<h2>Answer:</h2>

The rate of dissolving decreases in <u>B. Insulated container</u>.

<h2>Explanation:</h2>

Solubility refers to the process at which a solvent gets completely dissolved in solution. It is a type of factor which paves way for speeding up of the mixing process. The factors such as stirring, temperature, surface area, polarity, molecular size, etc., has great influence upon the dissolving rate.  

When we stir a solution, it increases the dissolving rate of solute in solvent. Likewise when the temperature is increased, it also paves way for faster rate of dissolution. The surface area also acts as major factor for rate of dissolving because; when more area is available it leads to faster dissolving.  

Among the options given below, insulated container does not increase the rate of dissolving.

If the concentration of salt in the fluid surrounding cells decreases and the concentration of other solutes remains constant?
svetoff [14.1K]

Answer:

The cell will swell.

Explanation:

The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.  

This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.

Mutations in DNA include deletions and insertions. These types of mutations:
pantera1 [17]

Answer:

(A). Result in different amino acids to be read due to frame shifts

Explanation:

Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.  

These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.

This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.

Thus, the correct answer is option (A).

After his stroke, brain slowly recovered function in his right arm. the property of the brain that supports learning and recover
dusya [7]

The correct answer is neuroplasticity.

Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.
