The correct answer is microbiology.  
<span>
Microbiology is the branch of science that study microorganism. It contains a few sub-disciplines including virology (study viruses), parasitology (study parasites), mycology (study fungi) and bacteriology (study bacteria). Studied microorganism might be unicellular (one cell), multicellular (cell colony), or acellular (without cells).</span>

In addition to naming species, Linnaeus also grouped species into a hierarchy of increasingly inclusive categories. The largest
Semmy [17]

Answer:

The correct answer is D) domain

Explanation:

The father of taxonomy is Linnaeus. Taxonomy helps in classify and naming organisms. The modern taxonomy has eight levels of classification. Domain, kingdom, phylum, class, order, family, genus, species.

Domain is the highest level of classification so it is the largest category that would include closely related species. When we go from domain towards species the number of similarities increase and number of organism decrease and vice versa is true when we move from species to domain. So the right answer is domain.

Explanation:

When humans mass produce items for others to buy, those factories that make that stuff release carbon dioxide into the atmosphere which kills the ozone layer (the ozone layer basically protects everything on this planet from the suns dangerous UV rays). On the other hand humans try to help out the environment for example those cars that people use that use electricity and not fossil fuels as energy for the car and the fossil fuels have the same affect as the factories but the electricity does not release the fumes that the fossil fuel cars do. Hope this answers your question!

WARRIOR [948]

Keratinocytes are differentiated skin cells found in the outermost layer of the epidermis. Dendritic cells are antigen-presenting cells that play important roles in the adaptive immune response.

  • In addition to keratinocytes, the <em>stratum spinosum</em> also contains another epidermal cell type called epidermal DENDRITIC cells that help to fight infection.

  • The s<em>tratum spinosum</em><em> </em>is an epidermal skin layer between the <em>stratum granulosum </em>and<em> stratum basale</em>.

  • Dendritic cells are antigen-presenting cells that are capable of processing harmful antigens in order to present them on the cell surface to the T cells of the immune system.

"DNA denatures at a higher temperature than does protein, yet its structure depends on relatively weak hydrogen bonds. Why the d
Reika [66]

The option are not given and the options are:

Proteins are denatured by breaking covalent bonds.

Linear molecules like DNA are inherently stable.  

Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.

Answer:

The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

Explanation:

Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.

DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
