Is a virus alive and evidence
Anit [1.1K]

Answer:

No

Explanation:

Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Tectonic plates are pieces of the ________ that float on the more fluid ________ below. A. mantle; crust B. asthenosphere; litho
Soloha48 [4]

Answer:

The answer is E.) Lithosphere, Asthenosphere.

Explanation:

Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.

From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:

i) the crust

ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)

iii) the outer core

iv) the inner core.

The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers

( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.

Andrej [43]

The answer is Proteomics.

<u>Proteomics</u> is a discipline of study that involves an examination of proteins and how the proteins encoded by genes interact to produce cell and tissue types.

What is Proteomics?

The extensive study of proteomes is known as proteomics. An organism, system, or biological setting produces a set of proteins known as a proteome. We might speak of an organ or a species' proteome (like that of Homo sapiens) (for example, the liver). The proteome is dynamic; it varies from cell to cell and alterations occur over time. The underlying transcriptome is somewhat reflected in the proteome. However, in addition to the relevant gene's expression level, a number of other factors also affect protein activity, which is frequently measured by the rate at which the processes in which the protein is engaged react.

Proteomics is employed to look into:

  • When and where do proteins expressed.
  • rates of protein synthesis, degradation, and abundance at steady state.
  • how proteins are altered, for as by phosphorylation and other post-translational modifications (PTMs).
  • the transfer of proteins among subcellular spaces.
  • protein involvement in metabolic processes.
  • what interactions proteins have with one another.
