Answer:
The double helix is a description of the molecular shape of a double-stranded DNA molecule. ... Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.
Answer:
Explanation:
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together. Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.
2. What do you call the structure of the DNA?
DNA is made up of molecules called nucleotides. ... Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs

Why do cells need to replicate their DNA?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.
Laroi
Answer:
Cells need to reduplicate their DNA because this ensures that each cell gets a copy of the genome ( inheritance of genetic traits ). DNA replication is an essential process and the basic mechanism in all organisms.

if a cell does not go through the s phase of the cell cycle before mitosis what might be wrong with the daughter??
Answer:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

How one variable affects another happens in:
A. surveys.
B. case studies.
C. observations.
D. experiments.
The one variable affects another happens in experiments. Thus, option D is correct.
What is experiment?An experiment, or experimental research, is a research method in which the researcher manipulates or changes the value of one variable, (the independent variable) and measures the variable that is considered the dependent variable, in order to find how the change affects it.
The other three posible answers, observational research, survey and case study are also research methods, but the researcher can't manipulate or control any of the variables, these methods are used only to measure a specific variable.
Therefore, The one variable affects another happens in experiments. Thus, option D is correct.

Listed in blue, please help!! Is biology and chemistry two different things and why?
Answer:
Yes they are two different things!
Explanation:
Chemistry is more basic to existence-it is the study of the composition of matter and all associated structures, properties, and reactions. This includes, but is not limited to, biological matter. Biology meanwhile is focused entirely on biological organisms.
Answer: Yes they are
Explanation: Biology is the study of life and the ecosystems of what surrounds it. Biology consists of anatomy marine biology and the spheres of the earth. Chemistry has to do with our elements take gold for example it is known as Au or Aurum. Element 79 with an atomic mass of 196.96657u you will learn this in chemistry. Chemistry makes biology like a scratch on the surface because in chemistry you are going deep into the elements by classifications and the periodic table. You will be able to learn about dissolvents and why salt dissolves in water. You will learn about molecules in both fields. In general, biology is more the basis of life and chemistry is the more complexity of life.

A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
There is no mother cell after a paramecium divides because it is divided by binary fission and the paramecium is divided into two identical cells, called daughter cells, there is no mother cell left.
What is paramecium?Paramecium is a protist. It is oval-shaped with cilia all over the body, and it is minute and can be seen only under a microscope. It engulfs its food through the body cavity, which is its mouth.
Binary fission means when the cell is divided into two daughter cells. The division is asexual reproduction. The cell divided DNA into two copies and then each cell gets the DNA.
Thus, there is no mother cell after a paramecium divides since binary fission is used and the paramecium is split into two identical cells, known as daughter cells.
