Pollution of water bodies due industrial wastes kills aquatic organisms and this disrupts food source for humans.
What are the effect of silt on aquatic organisms?Silt refers to small fine particles of sand or mud that forms a suspension in water.
Silt in oceans usually come from rivers opening into the sea
The silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea will originate from rivers and streams opening into the sea.
The silt will reduce the population of algae on the coral reef as they increase water turbidity.
This will reduce fish population in the area and the food source for humans.
Industrial wastes are a source of mercury in lakes.
The presence of mercury will poison the lake and kill the fishes in the lake.
It will also make the water unfit for drinking by humans.
Therefore, pollution of water bodies kills aquatic organisms and this disrupts food source for humans.

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.

A. What is the principle of uniformitarianism? (5 points)
B. How does this principle make it easier for geologists to understand Earth's past? (5 points)
Answer:
A. What is the principle of uniformitarianism?
Uniformitarianism would therefore be a theory of the Earth characterized by the uniformity of physical laws, processes and the rhythm with which they have acted in nature (gradualism).
B. How does this principle make it easier for geologists to understand Earth's past?
In geology, uniformitarianism has included the gradualist concept that "the present is the key to the past" and that geological events occur at the same rate as they always have, although many modern geologists no longer hold to strict gradualism.

Explanation:
Question 1. - Decomposers break apart dead organisms into simpler inorganic materials, making nutrients available to the plants/primary producers.
Question 2. - Energy decreases as it moves up trophic levels because the energy is lost as metabolic heat when the organisms are consumed by other ones from the next level.
Question 3. - Energy moves through an ecosystem in a single direction from the sun to autotrophs/producers, then from producers to heterotrophs/consumers. Never backward from consumers to producers.
Sun ⇒ Producers ⇒ Consumers ⇒ Decomposers
Question 4. - See Question 1.
Question 5. - Autotrophs don't need energy from other organisms. Instead, they use photosynthesis to get their food.
- Note: Fungi cannot make their own food and therefore are not autotrophic. They do not have chloroplasts, instead, they are osmotrophic!
