What part of the cell theory explains why your skin is able to repair itself after being cut

Cells are created from existing cells is the part of the cell theory which explains why the skin is able to repair itself. The body produces 300 million new cells every day. After getting a cut or scratch, the skin may start bleeding. This happens when the injury tears down the tiny blood vessels that is found under the skin’s surface. The body wants to stop the bleeding so the platelets will come to the rescue.

At the cut, platelets stick together. This is how the blood clots which then become a scab. This protects the area so the cells underneath it can have the time to heal. Beneath the scab, new skin cells multiply to repair the wound. Damaged blood vessels are restored and blood cells end the infection in the wound. And also, under the scab, a new skin layer is formed.

4. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If t
lisov135 [29]

Answer:

The correct answer would be:

  • Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
  • Phenotypic ratio: 3 (polka-dot tails) : solid colored tail

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).

<h2>Answer and Explanation </h2>

The cell respiration is a process in which the sugar molecules in the human body are broken into a form of energy which can be utilized by the cell. The cell respiration is needed to build up the adenosine triphosphate (ATP) and then it releases waste products from the cell. For this biochemical process, the cell uses oxygen hence, this process is also called aerobic respiration.
