Which explanation correctly describes why it is important for a cell's surface-area-to-volume ratio to not be too small? Radio button Not checked 1 of 4
Answer:
Hello. You did not put the options, but we can say that the execution of mitosis is what makes it important that the proportion between the colume and the cell surface area is not small.
Explanation:
The ratio between the surface area of a cell and the volume is very large and this is essential for mitosis to occur and for all cells in the same tissue to have the same content and the same drum.
If a cell increases ten times its surface area, it will increase its volume a thousand times. This shows that the cell volume has a much larger proportion than the surface. This makes the cell have a fast metabolic rate and needs to absorb many nutrients, in addition to making a strong exchange of gases with the external environment. This absorption of nutrients so intense, is essential for the cell to enter mitosis and generate two equal cells. This is because during the growth phase the cell will increase in volume until the growth limit of its surface area, once this limit is reached, the cell will have to undergo mitosis and will have enough nutrients for the entire process.

what is the function of DNA and RNA
Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.
Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.
Answer:
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.
Explanation:
RNA:
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.
DNA:
The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

Which of the following is essential to proper functioning of all prokaryotic and eukaryotic organisms?
A.) O2
B.) CO2
C.) ATP
D.)NaCI
Answer:
I think its B. CO2
Explanation:
Oxygen is only needed for eukaryotes so not A
ATP is the product of prokaryotes
And I highly doubt its salt
ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.
For example, biochemical reactions in mitochondria switch power from fatty acids and pyruvate molecules into a power-wealthy molecule referred to as adenosine triphosphate (ATP). Subsequently, the relaxation of the organelles uses this ATP because of the supply of the power they want to operate.
Each organelle helps one-of-a-kind sports inside. Mitochondria, for example, are organelles that offer eukaryotes a maximum in their power with the aid of using generating power-wealthy molecules referred to as ATP. Prokaryotes lack mitochondria and rather produce their ATP on their floor membrane
What is enzyme synthesis?The feature of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) withinside the F1 sector. This is viable because of power derived from a gradient of protons which move the internal mitochondrial membrane from the intermembrane area into the matrix via the Fo part of the enzyme.
Hence concluded that ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

Science rejects any hypothesis not supported by __________________________ and the results of ___________________________ experiments. what are the blanks?
Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

what are several defenses that keep pathogens from getting inside the body
Answer:
The body has two lines of natural defense to protect against infection. The first are physical barriers, such as the skin, body secretions and mucous membranes. The second line of defense is the immune system. Specialized immune cells coordinate and execute attacks to kill germs that make it past the body's physical barriers.
