Does plants lose/gain water during turgor pressure? How does it benefit the plant?

1 answer:

5 0

<h2>Answer:</h2><h3>Plant cells need turgor pressure to maintain their rigidity and sturdiness. This is what gives a plant the ability to grow and stand tall. When the concentration of solutes is higher outside the cell, the plant cell loses water and the plant wilts.</h3>

<h3>Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.</h3>

To which functional class of proteins does lysozyme belong?

PSYCHO15rus [73]

Lysozymes are under the enzymes-functional class of proteins. Enzymes are the ones responsible for the acceleration of chemical reactions. These are the macromolecular biological catalysts. <span> When we say enzymes, these are proteins which are directly related to the facilitation of the biochemical reactions. These include lactase and pepsin. You can usually hear these when learning about specialty diets or digestive medical conditions. Some of the examples of this protein’s presence are found in tears, human milk, saliva, and mucus. It is because of their ability to break down bacterial cell walls in order to protein improvement and nucleic extraction of efficiency make these lysozymes important </span>proteins<span> in living organisms. The gene responsible for the encoding of the lyzozome enzyme is called the LYZ gene.</span>

Explain why two siblings except identical twins have the exactly the same alleles

Natali [406]

Answer:

having exactly the same DNA sequences, twins start accumulating genetic variation from the earliest stages of development, researchers at Iceland-based company deCODE genetics found, meaning that one twin harbors variants that aren't present in the other.

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
