At the heart of the sun, the temperature and pressure is enough to drive ___________ reactions. These reactions release energy from the surface of the sun by emitting light or releasing high energy particles.
A) fission
B) fraction
C) frisson
D) fusion

Answers

At the heart of the sun, the temperature and pressure are enough to drive fusion reactions. Therefore, the correct option is D.

The process of the fusion reaction is powered by the sun when two or more light nuclei merge or converge in order to form a single heavier nucleus. This process liberates energy from the surface of the sun.

The energy is liberated as a result of the formation of a single nucleus with the help of two or more light nuclei. This energy is less than the mass of the two original nuclei. The temperature and pressure both play critical roles in this methodology.

During anaerobic cellular respiration in skeletal muscles, pyruvic acid produced by _____ is converted into _____.

Answers

Answer:

During anaerobic cellular respiration in skeletal muscles, pyruvic acid produced by glycolysis is converted into lactic acid.

The glycolysis is the process by which one molecule of glucose is converted into two molecules of pyruvate.

During anaerobic respiration in muscles (such as occurred during exercise) the lactic acid fermentation takes place by which the pyruvate is converted into the lactic acid. The reaction is catalyzed by the enzyme lactic acid dehydrogenase.

Pyruvic acid is produced as a result of the breakdown of glucose through glycolysis. This pyruvic acid is utilized during anaerobic respiration to form lactic acid in the muscles.

Further Explanation:

The cellular respiration involves both aerobic and anaerobic respiration. Both the respirations starts from glycolysis with the formation of pyruvate. The pyruvate either enters the aerobic pathway or anaerobic pathway depending on the condition of the cell.

During aerobic respiration, the cell produces 36 ATP with oxygen as the final acceptor of electrons. It is a process involving multiple steps and includes glycolysis as the initiator process. The pyruvate thus formed is converted into acetyl CoA which then enters the Krebs cycle. In the Krebs cycle, series of reactions occur with the production of ATP, FADH2, and NADH. The electrons from FADH2 and NADH are transported to the electron carriers in the electron transport chain which in turn results in the formation of ATP with the liberation of oxygen.

During anaerobic respiration, glycolysis still occurs as it is oxygen-independent process. Due to the absence of oxygen, the resulting pyruvate cannot enter the Krebs cycle and therefore, undergo the aerobic pathway. The pyruvate breaks down anaerobically to form lactic acid which is a common phenomenon in the muscles during exercise. At the time of exercise, glycogen is the main source of energy which eventually is cleaved to form glucose which finally produces pyruvic acid through glycolysis. The pyruvic acid generally enters the oxidative phase of glycolysis in order to produce ATP but due to the absence of oxygen during excessive exercise the pyruvate enters anaerobic phase. In this phase, lactic acid is produced from pyruvate which is released into the bloodstream. The muscles undergo anaerobic respiration because the energy demand by the cells overpowers the oxygen supply to the cell which is necessary for the production of ATP.

A material with a higher R-value is a better insulator

A material with a higher R-value is a better insulator.

The R-value is a measure of a material’s (such as a layer of insulation) resistance to conductive heat flow. Materials with higher R-value indicate better insulating properties or effectiveness. Certain factors such as the thickness, density and the type of insulation determine the R-value of most materials while for some insulation, it is also determined by aging, temperature and moisture accumulation.

Do you think that there is a difference between the male bodybuilding and the female bodybuilding communities?

Answers

Yes, due to the different body types.
Final answer:

Yes, there is a difference between the male and female bodybuilding communities, primarily attributing to biological differences, social and cultural aspects, and varying intensity or duration of workouts. Despite these differences, both communities share the universal goal of building and sculpting muscle to improve overall fitness.

Explanation:

Yes, there is a difference between the male and female bodybuilding communities primarily because of the biological differences between males and females. This difference can be attributed to various factors such as hormonal differences, muscle mass, and fat distribution. Regardless of the physical disparities, both sexes can build their individual strength and physique fitting to their goals.

Furthermore, the social and cultural aspects play a significant role in shaping these communities. Society often imposes different expectations and standards on men and women, even in something as specific as bodybuilding. Historically, the male bodybuilding community has been more prominent, however, the female bodybuilding community has been steadily growing and gaining recognition.

The intensity and duration of specific workouts may also vary to accommodate the unique physiological responses of each sex. However, it’s important to note that the primary goal of bodybuilding - to build and sculpt muscle, enhance strength and improve overall fitness - remains the same for both genders.

Gravel is____than clay.
A. Less permeable
B. less porous
C. more permeable

Answers

Gravel is more permeable than clay.

Answer:

Option C, More Permeable

Explanation:

Gravels are more permeable than the clay. This is so because the gravel particles are large in size and therefore the inter particle space in gravel is large which allows more water (or any other fluid) to flow through it while in case of clay, the particles are very fine and minute due to which the inter particle space between the clay particles is very very small which allows reduced flow volume through the clay particle as compared to the gravel particles.
