Answers

Answer:

The principles are responsible for the natural selection of organisms.

Explanation:

The principles greatly impact the  process of natural selection because these principles are responsible for the natural selection of organisms. If the organisms have all the principles of natural selection, it has more chances of survival as compared to other organisms due to the presence of the favourable characteristics. These favourable characteristics helps the organisms to increase in population because the environment is suitable for them or in other words the organisms can tolerate that environment better than other organisms. for example, polar bear survives in the polar regions because they have a thick skin full of hair that helps in the survival on the cold regions, it is an act of natural selection.

N-linked glycosylation on proteins usually translocated into the ER would not occur D. All of the above E B and C are correct

Answers

Nonsense-mediated decay (NMD) can easily interfere with the translation of the mRNA which is responsible for encoding the ER protein translocator. Therefore, option "B" is correct. The genetic code consists of three STOP codons or nonsense codons which are  UGA, UAG, and UAA.

These codons are frequently referred to as termination codons or nonsense codons. They do not encode any amino acid. Nonsense codon at the end of the polypeptide chain during translation is responsible for the end. Inserting a premature terminal codon (PTC) into a quality exon can code for incorrect mRNA, for example, cytoplasmic occasion.

Which of the following contributes the most to the total calories burned in a day?
Select one:
a. Thermic effect of food
b. Nonexercise activity thermogenesis
c. Exercise d. Resting metabolic rate

Answers

Resting metabolic rate contributes the most to the total calories burned in a day. The resting metabolic rate is the energy that is utilized by the body at rest, especially by the cells to maintain the necessary body functions. The correct answer to the given question is option d.

It is the minimum energy that the body needs to keep functioning to maintain a healthy life. It is calculated by the number of calories that the body burns when it is at rest, and when it is not digesting any food. Non-Exercise Activity

Thermogenesis: It is the energy that is expended by the body for doing non-exercise activities like cooking, fidgeting, gardening, and walking from one place to another.

Thermic Effect of Food: It is the energy that is expended by the body during the digestion, absorption, and transport of food. It takes up approximately 10% of the total calorie expenditure. It varies depending on the type of food consumed.

Exercise: It is the energy that is expended by the body during physical activity, which includes anything from running, cycling, swimming, and weightlifting. It is the only factor that can be manipulated and increased, thus, can contribute to burning the most amount of calories after the resting metabolic rate, but still is less as compared to the Resting Metabolic Rate (RMR) is a vital factor that determines the energy requirements of the body at rest. It is the energy that is expended by the body for the basic functioning of the cells and tissues, which includes breathing, heart rate, and body temperature regulation.

Resting metabolic rate contributes the most to the total calories burned in a day. The second most crucial factor is non-exercise activity thermogenesis (NEAT), which is the energy that is expended by the body for doing non-exercise activities like cooking, fidgeting, gardening, and walking from one place to another. The thermic Effect of Food is the energy that is expended by the body during the digestion, absorption, and transport of food. It takes up approximately 10% of the total calorie expenditure. It varies depending on the type of food consumed.

Which compliment pathway involves binding of compliment to the lipopolysaccharide layer of the bacterial cell wall?
a) Classic Pathway
b) Mannose-binding Lectin Pathway
c) Alternative Pathway

Answers

The complement pathway that involves binding of complement to the lipopolysaccharide layer of the bacterial cell wall is: Alternative Pathway. (Option c)

The alternative pathway is one of the three main complement activation pathways, alongside the classical pathway and the lectin pathway. It is called the alternative pathway because it can be initiated directly without the need for specific antibody-antigen complexes.

In the alternative pathway, complement proteins, such as C3, can spontaneously and continuously undergo low-level activation in the bloodstream. This activation occurs when complement proteins interact with certain molecules present on the surface of microorganisms, including the lipopolysaccharide (LPS) layer of bacterial cell walls.

The binding of complement proteins to the LPS layer triggers a cascade of enzymatic reactions, leading to the generation of complement fragments, such as C3b. These fragments can then bind to the bacterial surface, promoting opsonization (marking bacteria for phagocytosis), triggering inflammation, and ultimately leading to the destruction of the bacterial cells.

Therefore, the correct answer is c) Alternative Pathway.

How long dos it take for carbon to become a fossil fuel? how many steps are involved?

Answers

It takes more than 100 million years for carbon to become a fossil fuel. The fossil fuel formation process comprises of several steps, which include the following:

Step 1: Formation of Organic MatterThe first step in the formation of fossil fuels is the accumulation of dead organic matter. The organic matter can be animal or plant debris, such as algae, plankton, leaves, and other organisms.Step 2: Burial of Organic MatterThe second step is the burial of organic matter. As dead organic matter settles to the bottom of the ocean or a lake, it becomes buried under sediment. The sediment protects the organic matter from oxidation or decomposition by microorganisms.

Step 3: Heat and PressureThe third step involves the transformation of organic matter into fossil fuels by heat and pressure. When organic matter gets buried, the heat and pressure begin to increase. The weight of the overlying sediment causes the temperature and pressure to increase steadily. This process drives off the volatile compounds from the organic matter, leaving behind carbon-rich fossil fuels.Step 4: Formation of Fossil FuelsThe final step is the formation of fossil fuels. The transformation of organic matter into fossil fuels may take several hundred thousand to several million years, depending on the temperature, pressure, and chemical composition of the organic matter. When organic matter gets transformed into fossil fuels, it becomes coal, oil, or natural gas.

The statement is inaccurate because the product of nitrogen fixation through industrial processes does not have the same biological properties as the product of nitrogen fixation by bacteria. D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.

D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.

Explanation:

Nitrogen fixing bacteria has the responsibility in nature to trap and fix atmospheric nitrogen in ecosystems. They are very important components of the nitrogen cycle and play an important role in maintaining the balance  of nutrients in nature.

If humans discover industrial processes to fix nitrogen, the process will be unsustainable in the long run if nitrogen-fixing bacteria ever go extinct because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now across several ecosystems all over the world.

Stage 2 of short-term swim failure following immersion in cold water involves peripheral vasoconstriction, shivering, and cognitive impairment.

Explanation:

In stage 2 of short-term swim failure following immersion in cold water, several physiological changes occur. One significant change is the constriction of blood vessels in the arms and legs, known as peripheral vasoconstriction. This occurs as a result of the body's attempt to redirect blood flow to vital organs in order to maintain core body temperature.

In addition, during stage 2, shivering may begin as a way to generate heat and increase body temperature. Shivering helps the body to maintain its thermoregulation.

Finally, cognitive impairment can occur during stage 2. This includes difficulties with concentration, decision-making, and coordination, which can impact a person's ability to swim and increase the risk of drowning.
