Answer:
Steps of Respiration
1. Oxygen is inhaled into the body and diffuses across the alveoli in the lungs, where it is taken up by red blood cells. Oxygen is a vital raw material for cellular respiration, as it is required for the production of energy in the form of ATP.
2. Glucose, a simple sugar, is broken down through a series of chemical reactions known as glycolysis, producing ATP and other by-products such as pyruvate and NADH. If oxygen is present, pyruvate is further broken down through a process called the citric acid cycle (also known as the Krebs cycle), producing even more ATP and NADH. If oxygen is not present, the breakdown of pyruvate through fermentation occurs instead.
3. Carbon dioxide is produced as a by-product of cellular respiration. It is a waste product of the breakdown of glucose and other organic molecules, and it is exhaled out of the body through the process of respiration. Fermentation is a type of anaerobic respiration that occurs in the absence of oxygen. It produces ATP through the breakdown of pyruvate, but at a lower yield compared to aerobic respiration. Fermentation also produces other by-products such as ethanol or lactic acid, depending on the type of fermentation taking place.
The RNA World hypothesis explains that ribonucleic acid (RNA) is the missing link between simple organic molecules and complex organic molecules. Explain the two roles that RNA played in connecting the two types of molecules
The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules. DNA, RNA, and proteins are central to life on Earth.
RNA was thought of as little more than a messenger between DNA and proteins, carrying instructions as messenger RNA (mRNA) to build proteins. However, RNA can do far more. It can drive chemical reactions, like proteins, and carries genetic information, like DNA. And because RNA can do both of these jobs, most scientists think life as we know it began in an RNA world, without DNA and proteins.

Which set of conditions would most likely cause a change in gene frequency in a population that reproduces sexually
Small population size is most likely to result in changes in allele frequencies in a population. So, the correct option is (B).
The relative frequency of an allele (gene variant) at a specific locus in a population, expressed as a fraction or percentage, is known as allele frequency or gene frequency. It is the proportion of all chromosomes in the population that carry that allele divided by the entire population or sample size. Microevolution is the change in allele frequencies that happens within a population over time.
Given the given facts:
A specific location on a chromosome and a specific allele at that siteA population of N people with ploidy n, which means that each person has n copies of each chromosome in their somatic cells (e.g. two chromosomes in the cells of diploid species)In the population, the allele is found on I chromosomes.Learn more about gene frequency to visit this link

What happens when protease is added to protein?
When protease is added, proteins breakes into smaller polypeptides or single amino acids, and forms new protein products.
A protease is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids and promoting the creation of new protein products. It is also known as a peptidase, proteinase, or proteolytic enzyme.
They achieve this by using hydrolysis, a mechanism in which water breaks bonds, to cleave the peptide bonds found in proteins. Protein digestion after ingestion, protein catabolism (the breakdown of aged proteins),[3][4] and cell signaling are only a few of the biological processes that proteases are involved in.
All living forms and viruses have proteases. They have repeatedly developed independently.

What is the passing of genes from parents to children called?
The passing of genes from parents to children is called heredity.
Inheritance, also called heredity or biological inheritance, is the passing of traits from parents to offspring. Through either asexual or sexual reproduction, progeny cells or organisms acquire the parent's genetic information. Heredity refers to the genetic heritage inherited from our biological parents. More precisely, it is the transference of traits from one generation to the consequent. These traits can be physical, such as eye color, blood type, disease, or behavioral.
In humans, eye color is an example of a genetic trait or Heredity.

The DNA of a cell is not programmed to coordinate the activities needed to keep a large cell alive. How does cell division help the cell avoid DNA overload
The process of cell division helps the cell to avoid DNA overload by the following mechanism: Each daughter cell has its own copy of DNA and can coordinate all the activities of a smaller cell.
Thus, the correct option for this question is B.
Cell division may be defined as a process through which a parent cell significantly divides into two daughter cells with an identical amount of genetic material.
DNA overload deals with the mechanism of the larger the cell, the greater the requirement for the positioning of the cell's DNA. In order to prevent this mechanism, a cell undergoes the process of division that limits the phenomena of DNA overloading.
This happens with the help of synthesizing two new daughter cells that limit the size of the parental cell. Therefore, the correct option for this question is B.

How do you find the effort force of a second class lever?
In a class two lever the force of the effort multiplied by the distance of the effort from the fulcrum is opposite and equal to the force of the resistance multiplied by the distance of the resistance from the fulcrum.
The force utilized to move an object across a distance is called an effort force. To use a rudimentary machine to perform work on an item, this force must be overcome. By dividing the load by the number of ropes, we may get the pulley's effort force. F is the effort force in the diagram.
For instance, when using a shovel, you hold one end stable to serve as the fulcrum and pull up on a load of soil with your other hand. The resistance force is the dirt being picked up, and the effort force is the second hand.

The Venn diagram compares aerobic and anaerobic respiration. Uses of pyruvic acid could be categorized in the overlapping section of the Venn diagram.
In order to produce energy in the form of ATP molecules, aerobic respiration involves the complete breakdown of a glucose molecule in the presence of oxygen (36 molecules of ATP).
Contrarily, anaerobic respiration entails the partial breakdown of a glucose molecule to produce energy in the form of ATP molecules without the presence of oxygen (2 molecules of ATP).
The use of pyruvate is a characteristic shared by both aerobic and anaerobic respiration (pyruvic acid). The glycolytic process, which is the same for both processes, produces pyruvic acid.
