Answer:
C 30-40
Explanation:
The overall net gain of ATP in cellular respiration per one molecule of glucose is - between 30-40 (aerobic respiration)
In aerobic respiration, macromolecules such as glucose break in the presence of oxygen to produce energy. That occurs in mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle, and ETS.
Glycolysis is the first stage of cellular respiration that is a metabolic pathway of glucose that takes place in the cytosol. Here, the glucose molecule converts into two molecules of pyruvic acid or pyruvate that forms ATP and NADH as energy.
In glycolysis - six ATP molecules are produced.The citric acid cycle is the second stage where In the citric acid cycle, two molecules of ATP are produced.Oxidative phosphorylation of cellular respiration that produces FADH₂ two and eight NADH molecules that produce ATP.=> Two ATP molecules = one molecule of FADH₂ and, therefore, the number of ATP produced from 2 FADH₂ - 4 ATP.
=> NADH = ATP molecules by each molecule and therefore the number of ATP produced from 8 NADH - 24 ATP.
=> The number of ATP produced from the one glucose molecule under aerobic respiration is given as follows:
From glycolysis = 6 ATP
From citric acid cycle = 2 ATP
From FADH₂ = 4 ATP
From NADH = 24 ATP
total 36 ATPs.
Thus, under aerobic respiration 36 molecules of ATP are produced from one molecule of glucose thus, the correct answer would be - between 30 - 40.

DNA technology is especially useful in detecting and treating human diseases that are genetic in nature.
What is DNA technology?
DNA technology is a set of techniques used to study and manipulate DNA, the genetic material found in all living organisms. DNA technology has enabled the detection and treatment of human diseases that are genetic in nature.
How is DNA technology useful in detecting human diseases?
Genetic diseases can be caused by changes in DNA sequences or mutations in a single gene. DNA technology can detect these mutations through genetic testing and gene sequencing.
For instance, diseases like cystic fibrosis and sickle cell anemia can be detected using DNA technology.
How is DNA technology useful in treating human diseases?
DNA technology can also be used to treat genetic diseases. One way this is done is through gene therapy. Gene therapy is a process of replacing, modifying, or supplementing the non-functioning gene with a functional one.
By using gene therapy, the root cause of the genetic disease is addressed rather than just treating the symptoms.
Summary, DNA technology is especially useful in detecting and treating human diseases that are genetic in nature. DNA technology is used to detect mutations in genes that cause genetic diseases. Gene therapy is a technique used to treat genetic diseases by replacing, modifying, or supplementing non-functioning genes with functional ones.

Chemically-defined generation of human hemogenic endothelium and definitive hematopoietic progenitor cells
The generation of human hemogenic endothelium and definitive hematopoietic progenitor cells from pluripotent stem cells has been a topic of scientific research in the field of developmental biology.
Hemogenic endothelium refers to a specialized type of endothelial cells that have the capacity to transition into hematopoietic stem and progenitor cells, which are the precursors for all blood cell lineages. Definitive hematopoietic progenitor cells are the cells that have acquired the ability to generate mature blood cells. The chemically-defined generation of human hemogenic endothelium and definitive hematopoietic progenitor cells involves mimicking the developmental cues and signaling pathways that occur during embryonic development.
These chemically-defined approaches provide valuable tools for studying the development of blood cells and have potential applications in regenerative medicine, disease modeling, and drug discovery. However, it's important to note that despite the progress made, generating fully functional and engraftable hematopoietic stem cells from pluripotent stem cells remains a challenge, and further research is needed to optimize these protocols and improve their efficiency.

Red blood cells can be separated from blood plasma using a centrifuge. This device spins the whole blood samples rapidly in a circular path and can generate forces many times that of gravity. The more dense material (red blood cells) accumulates at the outer end of the container while the less dense material (plasma) is closer to the centre of rotation. One " g " is the equivalent of 9.80 ms^−2
. How many "g"s is experienced by the material spinning in the centrifuge at a distance of 19.5 cm from the centre of rotation at 2,360 revolutions per minute? Calculate your answer in mks units correct to three significant figures.
To calculate the acceleration in "g"s experienced by the material spinning in the centrifuge, we need to convert the distance from the center of rotation from centimeters to meters.
Convert the revolutions per minute to radians per second, and then apply the formula for centripetal acceleration.
1 meter = 100 centimeters1 revolution = 2π radiansFirst, let's convert the distance from centimeters to meters:\(19.5 cm = 19.5/100 m = 0.195 m\)Next, let's convert the revolutions per minute to radians per second:
2,360 revolutions per minute \(= 2,360 * 2\pi /60\) radians per second ≈ 247.38 radians per second
Now, we can calculate the acceleration in "g"s using the formula for centripetal acceleration:acceleration = (angular velocity)^2 * radiusangular velocity = 247.38 radians per secondradius = 0.195 macceleration \(= (247.38)^2 * 0.195 = 119,078.4 m/s^2\)Finally, let's convert the acceleration to "g"s by dividing it by the acceleration due to gravity: acceleration in "g"s \(= 119,078.4 m/s^2 / 9.80 m/s^2 =12,143.76 g\)
Therefore, the material spinning at a distance of 19.5 cm from the center of rotation in the centrifuge experiences approximately 12,143.76 "g"s.

Answer:

Explanation:
list and describe three factors that affect how quickly enzymes can work to catalyze reactions
Answer:
The correct answer is - temperature, pH, substrate concentration.
Explanation:
Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.
Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.
pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.
Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

In the given data, (a) fish families and (b) fruit fly species show **variation in offspring size**. This variation can be attributed to different factors, including reproductive strategies and environmental influences.
The size of offspring in both fish families and fruit fly species can be influenced by various factors, such as genetic traits, reproductive strategies (e.g., number of eggs laid, parental care), and environmental conditions (e.g., food availability, temperature). These factors can result in different patterns of offspring size within and between species. For example, some fish may produce numerous small eggs, while others may invest more resources into fewer, larger eggs. Similarly, fruit fly species may exhibit different egg sizes or larval growth rates, reflecting adaptations to their specific ecological niches. By evaluating the data, researchers can gain insight into the evolutionary processes and ecological factors shaping offspring size in these diverse groups of organisms.
