Answer:

Evidence for evolution comes from many different areas of biology:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).

An air pressure of 1,005 millibars is equivalent to approximately how many inches of Mercury?
N76 [4]

1005milibars of pressure corresponds to 29.68inches of mercury.

Option D.

<h3><u>Explanation:</u></h3>

Mercury has a density of around 13.6gm/cc. Thus the pressure of inches of mercury will have a huge effect on the value. As far as bar is concerned, it's around the normal atmospheric pressure measured at sea level. Its around 1,00,000 pascals. So from converting a pressure at millibars to inches of mercury, we need to divide the value by a factor of 33.864.

So, pressure in milibars =1005milibars.

So, pressure in inches of mercury = 1005/33.864 = 29.68 inches of mercury.

How can these forelimbs explain how life changes over time?
dmitriy555 [2]
It is the last choice because their similar bone structures suggest they once had a common ancestor, which is why they are all mammals.

which classification level is broader than the kingdom level; which branch of biology is concerned with the naming and classifyi
shtirl [24]

Domain is broader than the kingdom level.

Levels of classification that are broader than phylum are regions and kingdoms. There are five kingdoms: Monrea, Protista, Fungi, Plants.

Taxanomy is the branch of biology concerned with the naming and classifying of organisms.

Protists are described as diverse organisms because they have many different characteristics. They are either heterotrophs or autotrophs. They are also eukaryotes that are not classified as plants, animals or fungi.

Animals group of organisms includes only multicellular heterotrophs.

If two species belong to the same class, they also belong to the same taxon higher up in the hierarchy. Here they belong to the same side and kingdom.

The gradual change in a species over time is called Evolution.

The levels of classification that are broader than the phylum are domains and kingdoms.

Taxonomy is the science of naming, describing and classifying all living organisms, including plants.
