Why are DNA and rna important for cells

Answers

Answer 1

Answer:

Answer:

They constitute the genetic material of living beings and act in the formation of proteins.

Explanation:

Both DNA and RNA are extremely important for life: they constitute the genetic material of all living beings. In the case of eukaryotic organisms, nucleic acids are present in the nuclei of cells, while in prokaryotic organisms (which have no nucleus surrounded by a membrane), the genetic material is dispersed in the cytoplasm. In addition, DNA and RNA are extremely important for the formation of proteins that will command all the functions of our body.

Sodas typically contain sugar, flavorings, coloring agents, and carbon dioxide dissolved in water. The best term to describe this mixture would be _____. A) an aqueous solvent
B) an aqueous solution
C) a solution
D) a solvent
E) a solute

Answers

Answer: The correct answer is aqueous solution

Explanation:

The mixture is best described as AQUEOUS SOLUTION because water is the solvent used to dissolve the various solutes (sugar, flavorings, coloring agents, and carbon dioxide). The resulting mixture is a aqueous solution known as Soda.

Animals conduct certain behaviors in mating. Some practice _____, in which one male breeds with only one female, and others practice _____, in which one male breeds with multiple females.

Answers

The answer is monogamy and polygyny.

Both terms have a Greek origin. By knowing their origin, it is easy to understand the terms.
Monogamy literally means one marriage, from the Greek monos - one, alone, and gamos - marriage. So, in monogamy, one male breeds with only one female.
Polygyny literally means many wives, from the Greek poly - many, and gyny - wife, woman. So, in polygyny, one male breeds with multiple females.

Which of the following is true of vertebrates with four-chambered hearts?There is a partial gas exchange in one chamber of the heart.

There is no mixing of oxygen-rich and oxygen-poor blood.

There is a complete mixing of oxygen-rich and oxygen-poor blood.

Answers

Answer:

There is no mixing of oxygen-rich and oxygen-poor blood.

- -

The right atrium and right ventricle of the human heart pump oxygen-poor blood to the lungs and the left atrium receives oxygen-rich blood. They never mix.

A critical feature of the plasma membrane is that it is selectively permeable. this allows the plasma membrane to regulate transport across cellular boundaries--a function essential to any cell's existence. how does phospholipid structure prevent certain molecules from crossing the plasma membrane freely?

Answers

The structure of the plasma membrane makes it selectively permeable, enabling it to regulate the transport substance into and out of the cell, such as
- small, non polar molecules are hydrophobic
- Polar molecules and ions are hydrophilic
- Polar molecules and ion usually pass with the help of protein

hope this helps

The factor which makes the permeability of the plasma membrane a main reason for the cells existence is that this condition makes the cell a to take in important required substances and throw out waste. Thus, the life of the cell is based the fact that the plasma membrane is selectively permeable.

Further Explanation:

Eukaryotic cells are the cells which have membrane-bound organelles, membrane-bound nucleus, and several chromosomes. They have a true nucleus and have some similarity with prokaryotic cells like plasma membrane, cytoplasm, and ribosomes.

Plasma membrane is selectively permeable as they allow only certain molecule to pass through them. This permeability is dependent on many factors one of them being the need of the molecule by the cell. The membrane of the cell is made up of following components;

1. Phospholipid bilayer

2. Transmembrane proteins

3. Interior protein network

4. Cell surface markers

Out of these components the one responsible for maintaining the movement of the chemicals or molecules across the membrane is the phospholipid bilayer and the transmembrane proteins. The major component which acts as an permeability barrier is the phospholipid bilayer.

Cellular respiration is best associated with the: A.) Golgi apparatus. B.) ribosome. C.) mitochondrion. D.) chloroplast. E.) microtubule.

Answers

Answer:

Explanation:

Cellular respiration is best associated with the organelle mitochondrion.

Final answer:

Cellular respiration is associated with the mitochondria, where cells generate energy by breaking down glucose and other food molecules

Explanation:

Cellular respiration is best associated with the mitochondrion (option C). This is an important cellular process that enables cells to generate energy by breaking down glucose and other food molecules in the presence of oxygen. The mitochondria in our cells carry out this process, converting the chemical energy in food to a form the cell can use. While the Golgi apparatus, ribosome, chloroplast, and microtubule have crucial roles within the cell, they are not directly related to or responsible for cellular respiration.
