Answer:
The mouse CFTR gene and human CFTR gene encode proteins that can serve a similar function.
Explanation:
CFTR (Cystic fibrosis transmembrane conductance regulator) gene that codes for the membrane protein. This gene is responsible for the transport of the chloride ions in the cell.
Any mutation in CFTR gene can cause the lung diseases in individual. As shown in the experiment the mouse gets normal when given normal human CFTR gene. The CFTR gene plays the similar role and function in both huamn and mouse.
Thus, the correct answer is option (C).
The chickenpox virus is a highly contagious disease that can cause itchiness and produces a blister-like rash. It is caused by the varicella-zoster virus (VZV).
1. Varicella-zoster virus has the ability to switch from a latent lysogenic cycle to an active lytic cycle that reactivates after dormancy.
2. Varicella-zoster virus infects human cells. Basically, it infects and replicates the cutaneous fibroblast and epidermal cells and the several types of immune cells.
3. The person typically contracts this virus through inhalation. It enters the host's respiratory tract where it replicates in the nasopharynx as well as the regional lymph nodes.
4. This virus is characterized by red itchy blisters that can spread over the entire body.
What brought the beginning of the earth
Answer:
Build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams.
Explanation:
<u>Building dams would help in generating hydroelectricity and reduce floods. Using cars that emit fewer harmful gases would help in controlling pollution and global warming. Factory waste drained into streams and rivers pollutes the water and is dangerous for aquatic plants and animals. Hence, halting the runoff of factory waste into rivers and streams would save water pollution. Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources</u>
