What best explains snowshoe hare–lynx population cycles?
jasenka [17]

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.

Your heart pumps blood at variable rates depending on your degree of physical activity or neural/hormonal activity (this is call
GaryK [48]

Answer:

Explained

Explanation:

No, Homeostatic regulation requires Three components namely, a receptor, a control center and an effector. Without a receptor, there cannot be homeostatic regulation. Even though it seems that heart rate varies and returns to some number, this is not technically homeostatic regulation.  Blood pressure is homeostatically regulated - it has baroreceptors that monitor pressure, the brainstem that receives the information and nerves that then activate blood vessels to constrict or dilate to correct pressure (as well as other effectors) - but heart rate is not. Heart rate is not monitored by any neuron. Absolute water content of the body is not homeostatically regulated either - no neuron detects the number of water molecules, although neurons do detect the relative saltiness of the body.

Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA. Why? A.
meriva
I think the correct answer from the choices listed above is option A. Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA because the genes expressed in inskin cells may not be expressed in nerve cells and vise versa.
