The portion of the diencephalon that acts as a relay station for sensory impulses traveling to the sensory cortex is the _______
Hitman42 [59]

Answer: Thalamus

Explanation:

The thalamus part of the brain is known as the relay station for all the sensory information. This information can be any sought of smell, light, taste et cetera.

It is relayed further via thalamus. Myelinated fiber bundle originates from the lateral surface of thalamus and it terminates at the cerebral cortex.

It is a relay station for the information from brainstem, spinal cord and cerebrum towards the cortex.

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Allisa [31]

Answer:

Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.

Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.

Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.

Name 2 structures present in root hair cell that are not present in a red blood cell
vekshin1

Answer:

Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.

Is the muscular system the same as the nervous system?
Sauron [17]

Answer:

Nope!

Explanation:

Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive track.
