The 2 basic functions of meiosis are to

Maintain chromosome number through generations

Cause genetic variations by recombination.
stira [4]3 years ago

Answer:

The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.

In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.

It helps in the formation of gametes in sexually reproducing organisms.

These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.

In absence of meiosis, the chromosomal number would have doubled after each generation.

In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.

During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.

Answer:

C

Explanation:

Ice-covered surfaces are highly reflective of the sun's rays therefore prevent those areas from warming as much as the areas where the ice is replaced with darker, less reflective surfaces which absorb heat and thus contribute more to global warming. Albedo is the percentage of radiation reflected by the earth's surface. Clear surfaces have greater albedo values than dark surfaces.

Which expression best illustrates the idiosyncratic nature of stress?
solniwko [45]
Idiosyncrasy means unusual or odd. It is used to show peculiarity. Thinking of stress usually means something negative thus would lead to giving the wrong impression of it's nature. Stress would only mean a reaction to a demanding or sometimes a changing environment. In the following idioms, the best expression would be "beauty is in the eye of the beholder" which means not all people have the same opinion on what is beautiful or attractive that means if correlate with stress it is up to the person on how he or she view stress,may it be a negative one or a positive one.
