4. If two objects have the same mass but different volumes, the one with the larger

kenny6666 [7]

Answer:

Explanation:

Let's start with the formula for density.

Density = mass / volume

The mass is a constant. So it has no effect on the answer. Call it 10 grams in both cases.

The volume of the small object is 10 cc.

The volume of the larger object is 30 cc

Density of the small object = 10 grams / 10 cc = 1 gram / cc

Density of the larger object = 10 grams / 30cc = 1/3 gram / cc

Conclusion.

If the mass is held constant, the higher the volume, the less the density.

Every so often Brainly publishes a fun fact. The fact is "Saturn would float in a bathtub filled willed with water." The bigger the volume, the smaller the density.

The dicer enzyme processes dsRNA and forms siRNAs, which suppress the expression of target genes by cutting mRNA. 1) siRNA 2) RNA.

<h3>What are siRNA fragments?</h3>

siRNA means small interfering RNA. This is a silencing RNA molecule involved in the RNA interference mechanism, intervening in the expression of a specific gene.

siRNAs are complementary double-stranded RNA molecules composed of about 20-21 nucleotides. siRNA originates from a long double-stranded RNA (dsRNA).

The dicer enzyme cuts dsRNA molecules and produces siRNA. siRNAs suppress the expression of target genes when cutting messenger RNA.

siRNAs suppress the expression of target genes by cutting the complementary messenger RNA (mRNA) into two halves. This is accomplished by the interaction of the siRNA with the RISC complex (RNA-induced silencing complex).

The two mRNA halves are later degraded by the cellular machinery, leading to the suppression of the gene expression.

siRNAs also participate in other pathways related to RNAi, such as in antiviral defense or in the chromatin structure organization.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme dicer cuts dsRNA into smaller fragments called (1) siRNA, which form a complex with RISC and degrade specific (2) RNA.
