Answer:

D. Stomach

Explanation:

One of the most important digestive enzymes that aids digestion by breaking down of ingested food, most especially proteins is pepsin, which is usually referred to as "stomach enzyme".

Pepsin is found secreted in the stomach.

The pH of the stomach is usually low, between 1.5 to 2 (acidic). This acidic environment of the stomach actually favors this stomach enzyme, as it activated the pepsin to perform it's function.

Based on the observations made by the students, it can be concluded that pepsin aids digestion most in the stomach. It's pH requirement to function optimally matches with the pH of the environment of the stomach.

Answer:

Metabolic pathways can be broadly divided into two categories based on their effects. Photosynthesis, which builds sugars out of smaller molecules, is a "building up," or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a "breaking down," or catabolic, pathway.

Explanation:

The best describe action of glycogen phosphorylase is :- This enzyme catalyzes a phosphorolysis reaction.

Glycogen phosphorylase is an enzyme that breaks down glycogen, which is a stored form of glucose in animals and humans. It catalyzes the phosphorolysis of glycogen, meaning it cleaves the glycogen molecule by breaking the glycosidic bond between glucose units using inorganic phosphate (Pi) as a nucleophile. This results in the release of glucose-1-phosphate (G1P) as the product.

"This enzyme adds a glucose unit to glycogen" is incorrect. Glycogen phosphorylase breaks down glycogen by removing glucose units, not adding them.

"This enzyme exists predominantly in the same form in muscle and liver" is incorrect. There are two different isoforms of glycogen phosphorylase, known as muscle isoform (GP-MM) and liver isoform (GP-LL), which have different properties and are found in different tissues.

"This is the only enzyme needed for the complete degradation of glycogen" is incorrect. Glycogen degradation requires multiple enzymes, including glycogen phosphorylase, glycogen debranching enzyme, and phosphoglucomutase, among others, to completely break down glycogen into glucose for energy production.

Ultraviolet light can be the answer to future outbreaks because it has the capability to kill the microorganisms present in air and thus can prevent the infectious diseases caused by them.

Ultraviolet light is the EM radiation with the wavelength range 10 nm to 400 nm. It is already being used in research labs for maintaining the microbe free environment. Researches are also being conducted to produce such ceiling lights that can be used normally in households so that the the air-borne microorganisms can be killed.

Microorganisms are the small living organisms not visible to the unaided eyes. They have the strong capability to produce their new variants by mutation and cause infectious diseases. The ultraviolet light can kill them even before they are able to transform themselves.

Explanation:

Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.

When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.

These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.

This change in alleles frequency is what we call adaptation.

Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.

In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.  

So, in the exposed example, we are focussing on rabbits populations.  

• The selective pressure or modeling environmental factor is predation by the introduced hawk.

• The rabbits´ response to predation is the survival of only those that carry mutations ⇒ tan or brown fur

• Natural selection benefits these mutations.  

• Tan or brown rabbits survive and increase their fitness.

The statements used as evidence to support the argument that "DNA influences the proteins that are made":

The 1st statement shows that different alleles of the same gene can lead to the production of different proteins. The 2nd statement shows that the presence of two HbS alleles leads to the production of a protein that causes sickle cell anemia.

These statements provide evidence that the DNA sequence can affect the structure and function of proteins. In the case of sickle cell anemia, the presence of two HbS alleles results in the production of abnormal hemoglobin, which causes the red blood cells to form a sickle shape. This can lead to a variety of health problems, including anemia, pain, and stroke.

Given a bacteria culture starts with 2000 bacteria. a) It take 2.93 hours for the number of bacteria to double ; b) It will take  4.21 hours. for the bacteria population to grow to 90000.

a) After 6 hours the estimated count is 60 000. Round your answer to 2 decimal places of an hour. For calculating the time taken for a number of bacteria to double, we use the formula, t = (ln 2)/k where, t = time, k = doubling time (in hours), and ln = natural logarithm. Given that the initial number of bacteria is 2000 and the number of bacteria after 6 hours is 60 000. The estimated growth rate, k = (ln N₁  - ln N₀ )/(t₁  - t₀ ) where N₁ is the final number of bacteria, N₀ is the initial number of bacteria, t₁ is the final time, and t₀  is the initial time. So, we have k = (ln 60 000 - ln 2000)/(6 - 0) = 1.418 / 6 hours = 0.236. Therefore, t = (ln 2)/k = (ln 2)/0.236 = 2.93 hours (approximately) to double the number of bacteria. Hence, the answer is 2.93 hours.

b) Assume the doubling period was half an hour.  Round your answer to 2 decimal places of an hour. Given that the doubling period was half an hour. Therefore, the growth rate, k = 1/doubling time = 1/0.5 = 2 per hour. Let t be the number of hours to grow to 90,000 bacteria. Then, we have 90,000/2000 = 2^(t/0.5) => 45 = 2^(t/0.5) => ln 45 = (t/0.5) ln 2 => t = (ln 45)/(0.5 ln 2) = 4.21 hours (approximately). Therefore, the answer is 4.21 hours.

Since, unlike oil, source like wind, solar, water etc. come naturally we don't and can't replace them but when the viscosity in oil has been used up it must be change to allow the proper functioning of the machine.

The next resource that is a nonrenewable resource is the oil that is present in the third option, as the oil is a fossil fuel that is formed over millions of years and is not renewable on human timescales.

Nonrenewable resources are natural resources that are finite and cannot be replenished or regenerated on a human timescale, and they are formed over millions of years, and their supply is limited, as oil is a nonrenewable resource that is formed from the remains of plants and animals that lived millions of years ago. These were buried under layers of sediment and rock, and over time, heat and pressure caused them to decompose and transform into oil, and the problem with nonrenewable resources like oil is that they are finite, meaning that there is only a limited supply of them.

Hence, the next resource that is a nonrenewable resource is the oil that is present in the third option.

The rabbit population increased during years when the death rate was lower than the birth rate, reflecting a higher carrying capacity.

The carrying capacity of an environment is described as the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available.

Population is known to refer to the number of people in a single area, whether it be a city or town, region, country, continent, or the world.

The primary and I think the most obvious cause of population growth is an imbalance between births and deaths.

The reason is to prevent desaturation during the endoscopic procedure.

For endoscopic procedures, moderate sedation is used. Hypoxia is a common complication seen during endoscopy, especially in the elderly. Artificial ventilation must be used during endoscopic procedures so that minute ventilation is not reduced.

Airway, respiration and oxygenation are monitored closely during endoscopy to prevent hypoxia. Hypoxia is a condition characterised by decreased levels of oxygen in the body. But rapid adsorption of oxygen causes lung collapse. This condition is known as atelectasis. It may cause pneumonia and infection. The best way to prevent this complication is pre-oxygenation with 80% oxygen.
