Biology

kaheart [24]3 years ago
7 0

Answer:

A polygenic trait can be described as a physical trait which is influenced by more than one gene.

The three types of selection for a polygenic trait are:

1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.

2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.

3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.

Ratling [72]

A neuron is a specialized cell,  found in the brain, spinal cord and the peripheral nerves  known as the nerve cell. The structure of a neuron varies with their shape and size and it mainly depends upon their functions

<h3>what is the structure of neuron ?</h3>

Dendrites which is A branch-like structure that functions by receiving messages from other neurons and allow the transmission

Cell Body has a cell body with a nucleus, Golgi apparatus, endoplasmic reticulum, mitochondria and other components.

Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals

Synapse functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.

IceJOKER [234]

Answer:

To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same
