2. During the sexual portion of the Plasmodium cycle spores formed in the human host are released into the bloodstream which is usually picked up by an uninfected female anopheles mosquito when it takes a blood meal.
3. An infected mosquito passes the sporozoites to a new human host when it takes a blood meal and the cycle starts all over.

The position of the Earth in the solar system and more regional effects, such as carbon dioxide levels, all play a role in the causes of ice ages. Thus, option A is correct.
<h3>
What are factor that involve in ice age on earth?</h3>
When the orbital cycle turns back, these feedbacks—involving the spread of ice and the emission of greenhouse gases—work in reverse to warm the Earth once more.
A prolonged period of cooling of the Earth's surface and atmosphere is known as an ice age, which is marked by the development or presence of polar and continental ice sheets as well as alpine glaciers.
Flooding has increased along the U.S. coastline as a result of the warming, rising, and acidifying of the seas.
Therefore, The Earth is currently facing an ice age.

First answer is correct. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
