The salt concentration in a cell's cytoplasm is 0.9%. The cell is placed in a 10% salt solution. Which term best describes the 1
fenix001 [56]

The term that best describes the 10% salt solution relative to the cytoplasm of the cell is ' Hypertonic'

Explanation:

When the concentration of two solutionare compared they can be described as hypertonic, hypotonic or isotonic with relation to one another.

When two solutions have same concentration and osmotic pressure they are said to be isotonic solutions.

The solution which has higher molecular concentration and higher osmotic pressure than the other solution is called hypertonic solution.

The solution which has lower molecular concentration and lower osmotic pressure with respect to other solution is called hypotonic solution.

Here the solution of salt has a higher concentration than cell sap so it is a hypertonic.

Are genes a segment of DNA containing a set of instructions for making a protein ?
brilliants [131]

Answer: The given statement is True.

Gene can be described as the segment of DNA ( deoxyribonucleic acid), which codes for a particular protein. The protein thus formed, corresponds to a specific trait ( such as skin color, hair color, color of eye) of the individual organism.

They possess set of  instructions for making a protein in the form of nucleotide sequences. Gene undergo transcription to form mRNA ( messenger RNA), which is then converted into particular protein through translation.

Genes are inherited from parents by their offspring and in this way specific traits are inherited by offspring from their parents.

Thus, given statement in the question is correct.
