Answer:

Outcome variable (dependent variable)

Explanation:

In a scientific investigation, a DEPENDENT VARIABLE (also known as outcome variable) is the variable that is being measured. The dependent variable, as the name implies, responds to the changes made to the independent variable.

For example, in an experiment where the effects of different concentration of fertilizer is used to test plant growth (height), the HEIGHT OF THE PLANTS is the dependent variable because it is the variable being measured.

alekssr [168]

Answer:

Genetic code

Explanation:

Genetic code refers to the set of rules by which the information encoded in the genetic material is translated into the proteins. The genetic code is present on the genes in the form of triplets of nucleotides  called codons which specifies the specific amino acid.

The codon system of the genetic code rules allows the 4 different nucleotides to form specific amino acids by the combination of the four different nucleotide in the triplets.

Thus, Genetic code is the correct answer.

They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. </span>
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.<span> </span>
