Answer:
If a plant cell is placed in distilled water, water will enter the cell and the cell contents will expand. However, the elastic cell wall exerts a back pressure, which will limit the net gain of water.
Explanation:
Genetically modified human isn't normal. The reason for this is that they are changing the original genetics of the human body. Even though genetically modified humans can have benefits, it also can have bad consequences.
Answer: The more active cells produce more carbon dioxide.
Explanation:
When the cells are constantly working the amount of oxygen consumed and more amount of carbon dioxide is released by the cells.
Chemo receptors in the circulatory system increases the ventilation so that more carbon dioxide can go out of the cell and more oxygen can get inside the cell.
This is because the more active cells more carbon dioxide and there is a sudden increase in the concentration of carbon dioxide which need to be corrected by the help of ventilation.
Answer:
B) 300
Explanation:
There are two types of alleles present for wing type in this population of Drosophila, c and c+. Various combinations of these two alleles will produce different phenotypes.
c+c+ : straight wings = 45
c+c: straight wings = 70
cc: curly wings = 35
Total flies = 150
Each fly has one gene with two alleles for wing type. Hence 150 flies will have 300 alleles in the gene pool.
