Answer:

A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

Smooth muscles depolarize as a result of a transmembrane current of Calcium ions.                                                                                                                       When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.

amid [387]

Solar power would, without doubt, be the most efficient type of power plant to build in this specific location. This is due to the fact that solar power produces no pollution in an environment. Also this type of alternative energy fits this communities resources due to the fact that the community receives primarily sun , a huge component in solar power, and little cloud coverage only increases the sun's power that much more. On the other hand, biomass needs things like wood, crops and alcohol fuels to burn in order to produce energy, some of which are not viable in this type of community because a place with little to no irrigation sources and an abundant amount of sunlight would be hard to produce any kind of natural aspect. Lastly, hydroelectric energy would not be a efficient of even viable choice because this community has no natural water available at hand to use for this alternative energy to function, and hydroelectric works primarily on a water storage.

SOVA2 [1]

Answer:

All given options are correct.

Explanation:

Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.

The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.

Thus, all the given option are correct.
