If enough ejecta (mainly ash) is sent into the upper atmosphere, the dust particles will block solar energy causing a decrease in temperature. This has happened in the past. Look for the year without summer caused by a volcanic eruption.
Answer:
Unlike inbreeding, hybridization is more likely to cause genetic abnormalities.
Cholesterol in Cell membrane strengthens and helps to maintain the fluid nature of a cell regardless of temperature
<u>Explanation:</u>
All organisms are made up of one or more cells. Each cell is protected or differentiated by a covering called as the cell membrane. Phospholipids are the basic structure of the cell membrane. Cholesterol prevents the loss of fluid from phospholipids.
Cell membrane has a lipid layer and cholesterol which is placed between the phospholipids to maintain the fluid nature of the cell under different temperature. Cholesterol prevents the cell from solidifying and helps maintain the fluid. Cholesterol actually acts as a buffer between different temperatures.
Generally geyser field sites are located near active volcanic areas
Options are not provided in the question. I found the answer on the Internet.
Yes, deletion of the possible control elements can cause reduction in reporter gene expression. Due to deletion of a control element, the activator cannot bind to the enhancer. This causes reduction in the gene expression.
Answer: Deletion of element no. 3 causes a reduction in reporter gene expression.
