What is combustion and how does it affect the carbon cycle

Answers

Combustion is the burning of fossil fuels such as coal, natural gas, oil, etc. It affects the carbon cycle because it adds much more carbon to the air. That then causes phenomenon's like global warming. Therefore, it is bad for our environment and ozone layer.

Do predators really kill only the old and sick prey? What evidence is there for this statement

Answers

There are many factors that determine what a predator will prey on. For instance if the predator is starving or if they are hunting in a pack. Predators will usually prey on animals that are easiest to be captured without using too much energy. The sick, young, old, small and unaware animals will often times fall prey since they are easiest to be caught. Predators don't necessarily prey only on the ill/ injured. Sick prey may be overlooked because their bodies may not provide the necessary sustence for the predator and others it may be feeding. Healthy large slow moving animals may be difficult to kill but the payoff is greater, especially if a pack is involved.

Final answer:

Predators do not only kill old and sick prey. They can also target healthy prey depending on factors like population dynamics and resource abundance.

Explanation:

Yes, predators do not only kill old and sick prey. Predation is a complex interaction that involves predators hunting and consuming prey. While predators may target weaker and more vulnerable individuals, they can also target healthy and strong individuals if necessary.

One example of this is the cycling of predator and prey populations, such as the lynx and snowshoe hare. As the hare population increases, there is more food available for the lynx, allowing its population to increase as well. However, when the lynx population grows too large, it can kill a significant number of hares, leading to a decline in the hare population due to scarcity of food.

Therefore, predators can kill both old and sick prey as well as healthy prey, depending on various factors such as population dynamics, abundance of resources, and competition.

The _______ the time period during which a species lived and the _______ the distribution of its fossils, the better an index fossil the species is. shorter; narrower shorter; wider longer; narrower longer; wider

Answers

The index fossils have a shorter time period and wider geographical distribution of fossils.

What is an Index fossils?

An Index fossils refers to class of fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time.

They helped in the construction of geological periods that are commonly used today.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Therefore. the Option B is correct.

Answers

C. It destroys red blood cells.

Answer:

C. it destroys red blood cells

Explanation:

When Plasmodium sporozoites enter the body, they infect the liver. New cells called merozoites emerge from the liver and infect red blood cells. The merozoites eventually burst from the red blood cells, destroying them and releasing toxins that cause various symptoms.
