Exotoxin virulence factor is a substance that directly damages cell membranes or enters cells and changes their function.

Exotoxin- Exotoxins are a class of soluble proteins released by bacteria that enter host cells and catalyze the covalent alteration of one or more components of the host cell in order to change the physiology of the host cell. Exotoxins are produced by both Gram-positive and Gram-negative bacteria.

Bacteria- Microorganisms that are unicellular, capable of autonomous reproduction, and generally free-living are known as bacteria. In nature, bacteria are found everywhere. The foundation of all life on earth, they are architecturally basic but functionally sophisticated creatures.

No stripe on the head (H) is dominant, a black stripe on the head is recessive. If dad's genotype is Hh, what are the odds that
olga55 [171]

The chance of the offsprings with stripe on head is 50%.

Option A.

<h3><u>Explanation:</u></h3>

Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.

So the genotype of the father which is given as Hh. He is heterozygous.

The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.

So the gametes from father is H and h. Whereas the gametes from mother is only h.

So the genotype of the offsprings are Hh and hh as 50% each.

So the probability of the offspring being striped head is 50%.

Survival of plants in terrestrial environment has been made possible by the presence of.
OlgaM077 [116]

The survival of plants in terrestrial environment has been made possible by the presence of conductive tissue.

Conducting tissues are vascular tissues that conduct water and nutrients throughout the plant. Plants have two conducting tissues:

  • Xylem: It transports water and minerals from the roots to the leaves. In non-woody terrestrial plants, the xylem can be found vascular bundles and in of woody plants it is found in the vascular cambium
  • Phloem: It conducts photosynthesized glucose and other metabolic products from the leaves to other parts of the plant.

Hence conductive tissues enable plants survive in terrestrial environment because it helps to transport water from the soil to the leaves for photosynthesis and transport the products of photosynthesis throughout the plant.
