The discovery of the Cell Theory has greatly impacted modern science. These have a membrane surrounding their nucleus as well as one surrounding the cell itself. In conclusion, the cell theory has helped scientists successfully study cells and their functions using microscopes and other advanced technology.

Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.
The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
<h3>The normal flora of the alimentary tract</h3>
Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.
These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.
From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.
The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.
Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

Answer:
The options
A) "Medications are needed to prevent heart failure."
B) "I will take aspirin, atenolol, and captopril indefinitely."
C) "My blood pressure should be less than 130/80 mm Hg."
D) "Daily estrogen will prevent another heart attack."
The CORRECT ANSWER IS D)
D) "Daily estrogen will prevent another heart attack."
Explanation:
A reduction in the natural hormone estrogen levels could be a causative factor in heart disease increase within post-menopausal women. Estrogen is thought to show a positive impact on the inner layer of artery wall, functioning in such a way to keep blood vessels elastic.
In spite of the advantages of estrogen, the American Heart Association speaks against employing postmenopausal hormone therapy to decrease the likelihood of coronary heart disease or stroke as some research works have revealed that it vividly do not decrase the risk of heart attack but increases the likelihood of blood clots and stroke.
