Mitosis is responsible for the growth and repair of human tissue. Mistosis is just a fancy word for cell division
Due to resource partitioning, zebra relative density changes over time and grass height.
<h3>What is resource partitioning?</h3>
- Resource partitioning is the process by which due to natural selection, competing species use different resources and niches.
- In the case of African savanna, right after peak rain all the three grazers (zebra, wildebeest, and Thomson’s gazelle) have high density.
- After rain in one month relative density of zebras is maximum but it becomes nearly zero after three months due to high density of wildebeest and then increases a little after six months.
- The density of zebras is greatest when the grass is tallest and most abundant because of resource partitioning as zebras get the most out of eating tall grass.
- Zebras can eat and digest faster taller grasses with many stems.
- This gives them an advantage over other grazers in terms of nutrition when the grass is tall.

Answer and Explanation: <em>You will find the graph in the attached file</em>
When changing the numbers in the vertical axis of the original graph, you will see that bars tend to get shorter than they originally were. This occurs because new numbers are much bigger than the original numbers, the proportion of the bars changes because they must represent the same information in a much bigger space. Offenlly, this is a tool very used by media to mark a tendency when informing something. So It is very important whenever looking at any graph to see what the axes are telling you because by the size of the bars you might infer something that might be different from what is really going on.
Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.
The two different types of stem cells broadly classified as are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.
Explanation:
Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.
Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.
The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.
