Since it is the hearts job to pump blood throughout the body of the organism, the circulatory system would fail and the entire organism would suffer if the heart cells stopped working properly.
<span>Plant cells will also change with the degree of specialization. It means that when is is a higher developed organism then it will have a higher degree of specialization. For the second question,Somatic cells of animal callus are most common to the plant cell. It is because just like a callus, the tissue of the plant cells are thick and it serves them as protection from friction.</span>
The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.

I live in letter D in summer and letter B in winter.
<h3><u>Explanation:</u></h3>
In the diagram the letter D represents the summer solstice and the letter B represents the winter solstice. But the letter A and C represents the equinoxes that are present in the month of March and September. Here in India the country lies above tropic of Cancer. So the condition here is like the temperate region. So during summer the sun's rays directly fall on the country as well as during winter the country receives oblique sun rays. Thus from the diagram we can see see that the letter B represents the condition of earth when the sun's rays are not directly falling on earth. So it's winter solstice .
In the letter D we can see that the earth is going through the summer solstice because sun's rays are directly falling on the earth. So it's summer at that time.
