Answer:
A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.
Explanation:
Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.
The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.
If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
Answer:
do you have the rest of the answers? i really need them.
Explanation:
Experiments with faulty design or inconsistent data:
-decreases the experiment's reliability and validity
- wastes time and resources
- destroys the scientist's credibility in their field
- may lead to issues of safety to the experimenter/s due to faulty design
- is discouraged especially in hard sciences where data obtained should be accurate and precise
Explanation:
There are many<span> reasons that experiments with faulty </span>styles<span> or with incorrect </span>knowledge are<span> problematic for scientists. One reason for them to be problematic </span>is that if<span> he or she were to poorly </span>live<span> what </span>they're learning<span>. </span>as an example<span>, </span>somebody<span> measured the mass of a book </span>properly<span> to be </span>two<span> pounds, and </span>somebody else<span> measured it </span>erroneously<span> to be </span>one<span> pound. </span>differently<span>, that faulty designed experiments and inconsistent </span>knowledge will be<span> problematic is lack of accuracy and </span><span>exactness.</span>
If one parakeet is heterozygous, that means it has one dominant gene and one recessive gene (Rr). If the other is homozygous for white feathers, then it has two recessive genes (rr). Crossing these two in a punnet square gives you 50%.
