Answer:

The force that pulls the moon toward Earth is called _Gravity_.

Explanation:

Gravity is the force that holds the planets in orbit around the sun and keeps the moon to orbit around Earth. the moon pulls the oceans towards it causing ocean tides, because of the gravitational pull. gravity creates planets and stars by pulling material together from which stars and planets are made.

Which of the following would be LEAST likely in the fossil record? Which of the following would be LEAST likely in the fossil re

GREYUIT [131]

Answer:

The correct answer is desert-dwelling species.

Explanation:

Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.

For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.

On the other hand, places like deserts would be the least likely to have a fossil record as deserts are devoid of optimum conditions required for the formation of fossils. In places like a desert, decomposition and demineralization of the components like bones take place at a brisk rate.

Gekata [30.6K]

Answer:

Prediction is correct.

Explanation:

In the body, transportation of molecules can occur in different ways or mechanism.

An example is by facilitated diffusion.

It is a passive form of transport where carrier proteins shuttle the molecule such as glucose into the cell without using energy.

Glucose being a large molecule is shuttled by glucose carriers across the cell membrane into the cell by facilitated diffusion.

Therefore an increase in the number of glucose carrier means an increase in the rate of glucose transport.

The results will show our prediction was correct.

Why are scientists interested in the origin of organic molecules? help me please...

valentina_108 [34]

Answer:

Gas from Earth's core came to the surface through volcanoes.

Recent hypotheses about the origin of organic molecules suggest that these molecules may have formed in hydrothermal vents deep in the oceans, where hot gases and elements emerge from cracks in Earth's crust.
