Answer:
- cell wall -
Explanation:
The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.
So tell yourself does, an animal that already has a skeleton, need the cell wall?!
NO! It dan't! That's why animals don't have the cell walls and plants do.
!!! Hoped that helped !!!
When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.
What is cell wall?A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.
It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.
The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.
It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.
The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.
Thus, the correct option is D.

During exercise, the blood is travelling more quickly around the body. This carries more oxygen to the exercise muscles. Describe other changes in the athlete's body that enable more oxygen to be taken in at the lungs.
Answer:
your heart rate goes up explaining why the blood is traveling quicker. this causes you to breath faster meaning bring more oxygen to the blood in your lungs faster. your blood pressure also goes up from the increase in heart rate.
Answer:
the breathing rate and volume of each breath increases to bring more oxygen into the body
Explanation:
it removes the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

Would a light source be considered an internal or external stimulus?
For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.
What is stimulus?A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.
An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.
Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.
A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.
Thus, it can be concluded that light is an external stimulus.
