Ответ:
1. The flexibility of the plasma membrane allows bacteriophage and increases mobility in pursuit of invaders.
2. Beta cells put out chemical antigens to eliminate invaders chemically.
3. Various white cells display proteins on their plasma surfaces to communicate the composition of the pathogen.
4. White cells (unlike red blood cells) have a nucleus, which allows the synthesis of new chemicals in response to various invaders.
5. White blood cells tend to have a higher surface to volume ratio than other cells because the are more amorphous. That would lead to a relative increase in the plasma membrane, which contains receptors for identifying.antigens. The white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration.
Ответ:
Carbon dioxide and oxygen are differentially exchanged between the atmosphere and the oceans in the carbon cycle. An increase in atmospheric carbon dioxide also raises the carbon dioxide absorbed by the oceans. This increases the pH of the ocean waters which consequently affects the growth of phytoplankton. Low pH affects negatively the growth of phytoplankton. The clarity of the waters would, therefore, increase with pH due to low plankton growth.
