Answer:
If two species have the same niche, one species will always move.
Explanation:
In biology, ecological NICHE refers to how the species of an organism performs in its ecosystem i.e. its role. Niche includes the reproduction, feeding pattern, prey, etc. However, if there are two species occupying the same niche, one species will always move.
One of the species, usually the weak one, will always move because occupying the same niche by two species will inevitably lead to competition, which causes one of the species to go elsewhere when these resources are limited.
If two species have the same niche, one species will always become extinct. This is known as the competitive exclusion principle. Hence option A is correct.
It states that two species cannot occupy the same niche in the same habitat and stably coexist. This is because they will compete for the same resources, and one species will eventually outcompete the other.
The only way for two species to occupy the same niche in the same habitat is if they have some kind of mechanism to prevent competition. For example, two species of birds may have different beak shapes that allow them to eat different types of food. This is known as resource partitioning.
If two species have the same niche and no mechanism to prevent competition, then one species will eventually become extinct. This is because the species that are better adapted to the environment will outcompete the other species and eventually drive it to extinction.
Therefore, the correct option is A.

convection, conduction and radiation is the correct answer because heat flows from hot to cold. The heat flows from hot objects to cold objects whether the heat transfer is occurring by convection, conduction, or radiation. Heat flows from warmer substances to cooler substances until they reach the same temperature.
B. broad, flat leaves
C. stomata for gas exchange
D. xylem vessels for water transport to the leaves. E. All of these are adaptations for photosynthesis.
Answer:
I think it's (E) but I'm not sure
B. Position P
C. Position N
D. Position O
Position P indicates the location of moon during a lunar eclipse. Hence, the correct statement is option B.
A lunar eclipse is a celestial event that occurs during a full moon phase when the Earth passes between the Sun and the Moon, thereby, casting its shadow on the Moon which makes the moon a reddish-brown or coppery color, hence the moon is called "blood moon" during lunar eclipse.
A lunar eclipse only occurs when the Moon is in full phase and aligned with the Earth and Sun and can be visible from anywhere on the Earth. The lunar eclipse can last for several hours.
During a lunar eclipse, when Earth passes between the sun and the moon, it casts its shadow on the moon. The point at the moon's orbit where it is passing through the Earth's shadow is represented by position P which results in lunar eclipse.
Therefore, Position P indicates where the moon would be located during a lunar eclipse.

Answer:
B. Position P
Explanation:
If it is at "Position P", the Earth blocks the moon from the light from the sun, creating an eclipse.
