Answer:

The blue allele is dominant to the yellow allele.

Explanation:

The blue allele is dominant to the yellow allele, because there is more of the blue allele than the yellow allele.

Answer:

The blue allele is dominant to the yellow allele.

Explanation:

This is a cross involving a single gene coding for flower colour in a particular plant. The flower colour gene possesses two alleles viz: blue allele (B) and yellow allele (b). A truebreeding plant is that which produces only one type of offspring and contains the same allele for a particular trait (colour in this case).

According to the question, a truebreeding blue flower (BB) is crossed with a truebreeding yellow flower (bb) to produce an all blue-flowered offspring in the F1 generation. This is because the blue allele (B) is dominant over the yellow allele (b) in that gene i.e. the blue allele will mask the phenotypic expression of the yellow allele in the heterozygous F1 offsprings (Bb) that were produced.

In his law of dominance, Mendel called the allele that masks the expression of another like the blue allele in this question, DOMINANT allele while the allele that is phenotypically masked or covered up like the yellow allele in this case, RECESSIVE allele.

Rzqust [24]

Answer:

The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve(cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon.[3]Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.[4] The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic

The benefits are Beaches are better protected against erosion.

Trenches created in the ocean encourage species growth.

WhatWhat are the advantages and disadvantages of beach nutrition?

Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.

Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.

The inability of the body to adequately circulate blood and oxygen to the body's cells is known as
Arada [10]
Circulation of the blood is crucial in the body since it helps in supply of nutrients and oxygen to all parts of the body. It is these nutrients and oxygen that are key in the activities of a cell or a tissue without which the cells wont efficiently carry out their functions.The inability of the body to supply blood and oxygen to the body cells as required is known as hyperfusion. Hyperfusion is caused by inadequate perfusion of the body tissues and thus resulting to inefficient supply of nutrients and oxygen gas to the body cells and tissues.
