Answer: Genetic code (genes and genome) and the mechanisms of replication.RNA determines a cell’s function, synthesizing proteins and enzymes. Mutations, changes in DNA instructions, are the molecular basis of evolution. Nucleic Acids are the basis for the storage and transmissions of hereditary information in all cells.
Explanation:
RNA serves as the hereditary information for viruses that lack DNA. Although, typically single-stranded in most cells, in viruses they can be either single-stranded or double-stranded. Double-stranded RNA is an indicator or a viral infection.

Hemophilia is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree.In the pedigree that is shown, which represents Irene's allele combination?
Answer:
XHXH
Explanation:
Hemophilia is an inherited genetic disorder that affects the body's ability to manufacture blood clots, which is a necessary step to prevent bleeding. Hemophilia A and B are both X-linked recessive illnesses, although females are not affected. X-linked recessive inheritance is a kind of inheritance in which a mutation in an X-chromosome gene causes the phenotype to be manifested in males who are hemizygous for the gene mutation because they have one X and one Y chromosome.

3-4µm
4-5µm
2-5µm
Answer:
option 1
Explanation:
The size of most prokaryotic cells is about in diameter.
1-2µm
The size of most prokaryotic cells is about 1-2µm in diameter. Therefore option A is correct.
Most prokaryotic cells are relatively small, typically ranging in diameter from 1 to 2 micrometers (µm). Prokaryotes are unicellular organisms without a true nucleus or membrane-bound organelles.
Their small size is advantageous as it allows for efficient nutrient uptake and waste elimination, facilitating rapid growth and replication.
Despite their small size, prokaryotic cells are highly diverse and can be found in various environments, including soil, water, and even within the human body.
Therefore option A is correct.

Which best describes the nature of cellular respiration?
OIt is an energy-seeking process.
OIt is an energy-gathering process.
OIt is an energy-releasing process.
OIt is an energy-destroying process.
The nature of cellular respiration is an energy-releasing process. Therefore, the correct statement is option C.
What is the process of cellular respiration?The process of cellular respiration releases energy. In order to liberate energy from foods and create ATP (adenosine triphosphate), the molecule that transports energy in cells, a metabolic process takes place in the cells of living things.
Organic substances, like glucose, are broken down in a sequence of enzyme processes that release the stored energy, which is then collected in the form of ATP, during cellular respiration.
Since this process takes place in the presence of oxygen, it is also known as aerobic respiration. Living organisms depend on cellular respiration to survive because it helps in the transportation of the energy needed for all of their cellular functions.
Therefore, the cellular respiration is an energy-releasing, and a metabolic process takes place in the cells of living things.

A normal breath takes in about 1.0 L of air. If air has an average molar mass of 28.8 g per 1 mol and has a density of 0.97 g/mL, how many molecules of air do you take in with each breath
Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.
What is densityDensity is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
What is Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of molecules of airIn this case, you know that:
Density= 0.97 [tex]\frac{g}{mL}[/tex]Volume= 1 L= 1000 mLReplacing in the definition of density:
[tex]0.97 \frac{g}{mL}=\frac{mass}{1000 mL}[/tex]
Solving:
mass= 0.97 [tex]\frac{g}{mL}[/tex] ×1000 mL
mass= 970 g
Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.
Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?
amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole
amount of molecules= 2.0286×10²⁵ molecules
Finally, you take 2.0286×10²⁵ molecules of air.
