Chromosomes control cell processes. they do this
a. destroying foreign organisms that invade the cell.
b. providing energy for the cell to use.
c. coding for the production of all a cell’s proteins
d. providing a site for the synthesis of the cells proteins

Answer:

Chromosomes control cell processes by coding for the production of all a cell's proteins.

Explanation:

Chromosomes are the complex structures that are made up of DNA and attached histone proteins that stabilize the nucleosome structure. DNA is made up of a sequence of polynucleotides that encodes the genetic information of that organism.

The combination of three nucleotides known as triplet codon provides a unique code for a particular amino acid. After transcription of the DNA sequence into mRNA, it is sent to the cytoplasm of the cell to be translated into a particular protein. There are many proteins in a cell each having different sequence and hence they differ in their folding which give them a particular structure to perform a particular activity. Hence different DNA sequences encode the information for different sequences of amino acid in a polypeptide chain which makes the protein.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
