<span>The correct answer is A, B and D. Biogeochemical cycles are central to the ecology of earth system. They make the essentail elements accessible and available for the organisms, and maintain their levels, so that the ecology is ot disrupted. The elements move through abiotic and biotic factors, in these cycles, and a state of equilibrium is maintained n the ecosystem. The carbon dioxide levels are responsible fr the temperature of the earth. If Carbon cycles would not have existed, then there would have been a disruption in maintaining the global temperature. Biogeochemical cycles basically continuously recycles the essential materials, for sustaining the life-forms.</span>

Answer:

It ocurred a selection by allopatric speciation

Explanation:

The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.

It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.

So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.

Sauron [17]

Answer:

b) from a region of high pressure to a region of low pressure

Explanation:

Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick. Hence, blood flows from a region of high pressure to a region of low pressure.

Organisms breathe in air to their respiration processes.
Weather elements are conditioned by the atmosphere.
Decomposition of organisms release gases back into the atmosphere.

Can someone help me make a hypotheses?

egoroff_w [7]

Since a hypothesis is a statement rather than a question, you could simply restate the line given to you in line 1. (That is of course your hypothesis is on the subject of people and social media.)

If I were to make a hypothesis off of that subject I would use something along the lines of:

"People who use social media more than others are more likely to struggle with social skills face to face."

Hope this helps! :)
