A false crawl<span> is when a turtle comes onto the beach with the intention of laying eggs but returns to the water without nesting. Hope this helps!

The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity. A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions. Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system supports all these functions.
7. Adenine (A), Guanine, Cytosine and Thymine are the four nitrogenous bases in DNA.
8. In DNA Cytosine always forms hydrogen bonds with guanine.
9. The sequence of nucleotides carries the genetic information of an organism.
10. The process of replication produces a new copy of an organism's genetic information which is passed on to a new cell.
11. The double-coiled shape of DNA is called a double helix
Explanation:
There are four nitrogenous bases in the DNA of an organism. Two of the bases are pyrimidines eg: Thymine and cytosine while 2 of the bases are purine bases namely adenine and guanine. The purine of one strand forms a hydrogen bond with pyrimidine of the parallel strand of DNA.
The bases are present in nucleoplasm as dNMPs and in DNA they are present as dNTPs (deoxyribonucleotide triphosphate). During replication, these dNMPS keeps on bonding with other dNMPs in the presence of ATP and as DNA Polymerase, ligase topoisomerase etc. These nucleotides form the DNA strands and they are responsible for coding proteins. The sequence of DNA is also termed as gene.
The double helix structure of DNA was given by Watson and Crick. Each strand has an alternative backbone of sugar and phosphate group. The four bases bonds with glycosidic and phosphodiester bonds with sugar and phosphoric acid.
It could be a sign of preeclampsia, which is pregnancy condition characterized by high blood pressure and signs of damage to the liver and kidneys.
<span>Edema or the swelling is usually a normal condition in pregnancy which occurs because of the excess fluid that collects in body tissues (retention of water), especially in ankles and feet.</span>
Answer: Lysine is a polymer I believe. Hope this helps.
