Answer:

A. Viruses sometimes transfer information from RNA to DNA.

Explanation:

An RNA virus is a virus that uses ribonucleic acid (RNA) as a genetic material, or that in its replication process needs RNA. For example, the Hepatitis B virus is a virus classified as a DNA virus (hepadnavirus), with the peculiarity of having its double-stranded DNA genome and the genome is transcribed into RNA during replication.Its nucleic acid is usually single stranded RNA but it can also be double stranded RNA. Single-stranded RNA viruses can, in turn, be classified according to the sense or polarity of their RNA as negative or positive. The positive RNA viruses are identical to the viral mRNA and therefore can be immediately translated by the host cell. The negative viral RNA is complementary to the mRNA and therefore must become RNA positive by an RNA polymerase before translation

Answer:

The amphipathic property of the phospholipids that constitute the membrane

Explanation:

It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.

The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.

The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.

This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.

In the first 2.5 hours after a radical neck dissection, 40 ml of medium-red, bloody fluid is obtained from the client's drainage
cluponka [151]
The nurse should assess the patient vital sign and notify the healthcare provider. For 2.5 hour after neck dissection, production of 40ml by the drainage is a bit excessive. There might be a bleeding in the site of operation that becomes the source of the drainage. Change dressing will not do anything. Applying pressure can be done if the site of bleeding is known.

DaniilM [7]

Answer:

CGTATC - DNA complementary strand- GCATG

CTTTCAAG- DNA complementary strand-GAAAGTTG

GAGACTTAC-DNA complementary strand-CTCTGAATG

Explanation:

Remember that the complementary sequence will be based on base pairing for DNA, so the A will pair with T, C with G

A class was performing an experiment to discover the pH values of some common household substances. The results of three groups
Vanyuwa [196]

The statement, which best describes the evidence that Group 3’s data are less valid than the data for the other two groups is this: GROUP 3’S pH VALUE FOR VINEGAR IS MUCH HIGHER THAN THE VALUES OF THE OTHER TWO GROUPS.

An experimental result is said to be valid, if it gives the true values of the parameters it has measure. Looking at the experimental results given in the question above, one will notice that, the pH value obtained by group 3 for vinegar is quite different from that of the other two groups. In addition, the value is wrong, this is because, vinegar is acidic in nature. The result obtained by group 3 indicates that vinegar is basic, which is wrong. This shows that the results obtained by group 3 is less valid than that of the other two groups.
