Answer:
True.
Explanation:
Antigen may be defined as the chemical that has the ability to evoke the and immune response and can harm the living organisms. The specific antibody are produced against the immune response.
The antigens has evolved different mechanisms to prevent themselves from them the immune system of the host. The antigenic shift is the most common change that might occur in viruses that helps the antigen to protect itself by changing its genetic material. No anti viral drugs are available for the viruses.
Thus, the answer is true.
Answer:
Point mutations are a broad category of mutations that describe a change in a single nucleotide of DNA, such as a substitution for another nucleotide, deletion of a nucleotide, or insertion of a single nucleotide into the DNA, resulting in DNA that differs from the normal or wild type gene...
or you can say:
Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene ...
Answer:
The frequency of the sound.Hope this helps btw
Explanation:
You would need to know how fast the sound waves go through the air.
Altitude affects weather determines how dense the air is and how much heat energy the air can hold.
Option C is the correct one.
<h3>What is the relationship between authority and climate?</h3>
The relationship between climate and altitude is manifested through variations in atmospheric pressure and temperature. Although higher locations are closer to the sun, they tend to receive less heat, becoming colder, in addition to having a smaller thermal amplitude (temperature variation).
With this information, we can conclude that Higher elevations cause temperatures to drop because the higher up in the atmosphere you go the colder it gets due to air pressure in turn causing precipitation to freeze creating snow.
