Answer:

Posterior column mediates a pathway called as posterior column medial lemniscus pathway in central nervous which is responsible for mediating certain sensations like touch, vibration etc. Damage to the left posterior column unable to transmit signals to the primary somatosensory cortex in the gyrus and parietal lobe of the brain.

Explanation:

The spinal cord and cerebrum is connected by some specialized tract called as white matter tract. These tracts are either ascending or descending.

The another name of ascending pathway is known as medial lemniscus pathway.

The origin of this pathway takes place within posterior column of the spinal cord.

Posterior column medial lemniscus pathway is important as it transmit signals to the cerebrum which is responsible for generating impulse like vibration, touch etc.

Thus damage to this column can't be able to transmit signals to different parts of cerebrum and thus impulse like touch, vibration,pressure etc will not generate.

The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors.

Discuss how temperature and amount of precipitation can affect the type of plants and animals found in the deciduous biome. guys

evablogger [386]

Temperature affects the type of plants because different plants require different temperatures and precipitation levels. Such as in the case of cacti, they need very little precipitation and can withstand very high levels of heat.

Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color

trasher [3.6K]

Answer:

This question is incomplete, the complete question is:

Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color. Red eye color is dominant to brown eye color. Use the Punnett square to determine the ratio of offspring with: Brown body and red eyes : Brown body and brown eyes : Black body and red eyes : Black body and brown eyes :

The answer is:

Brown body and red eyes : 9

Brown body and brown eyes : 3 Black body and red eyes : 3 Black body and brown eyes : 1

Explanation:

This question is a typical dihybrid cross involving two different genes. One coding for body color and the other for eye color. The allele for Brown body color (B) is dominant to the allele for black body color (b) in the first gene while the allele for Red eye color (R) is dominant to the allele for brown eye color (r) in the second gene.

In a cross between two parents that are heterozygous for the two genes i.e. BbRr × BbRr, each parent will produce the following possible allelic combinations of gametes:

BbRr- BR, Br, bR, and br

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced in the ratio 9:3:3:1 where the offsprings and their possible genotypes are;

Brown body and red eyes (B_R_): 9

Brown body and brown eyes (B_rr): 3

Black body and red eyes (bbR_): 3

Black body and brown eyes (bbrr): 1
