A is the stimulus. Stimulus is a response, and the plant growing toward the light is a response. So, the answer is A.
So In the interest of time I'm just gonna have the flower part and the function directly beside it.
The parts and their function are as follows:
<span>1. Pistil - female part of the flower {consists of the stigma style and ovary}
2. Stamen- makes pollen {consists of the anther and filament and the anther
is responsible for pollen production}
3. sepal- </span>protects the ovary {at the base of the flower on the outside of the ovary and acts as a second layer there}<span>
4. receptacle- </span>attaches the flower to the stem {a stem like structure below
<span> the ovary connecting the flower to a main stem.}
5. petals- </span>attract pollinators {in animal pollinated flowers, the petals are colorful
and sweet-scented thus attracting bees
and birds that will help the pollen get from the
anther to the stigma}
Explanation:
The chlorophyll's donated electrons need to be replaced, and these electrons come from the splitting of water. In a process called photolysis ('light' and 'split'), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.
B. The brain reacts to excessive dopamine levels by increasing the number of dopamine receptors.
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.
