Chromosomes exchange genetic material in step 3.

<h3><u>Explanation</u>:</h3>

The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.

The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.

During embryonic development, the vertebral column is replaced by the notochord.
Reptile [31]

Hello! The answer is false.

It is actually the opposite. The notochord is a primitive axial skeleton, and in humans, it disappears. It eventually becomes part of the vertebral column, which is the backbone that we have today.

Hope this helps!

Within a given species, which two types of cells have the equivalent amounts of dna?
kiruha [24]
The original question has a set of choices. This is within the context of cell division. The choices are:

A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.

Explain the types of acid deposition
Pepsi [2]

Answer:

Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.

Explanation:

The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.

lilavasa [31]
José probably doesn't feel any pain because his body, during and after exercise released endorphins which are endogenous opioids. This endorphins promote a sense of satisfaction and pleasure, and make pain and discomfort feel irrelevant.

bearhunter [10]

Answer:

A. insects fly around a bright lamp at night

Explanation:

insects are naturally attracted to light  due to presence of positive phototaxis.  Insects revolve around the light in the same way as electrons do around the nucleus.
