Viruses are organisms that share traits with both living and non-living organisms. The virus' genetic material is made up of both DNA and RNA.

Viruses have an exterior capsule layer and a specified boundary. Only the host cells provide energy to the virus. They thrive and mature, multiplying their numbers solely within the host cells.

A virus is a single-celled with no more than one cell. In the virus, there is no internal organization. If a virus is present outside of the host environment, it does not grow, develop, or require energy. Viruses do not remove trash.

Answer:

0.315 hectares

Explanation:

To get the answer, we use the area of a trapezium formula, which is ½ (a+b) h, where a and b are the parallel sides and h is the height.

So ½(90m+50m) 45m

½ × 140 × 45

70 × 45 = 3150m²

10000m²= 1hectare

3150m² = x

3150 ÷ 10000 = 0.315 hectares.

The quark composition of a deuterium nucleus is 3 up quarks and 3 down quarks.

Quarks are the most fundamental particles that make up the atomic nucleus. All solid matter that we know is made of three particles, which are the up and down quarks, 'u' and 'd', and the electron.

In this case we have that the composition of the quark in the nucleus will be 3 up quarks and 3 down quarks.

A protein which has many sulfhydryl (-sh) groups may exhibit disulfide bridges tertiary structure.

A disulfide bond is a covalent bond between two atoms of two (cysteine ​​side chains). Large polypeptide chains (more than 200 amino acids) fold and form domains.

Some proteins have disulfide bridges, which are inter-chain interconnections or between parts of a chain, formed by the oxidation of cysteine ​​radicals. Intracellular proteins generally lack disulfide bonds, while extracellular proteins often do.

The evidence for evolution

In this article, we'll examine the evidence for evolution on both macro and micro scales.

First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events.

At the end of the article, we'll finish by seeing how microevolution can be directly observed, as in the emergence of pesticide-resistant insects.

The nuclear envelope distinct the process of transcription and translation in the cell. It controls the release of mRNA from the nucleus through the biological process of transcription. Thus, the correct option is B.

A nuclear envelope may be characterized as a positively regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells.

The process of transcription occurs inside the nucleus and transforms DNA into mRNA, while the process of translation occurs in the cytoplasm which transforms mRNA into specific proteins.

Explanation:

The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.

This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.

This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.

The difference in an area with high concentration and an area with low concentration is called concentration gradient.

Concentration gradient refers to the difference between the concentrations of two solutes in a solution.

A solution usually contains an area or region with higher concentration and an area with lower concentration.

Unicellular organism are one celled but multicellular organisms are made up of many cells.

As the name suggests, unicellular organisms are made up of only one cell and this single cell carries out all the essential functions that are needed for the survival of the organism like respiration, photosynthesis etc.

But in multicellular organization, the organisms are made of more than one cells and cells are grouped according to their functions. Each group is specialized for specific functions. Even in higher multicellular organisms the group of cells form specific types of tissues and further they form organs and organ systems which function more efficiently.
