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
It can prevent colon cancer lol
All other organs, ducts, and glands in the reproductive system are considered secondary, or accessory, reproductive organs. These structures transport and sustain the gametes and nature the developing offspring.
Hope this helps!
Answer:
C. Most people will die from negative health effects associated with stroke as indoor dirty air builds up.
Explanation:
<u>C is correct option</u> because it shows the highest proportion of people's death caused by stroke. On the other options are not correct due to the following reasons:
A is incorrect because it says that people have a lower risk of dying from COPD. On the other hand, the graph shows that this is 3rd most abundant cause of deaths.
B is incorrect because deaths due to lung cancer are the lowest according to the graphical illustration.
D is incorrect because the proportion of developing acute lower respiratory infection and ischemic heart disease are not the same. Deaths due to ischemic heart disease are higher than the acute lower respiratory infection.
Answer:
5 moles of ammonia would be formed.
Explanation:
Given data:
Moles of NH₃ formed = ?
Moles of H₂ react = 7.5 mol
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of ammonia with hydrogen.
H₂ : NH₃
3 : 2
7.5 : 2/3×7.5 = 5
5 moles of ammonia would be formed from 7.5 moles of hydrogen.
