Answer: Four pulmonary veins.

Explanation: Oxygen and nutrient rich blood will flow from the lungs back into this part called the left atrium (Or as some will call it, the left upper chamber in the heart). From there, it goes through four pulmonary veins.

Hope I could help! :)

Can someone help match these defenitions.

luda_lava [24]

The right matches are:

1. nuclear envelope is matched with b.

2.centriole is matched with a.

3.interphase is matched with j.

4.furrowing is matched with h.

5.anaphase is matched with g.

6.spindle apparatus is matched with f.

7.chromatin is matched with i.

8.haploid is matched with c.

9.meiosis is matched with e.

10.homologous chromosomes is matched with d.

Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort

Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide $(CO_2)$ , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

<u>Explanation:</u>

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - $(CO_2)$ combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.

A potential negative health effect of stress is _______

Minchanka [31]

Correct option a) Increased plasma volume.

A potential negative health effect of stress is Shrinks the brain. Stress that's the left unchecked can contribute to many health problem, such as high blood pressure , heart disease , obesity and diabetes.

The volume of the brain tends to remain about the same, it has been found that chronic stress in healthy individuals can causes areas of the brain associated with emotions , metabolism and memory of that individual to be shrink slowly.

Stress can also be positive which is distress , getting job promotion or being given grater responsibilities keeping us alert and ready to avoid danger. It can became negative if a person faces continuous challenges without relief or relaxation between challenges.
