Answer:

Interphase: Lowest pic, left corner.

Cell appears to be in a normal state.

Metaphase: Left, above Interphase.

Chromosomes are beginning to align in the middle of the cell. Spindles form and begin to attach to their centromeres.

Anaphase: Lowest right pic.

The chromatids are pulled away from each other and brought to different sides of the cell.

Telophase: Above Anaphase.

The genetic material is now in its respective side of the cell, which now begins to split into 2. Nucleic membrane begins to form.

Cytokinesis: Above Metaphase.

The clevage furrow is forming and separating the cytoplasm and other organelles in the cells. When done, this will result in 2 identical cells (unless it's meiosis II).

The study of psychoneuroimmunology suggests that when a stressful situation is encountered, several biological reactions occur,

zhenek [66]

Answer: d) lightheadedness or unconscious episodes.

Explanation:

There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:

1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.

2. The stage of resistance- this occurs till the stress is removed.

3. The stage of exhaustion

A method used by horticulturalists when they rotate the use of fields—planting crops on a particular piece of land for a period

svetoff [14.1K]

Answer:

The correct answer will be- Crop rotation

Explanation:

When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.

Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.

The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".

Thus, crop rotation is the correct answer.

Which two molecules generated by the Krebs cycle pass their high-energy electrons to the electron transport

Sidana [21]

<u>Answer</u>:

The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and FADH2

<u>Explanation:</u>

The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC) is also referred as the chemiosmotic phosphorolation.
