Answer:

Change in food source.

Explanation:

If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.

Natural selection can contribute to variations in gene frequency throughout time as a result of changes in food supply.

If the organism's food supply changes, it will have to adjust to the new situation.

For example, Darwin's Theory on the Galapagos Islands' finches. There were several distinct types, ranging in size and beak shape. This happened due to changes in food supplies, and they evolved in order to access more of them.

The correct order of this energy transfer process is as follows:

Thus, the correct option is A, i.e. 3, 2, 1, 5, 4.

The Cellular processes may be defined as those processes that occur in living organisms in order to regulate the communication between cell requirements and body utilization.

The initial step in the cellular process is that the energy is utilized by the mitochondria in order to construct ATP. Then, the energy is significantly absorbed by cells from the sunlight that later converts into chemical form as a product known as glucose.

Energy is further released when glucose is broken down into pyruvate and ATP is broken down to ADP.

Therefore, the correct order of energy transfer from the sun to the molecules that power the cellular processes of organisms is well described above.

Explanation:

They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.

The Miller-Urey experiment tested the hypothesis that life, or more precisely organic molecules, might have arisen by nothing more than straightforward chemical processes by simulating the conditions on the early Earth.

Miller's result confirmed A.I. Oparin's theoretical hypotheses, and it is regarded as the standard experiment looking into the hypothesis of abiogenesis.

The Miller-Urey experiment was the first attempt to investigate theories regarding the beginning of life experimentally. Stanley Miller recreated circumstances that were supposedly typical on the early Earth.

Therefore, They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.

Answer:

C

Explanation:

Answer:

One way in which the functioning of plant cells is similar to the functioning of animal cells is that they are both eukaryotic cells. This means that they both have membrane organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Moreover, these similarities in cellular structure help each cell function in a similar manner.

Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

This method  of natural selectionthat the fantastic alleles of this variation organism are surpassed directly to offspring, the system of  natural selection results in evolution occurring.

Natural selection is the system thru which populations of residing organisms adapt and extrade. Individuals in a populace are evidently variable, which means that they're all one of a kind in a few ways.

The answer is A. process information from stimuli and respond.

Good luck :)

The main function of the central nervous system is to process information from stimuli and respond. So, the correct option is A.

The brain and spinal cord are two examples of the vast network of nerve tissues that make up the central nervous system (CNS). It controls and regulates various biological processes including movement, sensation, perception and cognition. It is in charge of processing and coordinating sensory input and muscular output.

The CNS collects information from the body's sensory organs, interprets and integrates it, and then generates the necessary responses to support the body in maintaining homeostasis and responding to its surroundings. The CNS is also involved in higher-order processes that include reasoning, picking up new information, and memory. The primary job of the central nervous system is to process information from stimuli and act.

Therefore, the correct option is A.

Answer:

variation in a population exists

Explanation:

Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.
