Answer:
3 - DNA acts as instructions for the cell
Explanation:
DNA is the Bluprint of our cells, every protein necessary for our lives is created using those instructions. every cell of every living creature contains DNA in one form or another.
Answer:
Salinity is the <em><u>salt concentration</u></em> in water. Oceans salinity and temperature affect density of water, Higher the salinity denser the water and Lower the temperature denser the water.
Explanation:
As we go down in the ocean , temperature goes down and denser the water.
Less dense water will be on top and higher the density will be on bottom. Warmer water will be on top.
Salinity <em> increased</em> in ocean on evaporation of sea water and formation of ice in water. Weathering of rocks , formation of soil also add minerals and salt in ocean.
Melting of snow, ice in sea, addition of river freshwater and precipitation of rain <em>decrease </em>the salinity of ocean.
The main difference is that organisms that have similar characteristics could be in the same species or have common ancestors
Answer:
Anticodon Definition. Anticodons are sequences of nucleotides that are complementary to codons. They are found in tRNAs, and allow the tRNAs to bring the correct amino acid in line with an mRNA during protein production. Their anticodons, which pair-bond with codons on mRNA, allow them to perform this function.

Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
