Answer:
<em>The correct option is D) Hydrosphere</em>
Explanation:
The corals present int he hydrosphere interact with the algae through a endosymbiotic relationship. This endosymbiotic relationship helps to maintain the health of the corals and the reefs. However, at a certain time, the coral reefs might expel the algae living inside it. This phenomenon is termed as coral bleaching. The corals generally expel the algae when they are under stress situations such as changes in temperature or availability of nutrients.
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
<u><em>Age group</em></u><em>, </em><u><em>age graph</em></u><em> or </em><u><em>age scale</em></u><em> do not correspond to the population graph where the age and sex structure of a population are expressed.</em>
C. they are the same species and have different traits
Explanation:
When mapping the genome, it shows where other pests are more likely to appear. This means more control over the rate of pest growth, and they can stop reproduction from increasing.
Answer:
Option B, weight greater than your true weight
Explanation:
When a person stand on a scale in an elevator, his inertia tries to remain constant and stable. Thus when a lift starts moving upward it presses against the feet of that person in order to lift him/her up. In doing so an apparent weight is applied on the person which do not change with speed and it is due to this weight that scale shows a higher reading when elevator moves up.
Hence, option B is correct.
