Which stage is the dominant stage in mosses? Sporophyte Spores Gametophyte Gametes

Answers

The correct answer is - Gametophyte.

Mosses are bryophytes whose life cycle alternates with gametophyte and sporophyte. A gametophyte is haploid and forms the main plant body which is the dominant phase of moss plant. On gametophyte, male and female sex organs develop which produces male and female gametes respectively. After fusion of gametes zygote is formed which develops into sporophyte. The sporophyte is attached and dependent on the gametophyte for the nutrition.
Gametophyte is the dominate stage in mosses

Which process temporarily disrupts homeostasis because it increases an already high concentration of chemicals in the cell?

Answers

When cells in a body are not working properly and normally, they cause disruption in the body homeostasis.

Homeostatis is characterized as balance in the body but when there is any disturbance in the body, it breaks down the balance and cause imbalance. For example in the case of diabetes in which body fails to maintain the good amount of glucose in blood which results in imbalance the body which is why diabetic patients are asked to maintain and monitor their body sugar level to maintain homeostatis.

When the cells in your body do not work correctly, homeostatic balance is disrupted. Diabetes is a good example of this.

A renewablesource of energy is defined as the energy obtained from the renewable source that is replenished naturally.

All of the following are sources of renewable energy exceptnatural gas energy.

Renewable energy can be explained as:

  • Renewable energy is obtained from renewable sources like sun, biomass from plants, wind, geothermal, and hydroelectricenergy.

  • Natural gas is a naturally occurring gas that is a non-renewable source of energy because it cannot be replenished over time.

Thus, the correct answer is Option C.

Coordinate the immune system response by activating effector cells Memory B and T cells Helper T cells B cells Cytotoxic T cells

Answers

Answer:

Helper T cells

Explanation:

This is because it is a type of adaptive immune system that stimulate B cells, microphages and cytoxic T cells. Helper T cells are used in different adaptive immune responses. They help to activate B cells so as to produce antibodies and also help macrophages to destroy ingested microbes. they also help activate cytotoxic T cells which will inturn kill infected target cells.
