Answer:
A algal bloom causes the dissolved oxygen level to decrease.
Explanation:
It does mot allow the oxygen from atmosphere to dissolve into the water moreover it blocks the sunlight to reach to the sea plants that produces oxygen by photosynthesis.
The algal blooms affect a body of water by decreasing the level of dissolved oxygen. The correct option is D.
What is an algal bloom?An algal bloom is an increase in the number of algae in the water bodies. These blooms in large quantities and are poisonous to humans, and the organisms present in the water bodies.
The algal bloom decreases the amount of dissolved oxygen, and the water organism suffers from this.
Thus, the correct option is D) Algal blooms cause dissolved oxygen levels to increase.

Which method best helps to prevent wind erosion?
rotating crops
decreasing riverbank slopes
growing more vegetation
avoiding soil compaction
Answer:
Growing more vegetation
Explanation:
Soil erosion by wind occurs anywhere when vegetation and climatic conditions are conducive. These conditions include presence of very strong winds and when the soil is loose, dry, and is composed of fine granulated particles.
It also occurs when the soil surface is relatively smooth and there is sparse or no vegetative. It can also occur where there are large fields with no windbreak mechanisms in place.
The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. This involves growing of more vegetation, either cash crops or cover crops which serves to protect the soil and keep the winds higher off the surface.
Also trees can be planted around the farms to serve as wind breaks which breaks or reduces the force of the winds.
Also, soil compaction which is the process of increasing the density of soil by packing the soil particles closer together causing a reduction in the volume of air can help to prevent wind erosion.
From the given options above, the best option would be growing more vegetation.
Practicing crop rotation serves to preserve soil nutrients and prevent diseases.
Decreasing riverbank slopes prevents erosion by water.
Avoiding soil compaction would lead to more erosion by wind.

ully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. The total mass of the snowmobile, including Sully, is 280 kilograms. If Sully accelerates to a velocity of 16 meters/second over 10 seconds, what’s the force exerted by the snowmobile to accelerate? Use F = ma, where .
Answer:
168 Newtons.
Explanation:
The computation of the force exerted is shown below:
Since the sully accelerated for a velocity of 16 m/s over 10 seconds
So the excess would be
= 16 - 10
= 6
And, the ratio of change in velocity is
[tex]= \frac{6}{10}[/tex]
= 0.6 m/s
Now as we know that
[tex]f = m\times a\\\\ = 280\ kg \times 0.6[/tex]
= 168 Newtons
Hence, the force exerted is 168 newtons
We simply applied the above formula so that the force could arrive

It kills the animal and feeds on its carcass. C.It releases spores into the animal’s digestive tract. D. It produces eggs that are shed on the ground with the animal’s wastes. brainliest to the correct answer
Answer:
A. It uses the animal’s cellular machinery to reproduce inside the animal.
Explanation:
I would go with A because since it is a virus it cannot live outside the body and thus needs to rely on host's cell for metabolism as viruses are not capable of having their own metabolism.

A. The partially positive charge on the oxygen of one molecule
attracts the partially negative charge on the hydrogen of another.
B. The partially negative charges on the oxygen atoms of two
different water molecules are attracted to each other.
O c. The partially negative charge on the oxygen of one molecule
attracts the partially positive charge on the hydrogen of another.
D. The partially positive charges on the hydrogen atoms of two
different water molecules are attracted to each other.
SUBMIT
Answer:
C.
Explanation:
Water is made up of H20. Hydrogen has a positive charge, and oxygen has a negative one, so the water molecule is polar(meaning it has an unequal sharing of electrons). Anyway, when water molecules connect, opposites attract, so the hydrogen(positive charge), is attracted to oxygen(negative charge). This is referred to as a HYDROGEN BOND, and isn't a bond, but an attraction. It allows for all the properties of water, which are essential to life. I could go on, but I don't want to put you to sleep.
what kind of cells can develop from pluripotent stem cells?
Answer:
Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.

scientific research about the carbon cycle and global warming would be most valuable if the results
Answer:
if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.
Explanation:
As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.
In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.
