The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator changes very little through out the year and has summer like conditions for most of the year.
However the other regions may receive direct sun rays but for far more limited periods. In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most direct rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.
This is not even a question. Is it a true or false question if so tell us.
Mechanical digestion is the breaking down of food into smaller pieces physically. Mechanical digestion begins in the mouth as the food is chewed.
but in the case of chemical digestion, it breaks the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.

In black bread mold spores are produced in structures called Sporangia. Black bread mold are fungus that reproduces in the same way like most molds. The molds make spores inside a sporangium and when the spores are ready to leave and spread more mold, the sporangium breaks open and lets the spores out.
