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.
Answer:
Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton
Explanation:
I'm not sure, but I think the answer might be false, because I'm pretty sure you can feel if someone or something is pressing down on your leg or arm.
Answer:
The preferable option will be - B.
B. juxtaglomerular complex.
Explanation:
The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus.
</u>
The given options were -
a. nephron loop (loop of Henle).
b. juxtaglomerular complex.
c. renal corpuscle.
d. filtration membrane.
e. afferent arteriole.
- The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.
The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
