Answer:

Modern birds are descended from a group of two-legged dinosaurs. Based on these life-giving characteristics, scientists have concluded that theropods were ancestral birds. Perhaps the bird evolved from dinosaurs by accepting animal's pattern.

Explanation:

The respected scientific consensus is that the birds are Teherod dinosaur groups that continued living during the Mesozoic era. The velociraptor has a skull simmilar as the coyote and the brain of an pigeon.

Of course, these are just theories. It is not proven that birds evolved from dinosaurs, but many characteristics are leading to this theory, especially after the discovery of the primitive bird Archeopterik in Germany.

Which of the following is an
Vera_Pavlovna [14]
It’s either A or B. I would probably say A because, In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter using the oxidation of inorganic compounds or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse. Groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria. Many microorganisms in dark regions of the oceans use chemosynthesis to produce biomass from single carbon molecules. Two categories can be distinguished. In the rare sites where hydrogen molecules are available, the energy available from the reaction between CO₂ and H₂ can be large enough to drive the production of biomass.

Physical limits on the flow of ______________into and _________of the cell prevent most cells from being too large.
Nonamiya [84]

Answer:

materials/out

Explanation:

Physical limits on the flow of <u>materials</u> into and <u>out</u> of the cell prevent most cells from being too large.

<em>The limitation of the kind and amount of materials that flow into and out of the cell prevents the cell from being too large. The function of selectively allowing materials to enter and leave the cell is carried out by the cell membrane. While being permissible to some materials, it shuts some materials off and, thus, the size of the cell is maintained. </em>
