C causes scurvy characterized y the fragility of blood vessels and bleeding.

Thus, Vitamin C is the correct answer.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter
podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

  • p^2 + 2pq + q^2 = 1

where;

  • p^2 is the h0m0zygous dominant phenotype frequency
  • 2pq is the heterozygous phenotype frequency
  • q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Why is genetic variation important? Select all that apply:
Sladkaya [172]

Answer:

Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.

Explanation:

Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.
