Answer:
<u><em>PROPHASE</em></u>
Explanation:
The first stage in Meiosis I is prophase I. During this stage the DNA condenses into chromosomes. During prophase I, homologous chromosomes pair up and exchange sections of DNA. This is called recombination or crossing over
It would be Detroit because in fall u would have cloudy skies
Answer:
Lysosome
Explanation:
The lysosome is surrounded by a single membrane. This membrane made up of lipoproteins. The lysosome is also known as a suicidal bag. This is meant for the digestion of injured cells. The acidic enzymes present in it helps in cell lysis. The cytoplasm burst due to osmotic swelling. If a single lysosome will burst in the cell it won't affect the cell. When several lysosome bursts together it can rupture other cellular organelles. It is fatal for a cell.
The predominant hypothesis for why the animals needed some 3 billion years to evolve after the life first appeared on the planet is that the conditions were not right for them to appear.
The life on Earth has appeared much earlier that what we normally assume, and also it has not been evolving very quickly, but instead it has been a very slow and gradual process. The reason for that is that the living conditions on the Earth were much different than what are they now, or anytime from the Cambrian period until the present.
The surface was still pretty hot, and there was intense volcanic activity. The composition of the atmosphere was not suitable for animals to appear at all, and in fact it would have been toxic for them. The water too had chemicals in it that were not providing the right conditions for animals to evolve. It was only after the plants started to appear and managed to make lot of changes in the water, atmosphere, and land, than the animals were able to evolve and develop.
