Viruses are not alive. Although they sort of “hack” a host’s cells and reproduce, they do not breathe or move on their own. A virus will sit on a counter forever if it’s untouched. Viruses are spread by physical contact, not because they can move around on their own.
Although viruses can attack and hack, and use your cells to reproduce, they are programmed to do so.
Cells are very much alive, while viruses are not.

In pea plants, purple flowers are dominant to white flowers. Suppose two heterozygous purple-flowered plants (Tt) are crossed. W
iris [78.8K]

Answer:

75%

Explanation:

This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (T) is dominant over the allele for white flowers (t).

According to the question, two heterozygous purple-flowered plants (Tt) are crossed i.e. Tt × Tt. The following gametes will be produced by each parent; T and t. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

TT, Tt, Tt, and tt.  

Since purple allele (T) is dominant, offsprings TT, Tt, and Tt will be phenotypically purple-flowered. Hence, ¾ × 100 = 75% of offsprings will have purple flowers.

What are two theories proposed to explain Primate Origins and how do they relate to traits we see in modern primates
GREYUIT [131]

Answer:

The level of specialization is given by the function.

The function of the organ makes the cell as it becomes mature, its more specific function becomes.

First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.

After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.

Explanation:

The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.

timurjin [86]

Answer:

The correct answer is - citric acid cycle.

Explanation:

In the third condition, fresh NADH molecules are not forming as NAD+ is getting accumulated fresh NADH molecules are continuously released or generated from the citric acid cycle.

There is no NADH production occurs which means there is some problem with citric acid cyle. Other conditions given is also the result of this inhibition occurs in the citric acid cycle that are decrease in proton gradient and ATP depeletion.
