Skeletal muscle has E. mitochondria and a rich blood supply.

Muscles are an active means of movement. Muscle contraction begins when the central nervous system, namely the muscles and spinal cord, issues impulses or action potentials to motor neurons. Acetylcholine releases calcium ions and forms actin and myosin cross bridges.

Myosin will bind to actin and pull it in which requires a lot of ATP. This binding releases ADP as well as phosphate and then the myosin head binds to new ATP, causing it to release actin. Withdrawal of actin by myosin is what makes muscle fibers shorten and contract according to the impulses given. Because of this, skeletal muscles have many mitochondria and a rich blood supply because muscle contractions require a lot of energy.

The frequency of the heterozygotes will be 2pq for as long as HWE is maintained in the population, with respect to this gene. (option 2)

This is a prediction that follows from the conditions/assumptions of the Hardy-Weinberg Equilibrium model. In other words, the frequency of heterozygotes (Aa) in a population can be calculated using the equation 2pq, where p and q are the frequencies of the two alleles (A and a) in the population.

This assumes that the population is in HWE, meaning that there is no evolution occurring due to factors such as mutation, gene flow, natural selection, or genetic drift. The HWE model provides a baseline for understanding how allele and genotype frequencies are expected to behave in a population over time.

Wavelike contractions of the muscle fibers in the stomach and intestinal walls are called peristalsis.

Peristalsis is a coordinated muscular movement that propels contents through the digestive tract. It involves rhythmic contractions and relaxations of the circular and longitudinal muscles in the walls of the stomach and intestines. These contractions create wave-like motions that push food, liquid, and other materials along the digestive tract in a forward direction.

The main function of peristalsis is to facilitate the mixing and propulsion of food, allowing for digestion and absorption to occur efficiently. It is an involuntary process controlled by the enteric nervous system, which is the network of nerves within the gastrointestinal tract.

Long-toothed rabbits have an advantage when consuming food. When long teeth seem to be prevalent, this mutation, unlike the others, will spread throughout the population.

Rabbits without long teeth have a higher mortality rate and are unable to pass on their genetic traits to their progeny. By selecting for either long or short teeth, natural selection aids in this adaptation. Rabbits with long teeth would be able to eat well, but those with short teeth wouldn't be able to break branches. The development of this trait is aided by a mutation or hereditary variation, and those who survive will indeed pass on long teeth attribute to their progeny.

The movement of air in and out of the lungs occurs by the process of Ventilation.  

What is pulmonary ventilation?

Pulmonary ventilation is basically breathing. It is the movement of air in (inhalation) and out (exhalation) the lungs. Pressure differences between the gases inside the lungs and the atmosphere is the reason air flows.

Recoil of elastic tissues and muscular breathing movements create the changes in pressure which results in ventilation.

Inhalation:  or also called inspiration, is when air is taken into the lungs. Since it is a result of muscle contraction, it is an active phase of ventilation. The diaphragm contracts during inspiration, and the thoracic cavity increase in volume.

Exhalation: or also called expiration, is when air is let out of the lungs during breathing. The diaphragm relaxes during expiration and the elastic tissue recoils, which decreases the thoracic volume.

Therefore, the movement of air in and out of the lungs occurs by the process of Ventilation.

→ Interphase, Mitosis, Cytokinesis ←

Interphase - stage where the cell prepares for Mitosis. During this stage the cell grows and replicates DNA.

Mitosis - part where the chromosomes are separated and are separated into 2 nuclei.

Cytokinesis - part where cells officially splits into two daughter cells.

Cell cycles are events that involve various series of steps for the cell to grow. It follows the order of interphase, mitosis, and cytokinesis. Thus, option D is correct.

The cell cycle is an important part of the growth and cell division of the eukaryotic cell. It includes interphase comprising the G₁, S (synthesis/replication), and G₂ phase, mitotic phase, followed by cytokinesis and G₀ phase.

The cell spends the majority of its time in interphase where the genetic material undergoes preparations and gets duplicated for the further process. In mitotic division the actual division of the organelles and the nucleic acid takes place.

Mitosis is followed by cytokinesis where the cytoplasm of the cell gets separated to form two daughter cells after the telophase stage. The cell then undergoes the G₀ phase which is the quiescent stage of the cell division where no cell division occurs.

Therefore, option D. interphase, mitosis, and cytokinesis are the correct order of the cell cycle.

In ecology, density is a measure that refers to how many individuals a population has in a specific habitat.

Considering this, we can say that water is a density-dependent limiting factor, since this is a limited resource that can vary its availability annually, but also is a species have too many individuals, all of them will not have the same capacity to reach this resource, especially when we talk about large animals or plants.

Diseases caused by bacteria would be also a density-dependent limiting factor, since only when too many microorganisms of a pathogenic species replicate in our bodies, do we begin to feel the symptoms of that illness.

Predators are also a density-dependent limiting factor since the species which they feed on can be overhunted by them, being reduced in number of individuals, or being not too much hunted and increase their individuals.

Earthquakes are a density-independent limiting factor, since they do not depend on other factors to occur, but only on the movement of our planet's plates.

Finally, limits population regardless of how many organisms are present in the area is a density-independent limiting factor, since they do not depend on how many organisms they're to limit the increase of the population. Being this option an abiotic kind of non-limiting factor.

The matter within the system is recycled when organisms die. That is option C.

The law of conservation of energy which is applicable in any type of habitat states that energy is neither created nor destroyed but is transferred from one form to another.

The biotic part of the environment are those living organisms found in an ecosystem. Examples are the human being, plants, animals, fungi, and bacteria.

The abiotic part of the environment are the non living part of the ecosystem that helps in the shaping of the environment.

When the living organism die, they are broken down by decomposers and the nutrients are recycled into the soil to be taken up again by plants, but most of the energy is changed to heat during this process.

The relationship between sickled hemoglobin (HbS) allele frequency and malaria endemicity in Africa can be best explained by the statement: When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.

Sickle cell disease is a genetic disorder caused by a mutation in the gene that codes for hemoglobin. The HbS allele is responsible for the production of abnormal hemoglobin, leading to the characteristic sickling of red blood cells. However, individuals who carry one copy of the HbS allele exhibit increased resistance to malaria, a mosquito-borne infectious disease prevalent in Africa.

The map showing the allele frequency of HbS and malaria endemicity in Africa reveals an interesting pattern. In areas where malaria is holoendemic (high prevalence), the HbS allele frequency ranges from 0.52 to 4.04. This indicates that a moderate presence of the HbS allele is associated with a higher prevalence of malaria. It suggests that individuals carrying one copy of the HbS allele have a survival advantage in regions with intense malaria transmission.

Conversely, in areas that are malaria-free, the HbS allele frequency is relatively low, ranging from 0 to 4.04. This suggests that the HbS allele is not favored in regions without the selective pressure of malaria. In malaria-free areas, individuals without the HbS allele do not experience the detrimental effects associated with sickle cell disease, and therefore, the allele frequency remains low.

In summary, the statement "When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04" best explains the relationship between HbS allele frequency and malaria endemicity in Africa. This suggests that the presence of the HbS allele is positively correlated with the prevalence of malaria, indicating a selective advantage against the disease in holoendemic areas.

The homologous traits of related species can be explained by the Theory of Evolution. This theory states that species evolve over time from a common ancestor.

As species diverged from each other, they adapted to the new environment and acquired new traits. This process is called speciation, and it is responsible for the variety of species found on earth today.

The shared homologous traits of related species are evidence of a common ancestry. For example, the wings of a bat and the wings of a bird have homologous traits despite being different species. This is because they share a common ancestor, and have evolved over time to meet the environmental needs of the particular species.

Another reason why related species share homologous traits is because they live in the same geographical area. This means that they are exposed to the same environmental conditions and face similar evolutionary pressures. This means that they are more likely to share similar traits, as these are the traits which are beneficial for survival in the particular environment.
