The dependence of the cheetah population on the gazelle population for food shows a kind of interdependent interaction.
What are interdependent interactions?They are a form of interaction between two organisms in which the survival of one is dependent on the other.
If the organism whose existence is important to the existence of the other should go extinct, it will greatly affect the survival of the latter.
Aside from going extinct, the rise and fall of one of the organisms affect the other either positively or negatively as well.

How might an environment be affected if humans introduce a new type of plant to the environment? A. The plant may compete with other plants for light. B. The plant may become another food source for animals. C. The plant may be poisonous and harmful to animals. D. all of these
Answer:
D. all of these
Explanation:
The reason is because all of the above are TRUE.
A. The plant may compete with other plants for light.
It feels like Plants and Trees are just stuff growing, but they actually compete with other plants, some don't do that much, but some do that, so that new plant may do it to get more light and might put more shade on other plants, which is dangerous for other plants.
B. The plant may become another food source for animals.
This is pretty normal, I mean, the thing here is that any plant is vulnerable to being eaten by an animal.
C. The plant may be poisonous and harmful to animals.
Yeah, like in choice B, the same thing, the plants are always Vulnerable to be eaten by hungry animals, and if an animal eats it... then it might get a disease or might just die.
So if these are all correct, then the answer HAS to be D. All of these
Answer:
D. All of these
(P.S. I got it right on Study Island)
Explanation:
When humans introduce non-native species to an area, there are many possible effects.
If a plant were introduced to an environment,
the plant may compete with other plants for light.the plant may be poisonous and harmful to animals.the plant may become another food source for animals.What does X represent in this model?

olfactory cells and taste buds are normally stimulated by ________.
Answer:
The answer is substances in solution.
Explanation:
Olfactory cells and taste buds are normally stimulated by substances in solution.
Olfactory cells are normally stimulated by odorants, which are chemical substances that are volatile and capable of being detected by the sense of smell.
Taste buds, on the other hand, are normally stimulated by tastants, which are chemical compounds that can be tasted. Tastants include various molecules such as sweet, sour, bitter, salty, and umami compounds.
Both olfactory cells and taste buds play crucial roles in our perception of smell and taste, respectively, and they are stimulated by specific chemical substances that interact with receptors present in these sensory cells

Pls helpthe sun hits the ocean at the equator more directly than at the poles. how does this support the flow of currents in the ocean?
The Sun creates a lot of thermal energy in the atmosphere and the oceans. Currents created as warm equatorial waters move to the north carrying heat. Due to this, the cold polar waters go south, and there get heated.
What is thermal energy?Thermal energy refers to the energy within a system and is responsible for its temperature.
The Sun heats up the air at the equator. This air will move toward the poles and cools down there with time.
In this process, the wind that occurs due to air currents will induce currents at the ocean surface.
The currents at this surface are propagated down deeper due to the differences in the forces on different parts of the water.
Thus, It is the main reason that the sun hits the ocean at the equator more directly than at the poles.

3. In science, a theory is more like a scientific law than a hypothesis. A theory
explains a set of observations or events. It must be verified multiple times by
many different scientists. One scientist cannot create a theory on his or her own.
a) Look back at your hypothesis from question 2. Could this hypothesis become
a theory if you repeated your experiment 100 different times and got the same
results? Can a theory be created by just one person? (2 points)
Answer:
No
Explanation:
A theory cannot be made by one person, no matter how many times they repeat the experiment. Therefore, you repeating the experinment does not make it a theory. The experinment must be repeated by others and get same result as you to confirm it as theory.
