Answer:
decreases
Explanation:
By 10% at each trophic level
As human travel increases the number of introduced species in a certain environment likely increases as well. When we're moving to certain locations, with us we're bringing millions of small bacteria and other living organisms that accompany us on our hands, different parts of our bodies and clothing. All of them perhaps were not present in locations that we visit.
Answer:
The statement is true.
Explanation:
The soluble nutrients from digestion (amino acids, sugars and soluble vitamins) travel from the intestine to the liver through the portal vein. The transport of lipids, cholesterol and fat-soluble vitamins is much more complex, since they are not soluble, they cannot be sent to the portal vein because there they would quickly produce fat deposits, and must be sent through the lymphatic system. Among the functions of the lymphatic system, two should be highlighted: its central role in the immune system, and its role in the transport of lipids and cholesterol from the diet. Lymphatic ducts from the intestine converge into the thoracic duct that joins the bloodstream near the entrance to the superior vena cava, where the lymph content passes into the systemic blood circulation.
Answer:
<u>cycle A is the lytic cycle and cycle B is the lysogenic cycle</u>.
Explanation:
In lytic cycle, the DNA of the host does not incorporate into the host genome but instead replicates using the resources of the host organism. In lysogenic cycle, the viral DNA is incorporated into the host genome and replication occurs without destroying the cell. In lytic cycle many copies of the virus are generated and the cell is destroyed.
Answer:
A.Energy available for use to the highest trophic level is small
Explanation:
As you go up in the trophic levels, only about 10% of the energy gets transferred from one level to the next. For example, the plants can only harvest 1% of the Sun's energy. The primary consumer can only absorb 10% of the energy from the plant he eats, so .1% of the total energy. The secondary consumer can only absorb 10% of the energy he get from eating the primary consumer, so .01%, and so on and so forth. As we climb up the trophic levels, there is less energy available and therefore less organisms.
