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!

An independent variable is a variable that is changed or manipulated in a scientific experiment to examine how it affects the dependent variable.

Relies on the variables you're using and the functions connecting them. A variable is dependent or independent, depending on whether its value changes as a result of a change in another variable.

In a scientific experiment, an independent variable is a variable that is altered or controlled to see how it impacts the dependent variable.

The variable being tested and measured in an experiment is referred to as the dependent variable.

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.

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.

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.

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.

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.

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.

I guess this is the correct answer

When a unicellular organism swims from a hypertonic to an isotonic environment, its contractile vacuole becomes less active.

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.

= Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta.

= Euglena belongs to Kingdom Protista and the Phylum Euglenophyta.

= Chloroplasts carries out photosynthesis.

= The flagellum is located on the anterior (front) end, and rotates in such a way as to pull the cell through the water.

= Autotrophs are known as producers because they are able to make their own food from raw materials and energy.

= Heterotrophs are known as consumers because they consume producers or other consumers.

= Euglena have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food.

= The function of the nucleus is it contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus.

= The function of the contractile vacuole is that, it helps the cell remove excess water. If the cell did not have this organelle, the euglena could take in some much water due to osmosis that the cell would explode.

= During unfavorable conditions, the ameba can create a cyst, this hard walled body can exist for a long period of time until conditions become favorable again.

= The Fingerlike extensions of the ameba's cytoplasm are called .l Pseudopodia.
