Predator and prey often adapt to their ecosystem in different ways to increase their chances for

Answers

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.

At what age can female mice breed?
Only answer if you have experience in this subject!
Will give brainiest!

Answers

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.

Answer
F
sodium

G
glucose

H
polysaccharide

J
potassium

Answers

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.

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

Answers

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.

Answers

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.

What is a carbon cycle?

It is a biogeochemical cycle by which carbon is exchanged among various spheres of the Earth.
