True. ATP (adenosine triphosphate) and PCr (phosphocreatine) are energy sources used for high-intensity, short-duration exercises such as weightlifting, sprinting, and jumping.

Both ATP and PCr are stored in small amounts within the muscles and are readily available for immediate use during intense physical activity. During exercise, ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, releasing energy that is used for muscle contractions. When ATP levels decrease, PCr is rapidly broken down to provide additional energy for the resynthesis of ATP. However, these energy systems can only sustain high-intensity exercise for a limited time before becoming depleted. After that point, other energy sources such as glucose and fat metabolism must be used to fuel continued exercise.

Genetic modification is the method of modifying an organism's genetic structure by using recombinant DNA (rDNA) technology. A gene from another animal is most commonly applied to the genome of an organism to give it a phenotype that is desired.

Immigration into the gene pool would NOT be a source of increased genetic variation in a population.

Immigration is the process of movement of individuals from one geographical area to another. In biology, it is a form of population dispersal, where individuals may travel across regions in order to find more suitable living conditions, such as food and shelter.

Immigration can also be a way to repopulate an area where there is a decrease in the population due to death or emigration. Immigration is a natural process that helps to create genetic variation and adaptation in populations and can be beneficial for the species population.

Therefore, Immigration into the gene pool would NOT be a source of increased genetic variation in a population.

Answer:

Natural selection

Explanation:

Microevolution refers to changes produced at a lower level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these naturally produced changes by mutation, natural selection, genetic flux, genetic drift.

After the drought on Daphne Major, many of the plants producing small-sized seeds decreased their reproductive rate drastically. Consequently, there were almost no seeds available for the medium ground finch to feed. The population of this species also decreased to only a hundred birds over two years. Weather conditions and food availability influenced the survival of the animals.

With time, the finched population increased again, but now, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.

Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to crack open the husks and eat the contents of the seeds.

Natural selection was responsible for the rapid change in the finches´ population beaks size after the drought. The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.  

The protein that, when mutated, would inhibit backward but not outward transport along axon microtubules is called dynein.

Dynein is a motor protein that moves along microtubules and is responsible for retrograde transport, meaning it moves toward the cell body. When dynein is mutated, it can cause disruptions in retrograde transport, but not in anterograde transport, which moves away from the cell body. Specifically, mutations in dynein can result in a phenotype known as "retrograde transport defects," which can lead to the accumulation of vesicles and organelles in axons and dendrites. This can lead to various neurological disorders such as Huntington's disease, which is characterized by dynein dysfunction.

The phosphorylation of glucose during glycolysis refers to the process in which a phosphate group is added to a glucose molecule, producing glucose-6-phosphate.

This step is critical in glycolysis because it traps the glucose molecule in the cell and provides the necessary energy to drive subsequent reactions. Specifically, the addition of the phosphate group to glucose requires the hydrolysis of an ATP molecule to ADP and Pi, releasing energy that drives the reaction forward.

The glucose-6-phosphate molecule can then be further processed through the glycolytic pathway to produce ATP and other important metabolic intermediates. Therefore, the phosphorylation of glucose during glycolysis is a key regulatory step in cellular energy metabolism.

When a vesicle moves along microtubules toward the center of the cell, the molecular motor(s) kinesins are used. Kinesins are one of the two primary molecular motor families that are responsible for the movement of vesicles. The process of movement of vesicles is called axoplasmic transport.

Kinesins move cargo towards the plus end of microtubules while dyneins move cargo towards the minus end. These motor proteins take advantage of the polarity of microtubules by moving towards the end with beta-tubulin exposed at the surface of the microtubule. The movement of kinesins along microtubules is powered by ATP hydrolysis, which provides energy for the movement.

Kinesin moves along microtubules by undergoing conformational changes that cause the motor to "step" forward in a hand-over-hand manner. Kinesins have a head and tail domain, with the head domain containing the microtubule-binding domain and the ATP-binding site. The tail domain of kinesin binds to vesicles and other cargo and transports them along the microtubule, similar to how legs move along a conveyor belt.

Antagonistic pleiotropy is a genetic phenomenon where a single gene affects multiple traits, with positive effects on some traits and negative effects on others. In the case of aging, it is possible that the set of genes responsible for causing aging in humans also have positive effects on other aspects of health and fitness, such as reproductive success and immunity.

If we were to alter these genes in some way to extend lifespan, it is possible that we would inadvertently disrupt the positive effects of these genes on other traits. For example, if a gene that promotes cellular repair also increases the risk of cancer, altering it to extend lifespan could also increase the risk of cancer. Similarly, if a gene that enhances immunity also increases inflammation and tissue damage, altering it to extend lifespan could also compromise the immune system and increase susceptibility to infections.

Thus, the concern with altering the set of genes responsible for causing aging is that we may be trading off lifespan for other aspects of health and fitness. This is not to say that we should not pursue research on extending lifespan, but rather that we should be mindful of the potential trade-offs and strive to understand the full scope of the genetic and physiological mechanisms involved in aging before attempting to manipulate them.
