Answer:
How do limiting factors affect population size?
Explanation:
Limiting factors are factors that affects the size of a population and slows down its growth rate or stop it in its entirety.
These factors include food, space, temperature, sunlight etc.
Limiting factor like food can affect a population greatly like not having enough preys in a forest, therefore the predators are starved to death or even in a fish pond where there is high competition for space (overpopulated) which leads to oxygen deficiency i.e they compete for oxygen as well, and this can lead to death as well.

Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.
Answer:
Option (4).
Explanation:
Respiratory system may be defined as the system involves in the exchange of gases between the tissue, lungs and the outside environment. The respiratory system involves nose, mouth, larynx, trachea, lungs, brochi, alevoli and alveolar ducts.
The oxygen is inhaled in the body and carbon dioxide is exhaled out from the body. The oxygen is transferred into the blood stream by binding of oxygen with hemoglobin. The oxygen is diffused in to body due to the partial pressure difference of oxygen and carbon dioxide.
Thus, the correct answer is option (4).
