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.

Identify each event as the result of mechanical weathering or chemical weathering.
kow [346]

<h3><u>The following events are identified as chemical weathering:</u></h3>
  • The minerals in a marble statue react with water to form acids and pores in the structure.
  • The rocks in a region are streaked orange after being exposed to repeated rains.

<em><u>Reason: </u></em>

When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.

In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.

<h3><u>The following events are identified as Mechanical weathering:</u></h3>
  • A piece of rock crumbles after being constantly thrashed by strong waves.
  • Industrial runoff forms cracks in a rocky structure in its path.

<em><u>Reason:</u></em>

When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.

In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.

What is the function of the light-dependent reactions?​
lara31 [8.8K]

Answer:

The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
