The function of the nucleus is to protect the cell’s DNA and control cellular activities. Two of the structures that the nucleus depends on are ribosomes and the nuclear membrane. The ribosomes assist with protein synthesis. Rough ER contains ribosomes on its surface and transports proteins throughout the cell. Smooth ER makes lipids and distributes them within the cell.

Explanation:

As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. <em>We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources</em><em>.</em><em>we should prevent such resources for future generation also the future generation </em><em>should</em><em> get the chance to use such resources </em><em>.</em><em>the pollution is increasing day by day </em><em>.</em><em>we should control it </em><em>.</em><em>the main thing is that we should control the rapid population growth </em><em>population</em><em> </em><em>growth should be controlled due to this </em><em>global</em><em> </em><em>warming</em><em> </em><em>is</em><em> </em><em>increasing which is very dangerous </em><em>leading</em><em> </em><em>to the declination of ozone layer due to </em><em>which</em><em> </em><em>the</em><em> </em><em>harmful</em><em> </em><em>rays</em><em> </em><em>of</em><em> </em><em>sun</em><em> </em><em>may</em><em> </em><em>enter</em><em> </em><em>the</em><em> </em><em>earth</em><em> </em><em>which may cause various problems in us and cause various diseases due to </em><em>which</em><em> </em><em>we ma</em><em>y</em><em> </em><em>die</em><em>.</em><em>the main thing is that we should stop the population growth, we should conduct public </em><em>awareness</em><em> program</em><em>m</em><em>e</em><em>s</em><em> </em><em>and many more </em><em>programmes</em><em> </em><em> to educate </em><em>people</em><em>.</em><em> </em><em>Population growth al</em><em>s</em><em>o</em><em> </em><em>creates</em><em> </em><em>deforestation</em><em> </em><em>as</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>people a</em><em>r</em><em>e</em><em> </em><em>increasing day by day they need more place to l</em><em>i</em><em>v</em><em>e</em><em> </em><em>,</em><em>they need more Land due </em><em>to</em><em> </em><em> </em><em>t</em><em>his </em><em>they</em><em> </em><em>cut</em><em> </em><em> down the trees of forest and used to make houses there due to </em><em>which</em><em> </em><em>d</em><em>e</em><em>f</em><em>o</em><em>r</em><em>e</em><em>s</em><em>t</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em><em>takes </em><em>place</em><em>.</em><em> </em><em>we all know that d</em><em>e</em><em>f</em><em>o</em><em>r</em><em>e</em><em>s</em><em>t</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em><em>is the process of cutting down </em><em>trees</em><em>.</em><em> </em><em>so the tree should not be </em><em>cut</em><em> down </em><em>as</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>source</em><em> </em><em>of</em><em> </em><em>oxygen</em><em> </em><em>for</em><em> </em><em>all</em><em> </em><em>creatures</em><em> </em><em>living</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>whole</em><em> </em><em>world</em><em> </em><em>and the main thing is that we should provide education to the children and the youth and many </em><em>more</em><em>.</em><em> </em><em>if</em><em> </em><em>we are educated </em><em>we</em><em> </em><em>can</em><em> </em><em>stop</em><em> </em><em>such</em><em> </em><em>population</em><em> </em><em>growth</em><em>.</em><em> </em><em>so the main thing is that we </em><em>should</em><em> </em><em>stop population growth by giving </em><em>education</em><em>.</em><em> </em><em>Education</em><em> is the only one </em><em>way</em><em> </em><em>to</em><em> </em><em>stop</em><em> </em><em>such</em><em> </em><em>population</em><em> </em><em>growth</em><em>.</em>

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D
