Answer:
The proteins are expressed differently in each cell.
Explanation:
<u>The correct answer would be that the proteins are expressed differently in each cell. </u>
The regulation of gene expression is primarily responsible for differential functions of the same DNA sequence. Multiple proteins are formed from the same DNA sequence but only the required ones are specifically expressed depending on the cell.
<em>In other words, in the blood cells, the protein is expressed for performing blood-specific functions while it is expressed for performing skin-specific functions in the skin.</em>
Answer:
C. causes cell lysis
Explanation:
The slow release of the bacteriophage progeny from a bacterial host cell causes bacterial cell lysis and further kills the host cell which is the bacteria, this results to the liberation of progeny viruses which then infect new bacterial cells.
Only a type of bacteriophage called the filamentous bacteriophage reproduces without killing the bacterial host cell. The filamentous phages infect majorly gram negative bacteria.
Explanation:
Fracking is the introduction of substances into a formation in order to increase they pore pressure and to increase natural drive of hydrocarbons.
Fracking has several environmental issues associated with it;
- Fracking leads to air pollution in case of blowout of gas pressure in formations, particles and dusts can become blasted into the environment.
- Proppants in fluids channeled into formations can lead to ground water contamination.
- In areas where fracking is done, there might be an exposure to harmful chemicals.
- Destruction of the natural habitats of animals.
The correct answer is: cerebral cortex (prefrontal).
Cerebral cortex is the outer layer of cerebrum and it is the neural integration area of the brain. Globally, the role of cerebral cortex is role in memory, attention, perception, awareness, thought, language, and consciousness.
Prefrontal cortex is part of the cerebral cortex (cover the front part of frontal lobe). It is involved in complex social behavior of the human, complex cognitive behavior, decision making.
