Answer:

The function of the villi and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface.

Explanation:

There, the villi and the microvilli increase intestinal absorptive surface area approximately 40-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion

How does interphase prepare a cell to divivde?
Ira Lisetskai [31]
The interphase prepares the cell to divide by enlarging the cell so that when it does divide, there will be space for the nucleus (if it applies to the cell) and the organelles. It will allow the cell to be able to function and later divide on its own. It replicates DNA so that the two future daughter cells will have an even number of chromosomes to remain the cell type that it's parent was.

Use what you know about atmospheric circulation and seasonal changes in the sun’s orientation to earth to explain the highly sea
viva [34]

Answer:

The Inter-Tropical Convergence Zone (ITCZ)region gets the most direct sunlight at any given period in time. This in turn causes air to be unstable with a drop in pressure and rise of air which cools and condenses into clouds to form precipitation causing the wet season in the tropics.

In this region, the sun is directly or almost overhead as seen during summer periods in the tropics.

Only in areas of the North and South of the ITCZ known as doldrums which at times are parallel to the ITCZ do we have high pressure that aren't conducive to precipitation causing dry season in the tropics.

In the ITCZ zone, we also have the tropical rain forests along the equator with huge amount of all round rain for the year.

Along the equator, on either side of the rain forests we have the dry and wet forests with the savannah to the North of this region and the southern hemisphere to the south of these forests since these forests are seen mostly in the ITCZ than the savannahs.

Rain shadows and ocean cueeebts may at times cause some savannahs to be along the equator and some rain forests -wet and dry forests- to be positioned further form the equator.
