Answer:
Explanation:
1) homologous features:
these are the features or structures that have a similar structure in several different organisms but function in a unique way in all of them. these structures indicate anatomical similarities as well as the same ancestry of different organisms. for example, the forelimb of birds, humans, dogs, and whales, perform different functions in all these organisms. but when we analyze the layout of bones or layout of the arrangement, we find that it is very similar across all of them. this indicates that, the ancestor of all these organisms was, but with the passage of time when organism dispersed, and environmental conditions changed, it was evolved into different organisms as per favorable conditions.
2) molecular biology:
as we know that all living organisms are a compilation of billions and trillions of unique biological molecules, that group in a unique fashion to constitute the whole organism. interestingly, some biological molecules and the process of their formation can provide sound evidences of evolution. for example, DNA, a sequence of nucleotides in DNA, amino acids, the process of transcription, translation, etc.
the study of evolution through molecular uniformity has led to the foundation of a novel branch of evolution called phylogenetics. the sequence of nucleotides in DNA is used to find the best possible ancestor of any organism. for example, phylogenetic analysis has found that the origin of eukaryotes is from prokaryotes over the period of time.
3) fossil records:
fossils are the preserved remains of previously living organisms or their traces, dating from the distant past. this doesn't mean that fossils represent the complete skeleton of an organism because many organisms don't even fossilize and those who fossilize don't have complete remains. nonetheless, the fossils that humans have collected offer unique insights into evolution over long timescales. for example, the study of horse fossils has enabled the scientists to reconstruct a large, branching "family tree" for horses and their now-extinct relatives.
D. Mass consumption
is the answer
Imagining the illustration where a<span> pencil is beside a metric ruler, </span>scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number and o<span>ne end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6, we can conclude that the precise and accurate measurement of the ruler would 5.5 centimeters. Since the point is pointing in the midway of 5 and 6, we can interpret that the point is pointing in the exact half between 5 and 6 thus we can conclude that this would be a 0.5 addition to 5, giving us the 5.5 cm.</span>
The answer is; rock A
The thermal difference and intermittent showers are the reason the rock fractures and peels. The below freezing temperatures cause the rainwater in the cracks of the rock to freeze. When water freezes, it expands causing stress in the rock. The large temperature range causes thawing and freezing of the water and this alternation causes the rock to crack in the end.
Since rocks are not good conductors of heat, the outside of the rock heats up and cools faster than the inside of the rock. This causes stress that causes the rock to peel.
