Fossils almost never contain DNA. So how can we know how closely or distantly related fossil organsims are to living organisms
Nostrana [21]
While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.

Answer:

all organism evolved on earth, and all are genetically related to one another. Species living under unusual conditions might defer more than others, though. We might also predict that the more similar the percentages of naturally occurring elements are in two species, the more closely related those two species are.

Why does every one have cells
jeyben [28]
<span>Everyone has cells because these are the building blocks of life. These tiny particles that clump into groups that form tissues, organs, and organ systems are what makes organisms distinct from non-living things that exist on Earth. Where there are cells, life is present, and in its absence life cannot exist as we know of today. Cells are responsible for bringing different species of organisms that are found in different ecosystems all over Earth. They are tiny but in groups they are responsible for every living organisms that have existed through time.  </span>

Carbohydrates contain carbon characterized by the atomic grouping H-C-OH and
scZoUnD [109]

Answer:

true

Explanation:

Carbohydrates, like all organic molecules, always contain carbon (C) and hydrogen (H) atoms. Carbohydrate molecules are characterized by the presence of the atomic grouping H-C-OH, in which the ratio of hydrogen atoms (H) to oxygen atoms (O) is approximately 2:1. Because this ratio is the same as the ratio in water, the name “hydrates of carbon” seems appropriate. Carbohydrates first and foremost function for quick, short-term energy storage in all organisms, including humans.
