A.mutagens
B.RNA
C.chromosomes
D.proteins
Answer:
Proteins
Explanation:
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

The diagram below shows a portion of the rock cycle.
At what location in the diagram is granite most likely formed?
Location A
Location B
Location C
Location D
Answer:
location b is the answer
At location B in the diagram, the granite is likely to be formed. so, the correct option is (B).
What is Granite?
Granite is a coarse-grained intrusive igneous rock which is composed of quartz, alkali feldspar and plagioclase. It is formed from magma with a high content of silica and alkali metal oxides which cools slowly and solidifies underground.
It is a light-colored plutonic rock found throughout the continental crust, mainly in mountainous regions consisting of coarse grains of quartz, potassium feldspar and sodium feldspar. All these minerals make up more than 80% of the rock.
Granite is used in counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments.
Thus, at location B in the diagram, the granite is likely to be formed. so, the correct option is (B).

Hello(: I need some help what is an
(Allele)
Answer:
An allele is a variant of a gene. Everyone has at least 2 alleles for every gene. Because of this, humans are known as diploid organisms.
Explanation:
Genes are the complex proteins that give us hereditary traits such as hair and eye color. But genes mutate, with at least 2 copies per single gene. These copies are known as alleles.
What does each individual letter on the side of a punnet square represent?
A. DNA form parents
B. Heterozygous parents
C.Different alleles form parents
D. Same genes from parents
Answer:
The word "heterozygous" simply means that your biological mother and your biological father, when they contributed their copies of a particular gene to you, they did so in a way so that the DNA sequence is slightly different. It can be different at one point in the gene, or it can be different at dozens and dozens of different points in the gene. i know it is B because the web showed me something that told me b but it would not let me submit that

Molecule X contains chains of amino acids. What is molecule X?
Answer:
Protein, polypeptide chain
Explanation:
If you are just starting to learn biology then the answer is probably proteins!
The molecule X contains a chain of amino acids. The molecule X is called the polypeptide chain. It is formed by the process of translation in the cell.
How is the polypeptide chain formed?The chromosome contains the gene. The gene transcribes to form the mRNA. The mRNA is taken as the base for the translation process.
In the translation process, the codons present on the mRNA are read by the tRNA. A codon consists of three consecutive nucleotides. A tRNA carries an amino acid at the 3' end and reads the mRNA from 5' - 3'. AUG stands for methionine, for example.
After reading the frame, tRNA adds the amino acids. The amino acids are joined with each other by peptide bonds and form a polypeptide chain. Polypeptides contain different types of amino acids, such as aromatic amino acids, hydrophobic amino acids, etc. The polypeptide synthesis takes place on the ribosome with the help of translation proteins, ATP, GTP, etc.
Hence, the molecule X is a polypeptide chain.

Give an example of chemical energy in the body turning into thermal energy.
A. a reptile absorbing heat from the sun and turning it into heat in the body
B. using stored energy in the form of lipids to provide motion such as running
C. using stored energy in the form of lipids to provide heat energy such as shivering
D. a warm blooded animal creating heat energy from the body moving during working
out
Answer:
energy?
Chemical energy of a chemical substance can be transformed to other forms of energy by specific chemical reactions. For example, when a fuel is burned, the chemical energy is converted to heat energy. When digested food is metabolized within in a biological organism, chemical energy is also converted into heat energy.
