It’s either A or B
Diseases can often cause a decrease in the population
But also without healthy grass for them to eat, they begins to die off cause of not a lot of food left for them to eat enough to survive.
Answer:So yes,humans and other mammals (like dogs) have same immune system. Differences may occur in the protein structures, but they all come in same family and work similarly like humans.

Answer:
3) B
4) A
5) B
Explanation:
3) Sun heats up the air of a particular region due to which the air heated rises up ( as hot air is lighter than cool air ). When the hot sir rises , the cool air from other region comes there & like this wind blow.
4) A toaster uses electricity to produce heat in order to toast bread So here the electric energy is converted to thermal energy.
5) Windmills , Hydroelectricity dams & Ethanol plants have turbines & turbines do have a generator which is to be rotated . When the generator is rotated , electricity is generated.
Answer:
probably tectonic plates would shift
Answer:
The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it indicates low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.
Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb, decrease affinity and easily unloaded to muscles.
<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.
As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules binding by Hb, and easy release to respiring cells.
