Answers

When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing al the time. When cells become damaged or die the body makes new cells to replace them.

A. Transpiration
B. Evaporation
C. Condensation
D. Precipitation

what is made when a sperm cell combines with the polar nuclei?

Answers

Answer:

Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).

Answer:

endosperm

Explanation:

The second fertilization results in the endosperm, which is a special tissue used to nourish the embryo.

With Poland overrun by German armored columns now poised to strike at France, and China under assault by Japan, Americas commanders had to prepare the US military for war. The problem was not a dearth of troopsafter Adolf Hitlers blitzkrieg rolled through Poland in September 1939, Congress had mobilized the National Guard and Reserve and approved an increase in the size of the Army. It was that the existing troops were poorly trained or not trained at all.No one was more acutely aware of this than Army Chief of Staff General George C. Marshall. A student of history, Marshall was certain American boys were as courageous as any German or Japanese soldier, but they lacked sufficient training and combat experienceand time was short.
