Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
- It was a weakly reducing atmosphere
- It was hotter
Explanation:
The primordial earth’s atmosphere was mainly composed of carbon dioxide and methane. These are greenhouse gases that kept the temperatures of the atmosphere high because they trap infrared radiation that reflects off the earth's surface. These gases also made the atmosphere a reducing atmosphere due to the absence of oxygen. The most likely source of carbon dioxide was frequent volcanoes at the time and the methane from early anaerobic microbes.
The atmosphere changed when photosynthetic organisms evolved and caused the Great Oxygenation Event because they evolved oxygen.

Cholesterol can be controlled by ingesting soluble fibers. Option B is correct. Binding cholesterol and carrying it out of the body with the feces.
<h3>
How do soluble fibers absorb cholesterol?</h3>
Once in the intestine, soluble fibers hydrate and form a gel that binds the digestive tract with bile acids necessary to absorb cholesterol and other lipidic compounds.
By binding to the intestine walls, soluble fibers avoid the organism's cholesterol absorption.
Cholesterol is absorbed by this gel and eliminated through the feces.
Soluble fiber fermentation also favors short-chain fatty acids formation, helping to inhibit hepatic cholesterol synthesis.
Option B is correct. Binding cholesterol and carrying it out of the body with the feces.

To calculate the basal energy that's needed, by using the rule-of-thumb
guideline, you have to multiply the weight (in kilograms) by 0,9(kcal per kg per hour) for women and 1 <span>(kcal per kg per hour) </span>for men and by the number of hours.
</span>
132 pounds=60kg
60kg x 0,9 kcal x 24 hrs=1134 kcal
Actually, its chance is 25%. A grey cat holds the alleles BW. A grey cat (BW) crosses with a black cat (BB). The percentage is 25% because the allele, “W” is present two times.
