Answer:
B) Air Resistance
Explanation:
A reaction force is the opposite of an action force, so what is opposing gravity? Momentum certainly isn't in this instance of the apple falling. Thermal velocity isn't, and anti gravity is a hypothetical phenomenon.
The correct answer is D. Mine claim
Explanation
Mine reclamation is a technique for restoring areas that had been exploited previously by mining activity. This technique gives new use to the land once all minerals are extracted to revitalize the old mine that has left with some damage after it. In general, in these spaces are established recreation and leisure places for people like amusement parks. In other cases, Mine Reclamation promotes the creation of natural ecosystems for birds and other animals. Due to the above, it is correct to affirm that this technique was put into practice in the Six Flags park in San Antonio because the place where there was a mine, another place was established giving new use to this land. So the correct answer is the D. Mine reclamation.
Answer:
b. benefit ... harmed
Explanation:
Predation is a relationship that occurs between two organisms dwelling in a biological community, in which one of the organisms (predator) obtains their food by killing and eating the other (prey).
This biological interaction is a winner-loser relationship where the prey is harmed, while the predator benefits. For example: lion and zebra relationship. The lion kills and eats the zebra. The lion benefits, while the zebra is harmed.
-The number of B cells producing the antibody is proportional to the concentration of that antibody.
-On day 16, one out of 100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells
- on day 16, Antibody concentration is 2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000
20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x
x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>
