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:
leaves more viable offspring than others of its species
Explanation:
Greater fitness is being conferred on an individual organism compared to the other individual member of a species population if that individual does not only just competes favorably for the limited resources available than the rest individuals, but is in fact able to reproduce more rapidly and thereby pass on such favorable traits, which makes them better competitors, to as many of their offspring as possible. Over time, you will find most of the offspring they leave behind more common in the population than the other.
If an individual organism is referred to as having a greater fitness compared to another individual of the same species, what it simply means is that the organism <em>leaves more viable offspring than others of its species</em>.
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
The speed of barrel is 3.6 m/s when moving from one flag to another.
For calculating the speed of the barrel from one flag to another, we used the formula of speed which is speed= distance / time. We know that the distance between two flags is 100 meters.
The time taken by the barrel from one flag to another flag is 28 seconds i.e. subtracting 2:43 from 2:15 we get 28 seconds. By putting the value of distance and time in the formula of speed we get 3.6m/s so we can conclude that the speed of barrel is 3.6 m/s when moving from one flag to another.
