HELP ASAP use the particle theory to explain why hot chocolate powder dissolves more rapidly in hot water than cold water
Yuliya22 [10]

Explanation:

To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.

Which of the following lists steps of mRNA production in eukaryotes in the correct order?A) 5' cap addition, addition of poly-A
Assoli18 [71]

Answer:

The correct answer is B) Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane.

Explanation:

The transcription process in eukaryotes takes place in the nucleus of the cell and after transcription post-transcriptional modification also takes place in the nucleus which is necessary to guide the mRNA out of the nucleus.

First, the process of transcription takes place in which DNA is transcribed to mRNA by an enzyme called RNA polymerase. After transcription post-transcriptional modifications takes place in the given order.

1. Capping: In capping process 7-methylguanosine is added by capping enzyme at 5' end of mRNA.

2. Polyadenylation: In polyadenylation, many poly-A residues are added at the 3' end of the mRNA called the poly-A tail.

3. Intron splicing: Introns are the non-coding sequence present in mRNA which are spliced out of mRNA and all exons are joined together.

After these post-transcriptional process, the mature mRNA is transported out of the nucleus through the nuclear membrane.

What is digestive processes
Elina [12.6K]
<span>
The mouth is the beginning of the digestive tract. In fact,digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

The signs used depend on the species being surveyed and include the presence of runways and tracks on *
amm1812

Answer:

(a). soft substrates

Explanation:

Mobile organisms can be measured by both direct and indirect methods. Direct methods may involve observing the actual behavior (e.g., scoring via timing). Moreover, indirect methods are those where the technique used depends on the species being examined, collecting information such as through recording of tracks in the soft substrate (e.g., mud, sand, snow), presence of fur/feathers, droppings (mammals), etc. For example, indirect observation of insects may involve the determination of exoskeletons, sounds, etc.
