Which of the following is an example of
negative feedback?
A. erosion of soil that results in increased amounts of
erosion
B. exponential population growth leading to more births
and higher population growth rates

C. melting of arctic ice leading to higher and higher global
temperatures and more ice melting
D. water moving into the roots of plants and out of leaves
leading to more water moving into the roots
An example of negative feedback is ; ( D ) water moving into the roots of plants and out of leaves leading to more water moving into the roots.
What is a Negative feedback ?A negative feedback is the reverse effect of the output of a stimulus. Feedback is the effect of the output of a system on the stimulus from the origin. Water moving into the roots of plants and out of leaves leading to more water moving into the roots is a negative feedback.because if the water flows into the roots and out of the leaves is suppose to lead to water moving out of the roots.
Hence we can conclude that An example of negative feedback is water moving into the roots of plants and out of leaves leading to more water moving into the roots.

What happens if a spike protein changes shape
Answer:
When a spike protein changes its shape, it folds on itself and merges its membrane within our cell's membrane to allow itself a way in, causing an infection and the penetration of host cells.
When a spike protein changes shape, it can affect the way a virus interacts with its host cell.
What is a spike protein?The spike protein is a key component on the surface of some viruses, such as coronaviruses, and is responsible for binding to host cell receptors, allowing the virus to enter the cell and cause infection.
If the spike protein changes shape, the following can happen:
Altered binding affinity: The ability of the spike protein to bind to host cell receptors may be enhanced or diminished. This can potentially affect the transmissibility or infectiousness of the virus.
Immune system evasion: A change in the spike protein shape might make it harder for the host's immune system to recognize the virus, potentially allowing the virus to evade detection and neutralization by antibodies.
Impact on vaccines: Changes in the spike protein shape could also impact the effectiveness of vaccines designed to target the original spike protein, as the altered shape may not be recognized as effectively by the immune system.
Overall, when a spike protein changes shape, it can have various consequences for viral transmission, immune system response, and vaccine effectiveness.

If unicellular organism swims from a hypertonic to an isotonic environment, will its contractile vacuole becomes more or less active?
When a unicellular organism swims from a hypertonic to an isotonic environment, its contractile vacuole becomes less active.
What is an Hypertonic solution?A hypertonic solution is one in which the concentration is greater than the surrounding environment.
An Isotonic solution is one in which the concentration is equal to that of the surrounding environment.
When a unicellular organism swims from a hypertonic to an isotonic environment, its contractile vacuole becomes less active since the solution are the same.
Therefore, the contractile vacuole will more active.

Why do you think scientists would be interested in studying cognitive behavior in animals?
Animals are used as models to learn about the human heart and lungs, and they are also utilized to learn about the human brain and nervous system. The brain, on the other hand, is far more sophisticated and nuanced than any other organ. Furthermore, animal cognition research tries to avoid issues such as which animals are smarter than others, instead concentrating on more particular concerns such as the ones listed above. Scientists frequently state that they are more interested in how well an animal has evolved to flourish in its environment than in its intelligence.

What elements make up the skeletal system?
a.
Bones, joints, and connective tissue
b.
Organs, muscles, and bones
c.
Bones and fascia
d.
The pulmonary and systemic circuits
Answer:
A
the answer is A!!! good luck <3
Answer:
A. Bones, joints, and connective tissue
Explanation:
The skeletal system supports and protects the body while giving it shape and form. It is composed of bone, joints, ligaments, connective tissue, and cartilage.
Organs are not included, for they are not skeletal. Fascla is a sheet of connective tissue beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. It is not part of the skeletal system.
A systemic circuit is the path of circulation between the heart and the rest of the body. It too, is not skeletal.
Hence, the answer is A.
