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

What is the process of water moving through the soil called answers?

Furkat [3]

The process of water moving through the soil is called percolation or ground water recharge. In this process water oozes, seeps, or filter through the soil beneath the surface, without a defined channels, or in a course that is unknown and not discoverable from surface indications without excavation for that purpose. Percolation and infiltration are two related but different processes describing the movement of water through the soil. Infiltration involves the downward entry of water into the soil or rock surface while percolation is the flow of water through soil and porous or fractured rock.<span />

A fish has a head 9 inches long. the tail is equal to the size of the head plus one half the size of the body. the body is the s

Katena32 [7]

So let’s substitute that into the third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now we know the value of B and the value of H. Substitute this back into the second equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4: Plug all values of H, T, and B into the final equation. Total length of fish = H + T + B Total length of fish = 9 +27 + 36 = 72.

GalinKa [24]

Answer:

LPL Lipoprotein Lipase

Explanation:

LPL is a ubiquitous enzyme that is found in the lumen of blood capillaries. It hydrolyzes the tracilglycerols of lipoproteins rich in triacylglycerols and breaks them down to free fatty acids and glycerol, releasing them into muscle and adipose tissue. It also allows the uptake of the resulting free fatty acids by the underlying tissues.
