Like repels like when we're working with electrical charges. So positive repels positive and negative repels negative. When you have questions that ask which of the following or which of these or something like that, it's best to give us those options so we can give you the best help possible.
Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.

Some of the equipment the student can use are:
Nets
Underwater cameras
pH indicators
among others.
<h3>What does the student want to study?</h3>
The student wants to find out if there are invertebrates and fish or if the conditions of the pond would support these types of organisms.
<h3>What does the student need to do?</h3>
In this situation, there are two main approaches:
- Study invertebrates and fish: This approach implies finding out if there are already invertebrates and fish in the pond, to do this, the student can
- Directly observe organisms by using a special camera.
- Use a net to catch organisms in the pond and then classify the organisms.
- Study the conditions: This approach implies determining if the pond has the conditions for invertebrates and fish to live. To do this, the student will need to measure conditions such as:
- Nutrients in the pond.
- Temperature.
- Ph.
This will require equipment such as pH indicators.

The correct answer is: it releases sweat to cool down.
During the exercise, body temperature increases and as a result respiration releases energy in the muscles, the skin produces sweat, which evaporates from the surface of the skin. Evaporation takes heat energy from the body.
Energy needed to perform exercise is derived from anaerobic metabolism within the cytosol of muscle cells (anaerobic respiration).
