Answer:
The correct answer is "Nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies".
Explanation:
Nitrogen fixing bacteria maintain a symbiotic relationship with plants. Bacteria performs nitrogen fixation providing the plant with ammonia, while bacteria has a safe place and nutrients to prosper. This relationship is very intimate because it occurs at the root hair of the plant at structures called nodules. Therefore, nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies

C. The rate of oxygen production is greatest in section M.
In the grassland trees and shrubs are rarely anywhere compared to the temperate forest. The animals don’t have a lot of shelter in the grasslands compared to the temperate forests.
<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!
Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.
Active Transport
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).
Phagocytosis
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.
Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.
Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>
Answer: ,Option B.
The Earth's axis has a 23.5 degree tilt.
Explanation:
The Earth axis of rotation is tilted to 23.5 degrees which is relatively to the orbital plane, this lead to differences in seasons of the places on Earth at a particular time. The angles varies overtime but moon gravitational pull prevent it from shifting more than a degree. There is different in seasons in the northern and southern hemisphere because at a time one part of it exposed to the Ray's of sunlight than the other which lead how the Earth's revolve round it's axis.
