Answer:

Heart and Brain

Explanation:

While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.

The heart is at the center of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body. Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly.

Explanation:

Most bacteria are classified into two main categories

i) Gram positive bacteria and ,

ii) Gram negative bacteria.

They are classified on the basis of their cell wall composition and as well as by the reaction to the Gram stain test.

Gram positive bacteria's characteristics

ii) they have cell walls composed mostly of peptidoglycan.

i) stain purple after Gram staining.

Suppose two BbCc mice are crossed together. Assuming that the two genes assort independently, what are the expected phenotypes,

Katyanochek1 [597]

Answer:

4 types of phenotypes with phenotypic ratio 9:3:3:1 will be obtained.

Explanation:

The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.

It is clear from the diagram attached that the phenotypic ratio will be 9:3:3:1

The following 9 genotypes will show dominant trait for both the characters i.e. characters represented by B & C genes.

BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc

The following 3 genotypes will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.

BBcc, Bbcc, Bbcc

The following 3 genotypes will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.

bbCC, bbCc, bbCc

The following genotype is the only genotype which will show recessive trait for both the characters represented by gene B & C.

bbcc

The process of land becoming a desert because there are no plants to help hold and cycle water. a erosion b . weathering C. dese

8090 [49]

Answer:

Option-C

Explanation:

Desertification refers to the formation of barren land from the arid land due to many factors which could be climatic or anthropogenic. The climate factors include no rainfall, arid conditions, less water and water bodies, overgrazing by animals and many others.

As a result of these factors, the plants die or are unable to hold the soil. This leads to loosening of soil which causes soil erosion. This converts the fertile land into infertile land and the land becomes barren.

Thus, desertification is the correct answer.
