Answer:
Parenchyma – They are living cells and walled, soft in nature due to the presence of thin-walled cells. Collenchyma – These are characterized by uneven thick-walled living cells. Sclerenchyma – They have cells with thickened lignified walls, providing them strength and making them waterproof.

i got that from my biology notes
Answer:
b. the interaction of food availability and predation intensity
Explanation:
The complete question is as follows:
What best explains snowshoe hare and lynx population cycles?
a. the seasonal trends in food availability
b. the interaction of food availability and predation intensity
c. natural variation in the number of lynxes born
d. the population density of snowshoe hares
- The population of snowshoe hare and lynx are closely linked to each other and this is because the primary food of lynx is the snowshoe hare.
- When the number of hares is more lynx eat more of hares and less of other food and when the number of hares is scarce, lynx eat alternate food.
- However, in the scarcity of hares, the other foods do not provide lynx with their nutritional needs and therefore, many of them leave their home grounds.
- Therefore, when the hare number declines lynx number also declines.
- The population cycle spans over 8-11 years.
- The number of hares decreases at the end of the cycle and so does the number of lynx.
- However, at the beginning when the number of the hare is more, they starve due to competition and are easily caught by the lynx and thus, the lynx population also increases.
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product. Which is then needed for cellular respiration.
Answer:
Hypocalcemia is defined as low level of calcium in the serum.
It could be harmful to an individual in the following ways:
Convulsions, arrhythmias, tetany, and numbness in the hands and feet and around the mouth occur due to lowered threshold for depolarization causing increased responsiveness.
Life-threatening complications- Laryngospasm and Cardiac arrhythmias can arise.
Effects on cardiac output include:
(A) Negative chronotropic effect, or a decrease in heart rate.
(B) Negative inotropic effect, or a decrease in contractility
