Answer:
#1 is a reptile
Explanation:
I’m pretty sure only reptiles have scales
Proteins, nucleic acids, and carbohydrates are grouped by common structural features found within their group. lipids can be grouped based on their high solubility in nonpolar solvents, and their preponderance of nonpolar groups.
Non-polar solvents cannot dissolve a polar compounds since no opposite charge exist, and the polar compound is not attracted. It is this becuase of absence of partial charge that also makes these molecules non-polar. Some of examples of non-polar solvents include benzene, hexane, pentane, toluene, etc.
Higher the solubility of a compound is that the larger the amount of the compound which can dissolve in a solution.

Type II restriction enzymes, such as Ecor I, that make staggered cuts within its recognition sequence, are considered more effective in biotechnology because they result in cohesive or sticky ends.
<h3>What is Ecor I and why are sticky ends important?</h3>
Ecor I is a kind of restriction enzyme which is obtained from Escherichia coli. The palindromic sequence recognized by this enzyme is 5' - GAATTC - 3'. It makes the following cuts between G and A on both the strands of the DNA to form sticky ends:
5' - G↓AATTC - 3'
3' - CTTAA↑G - 5'
Sticky ends are a fragment of DNA which is produced through a staggered cut, by the use of restriction enzyme. In this the terminal portion stretches with unpaired nucleotides. These kind of ends are easy to ligate when rDNA needs to be formed.
