Answer:

Viruses use their own catabolic enzymes.

Explanation:

Viruses are the infective particles present in the environment which encloses their genetic material which could be wither RNA or DNA enclosed in the protein coat.

The protein coat is made of the capsomers which are arranged in the tubular structure forming capsid. The viruses do not contain the metabolic machinery of their own that is the reason that they do not have replication or transcription or translation machinery. For this they are dependent on the host organisms as they use their machinery.

Thus, the selected option is correct.

If the mass of a material is 92 grams and the volume of the material is 25 cm3, what would the density of the material be?
olya-2409 [2.1K]
<h3><u>Answer;</u> </h3>

= 3.68 g/cm³

<h3><u>Explanation;</u></h3>

Density is given by dividing the mass of a substance by its volume.

Thus; Density = mass/ volume

In this case; mass = 92 g and Volume = 25 cm³

Therefore;

Density = 92 g/ 25 cm³

             <u>= 3.68 g/cm³</u>

Can i have help please
Hoochie [10]

Answer:

The answer is D

Explanation:

Since the structure uses light energy, we can only assume that it's a chloroplast, since only chloroplasts contain chlorophyll and can absorb light energy.

Chloroplasts use carbon dioxide and water to make glucose, with oxygen as a byproduct.

The glucose produced is then used in metabolic reactions in the organism.

Imprinting can be cell-type specific; for example, this region of chromosome 15 is ONLY imprinted in neurons and a few other spe
Ainat [17]

Answer:

The correct answer is - A and D.

Explanation:

Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.

It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.
