the chromatin condenses
into visible chromosomes
Answers
Answer: DNA and proteins contained in the nucleus, known as chromatin, condenses. ... The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. ... The spindle starts to form during prophase of mitosis

Why is water called the universal solvent?

B.) Water can act as a solvent in many different solutions
C.) Water is a polar substance that dissolves nonpolar substances
D.) Water can act as a solute in many different solutions
Answers
Answer:
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.
Explanation:
B.) Water can act as a solvent in many different solutions.
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees.Therefore, option B. is correct.

How did the mutation change the hemoglobin protein?
ASAP
Answers
Answer: A mutation Changes by its mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
Explanation:
A mutation changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.

The order of Replication include the following:
DNA helicase unwinds DNA.Replication fork is formed.DNA polymerase attaches to primer.DNA polymerase adds nucleotides (5' to 3').Okazaki fragments bound by ligase.DNA replication involves the production of two copies of DNA from one

strands after which a replication fork is formed from the two single strands.

nucleotides to the leading strand of DNA in the 5' to 3' direction. Okazaki
