Answer;
A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.
Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.
Answer:
The two types of lipoproteins are low density lipoprotein and high density lipoproteins
Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.
High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.

Answer:
Maintaining a rich variety of genetic material that can lead to discoveries useful for humans can be ensured by preserving biodiversity.
Explanation:
Options for this question are:
- <em>Preserving biodiversity
.</em>
- <em>Increasing cloning
.</em>
- <em>Asexual reproduction
.</em>
- <em>Selective breeding.</em>
Biodiversity refers to the number of different living organisms that exist, and which are the product of evolution, those that have multiple ways of interacting, shaping life on the planet.
The human being is part of biodiversity, considered a natural heritage of the world and an element that provides balance to the biosphere.
An important characteristic of biodiversity is that it contains the different genetic information of each living being, each one of which is a functional element on which the maintenance of life on the planet depends, as well as the reservoir of the world's genetic potential, so it is necessary to guarantee its preservation.

If the ligaments of the joints contained high percentage of the elastic fibers then, the joints would have been more freely movable. They would be more stretchy and flexible. But the ligaments around the joints keep the bones together and aid in the controlled movements of these joints. If the percentage of the elastic fibers in the ligaments joining these is to be increased, then the joints will become floopy and will be prone to dislocation and misalignment.
