Why do human traits such as height and skin color have many different phenotypes?

Biology
1 answer:
Dima020 [189]3 years ago
5 0
In fact, there is an enormous variety of phenotypes for height. Some human traits show a large number of phenotypes because the traits are controlled by many genes. The genes act together as a group to produce a single trait … Skin color is another human trait that is controlled by many genes.

A botanist discovers a new species of land plant with a dominant sporophyte, chlorophylls a and b, and cell walls made of cellul
olchik [2.2K]

Answer:

e. spores

Explanation:

In the given question, the characteristics of a plant are mentioned which are the dominant sporophyte, cell wall and the Chl a or b.

It is mentioned that the plant has a dominant sporophyte therefore it produces the spores during its life cycle. The other features like the endosperm, seeds, flowers are the characteristics on the basis of which the plant can be characterised as they differ in the plants.

Since the production of spores is a characteristic feature of the sporophyte, therefore, it will be least considered by the botanist to discover a new species.

Thus, Option-E is the correct answer.

Why are there only 20 amino acids when there are 64 variants of triplets?
Montano1993 [528]

Answer:

The genetic code is degenerate.

Explanation:

The genetic code is degenerate: there are 64 triplets of different codons (sequence of three bases of mRNA that codes for a certain amino acid) and 20 amino acids. That is, an amico acid can be encoded by more than one codon.

Much of the regulation of gluconeogenesis is a result of the inhibition of?
matrenka [14]

The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Discussion about the statement:

The cytosol is the site of all glycolysis and gluconeogenesis processes. The rate at which glucose is produced in the body is inversely related to the intake of carbohydrates. The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Fructose 2,6-bisphosphate is an intermediate that plays a crucial role in controlling both glycolysis and gluconeogenesis. This metabolite's presence can promote glycolysis and prevent gluconeogenesis.

Control of Gluconeogenesis and Glycolysis

  • At various crucial stages of glycolysis and gluconeogenesis, metabolic control takes place. The catalysts that accelerate each of these stages can be activated or inhibited by outside forces, for example, the quantity of a molecule that comes after. The conversion of glucose and ATP into glucose 6-phosphate is the first controlled step in glycolysis. Keep in mind that hexokinase catalyzes this process.
  • High levels of blood glucose, AMP, and low levels of cellular ATP all trigger the activation of hexokinase. In other words, the glycolysis process is enhanced when blood glucose levels are high. Whenever cellular ATP levels are low and AMP levels are high, glycolysis is also increased. Both of these instances show that the cell is short on energy and may be directly influenced to create additional energy.
