How does the overuse of fertilizer produce algal blooms in bodies of water far from the source of the pollution? a.Excess carbon dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
b.Excess oxygen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
c.Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.
d.Excess hydrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.

Answers

Answer is (c). Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.

The fertilisers contain urea which is a Nitrogen based compound. The use of fertilisers in farms leads to the water run offs carrying the excess amount of it to the nearby water bodies. The algae in the water bodies require Nitrogen to synthesise the proteins needed for their growth. The increase in the dissolved Nitrogen in the water bodies due to the run off boosts the growth of algae by fulfilling their requirements.

Which is an advantage of flowering plants?A. Flowers attract insects that transport gametes
B. Flowers give greater access to sunlight
C. Flowers help transport water and nutrients
D. Flowers assist plants that live in the water

What is the advantage of the flowering plant?

Because they are often showy and endowed with nectaries, the flowers of angiosperms attract animals, such as small invertebrates, birds and bats. Such living beings, when coming into contact with several flowers of the same species, provide the meeting of pollen grains with female reproductive structures.

Flowers help to maintain air quality. They are natural humidifiers purifying the place and releasing oxygen. They also work as aromatizers by exhaling their fragrances.

The platypus has fur like other mammals
B. The platypus lays eggs like a reptile.
C. The platypus does not have fins like a fish.

Answers

The additional information required is that the platypus lays eggs like a reptile.

What are mammals?

The animals classified as mammals are those animals that give birth to their young ones alive and also possess the mammary gland. As such, they can breast feed their young ones.

Since the mammals share a similar ancestry as the reptiles, the additional information that Julia requires is that the platypus lays eggs like a reptile.
