Answer:
Algae Blooms
Explanation:
When soil is eroded and taken to other locations, the nutrients it carries are taken with it. If these nutrients make their way to ponds or lakes, they can support rapid reproduction in algae, creating algae blooms that can damage local ecosystems.

Marine ecosystems support a(high, low) diversity of life,
largely due to (constant unchanging conditions, a lack of natural predators, the variety of environments) throughout the ocean.
Answer:
high diversity, variety of environments
Explanation:
To this day, scientists are still discovering new marine animals. This is because of all of the different environments in the ocean, Some animals exist in tropical areas, others in freezing cold water. Some animals even exist solely in high pressure areas that are hundreds of meters below the surface. There are even organisms older than dinosaurs living in the ocean.
Which macromolecule has an amino acid as its monomer?
Answer:
Proteins
Explanation:
Predator and prey often adapt to their ecosystem in different ways to increase their chances for
Answer:
Because predator species often will switch its prey as one prey species becomes less abundant.
Why this is so should be obvious - because it's not in the interest of predators for the prey species to completely die out as it would effectively also mean that they would die out due to not having enough food to eat.

What is the best way to breed mice?
At what age can female mice breed?
Only answer if you have experience in this subject!
Will give brainiest!
Generally, putting one male with two females in a single cage will increase the chances of breeding. To prevent fighting, it's important that there's only one male in each cage. If you're not sure which mice are male, gently lift them up by the tail and look between their legs. Most mice reach sexual maturity (males and females) at 4-7 weeks of age. Younger mice generally produce smaller litters and therefore are not typically mated until they reach 6-8 weeks, of age. Mice that have been housed alone or in same-sex pairs will usually not breed successfully if they are older than 6-8 months.

Are brown eyes healthier than blue eyes?
Answer/Explanation:
Blue eyes have less melanin than brown eyes. Melanin helps vision and hearing. It also affects behaviors and balance.
This means Brown eyes are healthier than blue eyes.
Studies have shown even for cats that if they have white fur and blue eyes(lack of melanin) that they would have a 90% chance of being born deaf.
SCIENCE QUESTION
Chloroplasts are organelles found only in plant cells. Why are chloroplasts not needed in animal cells?
Animals have bones for support and don't need rigid chloroplasts to provide structure.
Animal cells store DNA in the nucleus, not in chloroplasts like plants
Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.
Animals obtain energy from eating other things, not from photosynthesis.
Answer:
Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.
Explanation:
Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.
Answer:
Explanation:
1:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

If competition for resources and space is high, the less efficient organisms will most likely experience a drop in population, but if the competition for resources and space are low, the population will have the capability to rise.
What is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (Formula:)
a) 25 J
b) 5 J
c) 50 J
d) 100 J
Answer:
a) 25 J
Explanation:
Formula for kinetic energy= 1/2(mv^2)
where m(mass) =0.5kg
v(velocity) =10m/s
Therefore, Kinetic energy= 1/2(0.5*10*10)
KE =1/2(50)
KE =25 J

Explanation:
Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below.
Her friend Byron evaluates the model and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them.
Label the model to show where it represents photosynthesis, cellular respiration, and the burning of carbon-containing materials.
Answer: in the upper box on the black arrows above the forest is photosynthesis and on the other one in that same circle is cellular respiration. Burning goes on the longest white arrow that goes from fossil fuels.
The labelling of the model is in the image.
The Model describe the carbon cycle in which there is a diagrammatical representation of how carbon is exchanged among the biosphere, hydrosphere, geosphere and atmosphere.What is a carbon cycle?
It is a biogeochemical cycle by which carbon is exchanged among various spheres of the Earth.
It shows the nature's way of reusing carbon atoms, into organism in the Earth and then back to the atmosphere over and over again.To know more about carbon cycle here

Which of the following substances must be taken into the cell by the structure above labeled 3 because it is too large to pass through the cell membrane?
Answer
F
sodium
G
glucose
H
polysaccharide
J
potassium
Answer:
I think it's polysaccharide because it is made of 3 or more units of sugar
The substance polysaccharide must be taken into the cell by the structure above labeled 3 because it is too large to pass through the cell membrane. Thus, the correct option is C.
What is the cell membrane?A Cell membrane may be defined as a biological membrane that typically separates the inner environment of the cell with respect to the outside. It generally protects the cell from any external damage.
Being very large organic compounds, polysaccharides take large space to pass through the cell membrane. Polysaccharides are made up of three or more subunits of sugar.
The elements like sodium and potassium usually occur due to the presence of sodium-potassium pumps. While glucose is transported into the cell with the help of glut transporters.
Therefore, the substance polysaccharide must be taken into the cell by the structure above labeled 3 because it is too large to pass through the cell membrane. Thus, the correct option is C.
