Answer:

<h3>MITOSIS AND MEIOSIS*</h3>

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

<h3>What meiosis means?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

<h3>What is mitosis explain?</h3>

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

<h3>What is meiosis important?</h3>

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

<h3>What is Mitosis important?</h3>

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

<h3>What Meiosis explain?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins following one round of DNA replication in cells in the male or female sex organs.

Which accurately describes gymnosperms? Check all that apply. Some of them lose their leaves in winter.Some of them lack seeds.S

AleksandrR [38]

I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)

</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

A constant rate of increase (rmax) for a population produces a growth graph that is J-shaped rather than a straight line. Why?

Alexus [3.1K]

Answer:

Explanation:

The line graph illustrates the temperatures in London, New York and Sydney on monthly average and the table introduces the information about the annual hours of sunshine for these cities. The overall view is that London is always exceeded by the rest in both the temperature and the number of sunshine hours.

To specify, the line graph shows that in New York, the average temperature goes up slightly from 4.5 degree in January to 8 degree in March, before a more significant increase to the highest of 30 degree in July, followed by a drop to 5 degree in December. Similarly, in London, after climbing gradually from the lowest point of 9 degree to the highest of 23 degree in July, the figure stays unchanged in the next month and then fall to 9.5 degree in December.

On the contrary, in Sydney, the temperature decrease insignificantly from 25.5 degree in January to the lowest of 16 degree in July, before a gradual rise to 25 degree in December. Meanwhile, the table indicates that New York has the largest number of sunshine hours per year with 2535 hours, came after by Sydney and London with 2473 hours and 1180 hours respectively.

In conclusion, London is likely to be the coldest city because its annual hours of sunshine is less than two others.
