Answer:
Explanation:Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability
Answer:
Sequence of nucleotides in the DNA strand
Explanation:
Deoxyribonuceic acid or DNA is a biological material that stores the genetic information of an organism.
DNA encodes the information through the order or sequence of the nuceotides along each strand. Organisms differ from one another because their respective DNA molecule have different nucleotide sequences and consequently, carry different biological instructions.
A DNA strand consists of two polynucleotide chains, composed of four nucleotide subunits. Each of these chains is known as DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together. DNA nucleotides are composed of a 5-carbon sugar (Deoxyribose) to which are attached one phosphate group and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). The nucleotides are covalently linked together.
So base on the question that states and ask to give the name of one cell type that continues to divide throughout a person's lifetime and also on who does not, with that question, the cell that divide through persons lifetime is a Mitosis or skin cells, an example to this is the skin, and the who doesn't divide is i think the brain cells, it doesn't regenerate
Its defensive, warning coloration is bright colors. Such as poisonous dart frogs, they are brightly colored in order to warn predators they are poisonous
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).
