Answer:
Option D When activated, Bax and Bak form oligomers in the outer membrane of mitochondria, leading to the release of cytochrome c.
Explanation:
The proapoptotic genes are involved in the process of apoptosis. The antiapoptotic gene prevents apoptosis that is cell death. The proapoptotic genes are bax, bak, bad and bid. The bcl family genes are antiapoptotic genes. The process involved activation of apoptosis inside the cell is called intrinsic pathway of apoptosis.
The activation proapoptotic genes, Bax and Bak form oligomers in the mitochondria outer membrane. These pores in the mitochondrial membrane allows the release of cytochrome-c that further attaches with Apaf-1. This leads to activation of caspase 9 that further activates caspase 3, thus inducing apoptosis.
<span>Trophic level—90% of energy consumed at trophic
level is used by the consumer for survival and reproduction. The remaining 10%
is transferred to the next trophic level. So the answer is 10,000 x 0.9
or 9,000 calories will be generally available

Answer: c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
Explanation:
Deep-sea hydrothermal vents are hot spots of geothermal water. The organisms living in deep-sea vents cannot obtain energy from sunlight. They are dependent on chemosynthesis, which involves the utilization of inorganic substances to produce organic substances, which allows their survival and act as a source of energy. In the given situation, bacteria present on the surface of mussels are capable of chemosynthesis also the mussels are dependent upon inorganic hydrogen in seawater. Thus chemosynthesis supports the survival of organisms living in the deep sea vents.
If a drug controls blood pressure than the transport of materials throughout our body will be affected. As for example - gases exchange, hormone level of every organ will be affected most. organs can develop hypoxia or hyperoxia conditions which can lead to cell damage or malfunction inside the organ and that can have a lethal effect on body also.
