Answer:

soooo what's the question?

Explanation:

Also, salty water can be frozen and melted into fresh water. Boiling water also helps get rid of bacteria, and we can reuse deep sea water with a piping system of some sort (I read about that in National Geographic. It's a project they were working on)

The mitochondrial matrix has what charge compared with the intermembrane space?

Solnce55 [7]

The matrix (inside mito) has a negative charge compared to the intermembrane space (outside of mito but still inside) because positively charged protons are constantly pumped from the matrix to the intermembrane space. A cell oxidizes an organic molecule producing 3 NADH molecules and 3 FADH2 molecules..

Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.

Effectus [21]

Answer:

Enzyme activity decrease at these temperatures. 

Explanation:

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH. In dark reactions carbon is fixed using the ATP and NADPH. 

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about 10°c - 20°c. At low temperatures and high temperatures enzyme activity is less efficient.

At a temperature above 38°c and below 0°c enzyme activity decreases.

Molly's cut is bleeding and she is worried that it will not stop. Using your knowledge of the homeostatic process, what would yo

olga nikolaevna [1]

Answer:

Tell Molly that the bleeding will stop because hemostasis is the way the body stops blood loss when something happens to a vessel. This is the process of the blood clotting. If we didn't have hemostasis bleeding would continue. Unless she has hemophilia, the blood will stop. The first thing that happens is vascular constriction, then formations of platelet plugs, then the blood clots (coagulation) last the fibrous tissue grows (Fibrosis and fibrinolysis)

Why are scientists warning that exclusively growing this mutant type by asexual reproduction presents a serious disadvantage?

Alla [95]

Answer:

Asexual reproduction can be described as a process in which daughter cells are produced which are 100% identical to the parent cells. Unlike the process of sexual reproduction, no recombination occurs in asexual reproduction. Hence, no variability is produced when organisms reproduce by this method.

As there will be lack of variability in asexual reproduction, the whole of the particular species might become endangered or extinct due to a disease or due to other factors like pests.
