Answer:

D. Nucleic acids attach to the bases in the DNA.

Explanation:

Transcription begins when an enzyme called RNA  polymerase  is added to the DNA template and begins a new chain a new chain to produce complementary RNA.

During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.

RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.

Therefore, D. Nucleic acids attach to the bases in the DNA.

Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. the p
Olenka [21]

Answer is hypertonic.

The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.

How many covalent bonds can carbon make?
Ostrovityanka [42]

Answer:

4

Explanation:

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
