The ability of carbon to catenate and the fact that it has low bond energy accounts for the fact that it forms large, complex structures of organic compounds.

The complex organic compounds are those compounds that are composed of carbon but they do have a very large macromolecular structure. These compounds are found in the body as well as are useful in the industry. A common example of a very large macromolecule which plays a very important role in the body is the biological molecule that we call cholesterol which is largely macro molecular.

There are several reasons that enables carbon to form these kinds of large and complex organic compounds;

1) Low bond energy: The carbon to carbon bond energy is very low and this enables carbon to link to itself many times.

2) Carbon does catenate: The ability of carbon to catenate makes the carbon atom able to link to itself in such a way that gives an infinitely large chain of carbon atoms.

3) Carbon does bond easily to hydrogen: The fact that the bond energy of the carbon hydrogen bond is low also makes it possible for carbon to bond to hydrogen in these large organic molecules.

4) Carbon bonds with electronegative atoms: It is common to observe that carbon is also able to bond with highly electronegative atoms thereby forming more compounds.

Knuckle-walking is only found in primates with longer arms than legs.

In knuckle-walking, the forelimbs keep the fingers in a partly extended position so that the body weight may push down via the knuckles on the ground. This kind of walking is used by chimpanzees, gorillas, anteaters, and even platypuses. This happens in primates with longer arms than legs.

Knuckle walking is beneficial for activities other than ground movement. The gorilla uses its fingers to manipulate food, and chimpanzees use their fingers to manipulate food and climb.

Anteaters and pangolins have strong claws on their fingers that are used to pry apart social insect mounds. Knuckle walking is utilized to avoid tripping since the platypus's fingers contain webbing that extends past the fingertips to help with swimming.

From the options given, the best statement to explain the impact of convection on the atmosphere is: D. Warm air rises upwards. Convection in the atmosphere directly impacts cloud formation.

Convection is the process that includes movement within a liquid or gas driven by differences in temperature and density. Convection on our atmosphere is very crucial in water cycles. Through the convention, energy from the hotter areas will be redistributed to the cooler areas. It affects wind direction and helps aid temperature circulation on Earth.

Convection also affects the weather. As the sun heats Earth’s surface, the air heats up and rises. Once this air cools down in the atmosphere, Cumulus clouds will form and produces rain eventually.

The air moves to the lungs during inspiration. The alveolar pressure must be lower than the atmospheric pressure for air to move to the lungs.

The lungs can take in air thanks to this difference in pressure. Inhaling, sometimes referred to as inspiration, is the initial phase. Inhalation causes the diaphragm to tighten and pull downward.

The H-W equilibrium theory states that, considering a diallelic gene, the addition of allelic frequencies equals 1 (p + q = 1) and the addition of genotypic frequencies equals 1 (p² + 2pq + q² = 1). The percentage of the population that is heterozygous (Ss) for the sickle-cell gene is 42%.

The Hardy-Weinberg equilibrium theory states that in populations that are in equilibrium, their allelic and genotypic frequencies remain the same generation after generation.

These populations are not evolving. No evolutive forces or other events that affect their frequencies are acting on them.

Assuming a diallelic gene that codes for a trait,

⇒ Allelic frequencies are represented as p and q,

The addition of the allelic frequencies equals 1

p + q = 1.

⇒ The genotypic frequencies after one generation are

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Now let us answer the question,

Sickle cell anemia is an autosomal recessive disorder, so individuals expressing this phenotype are homozygous recessive, ss.

We need to calculate the frequency of the heterozygous genotype by using the frequency of homozygous recessive individuals.

The genotypic frequency of individuals born with the disorder is 9%, so

q² = 9% = 0.09

So, knowing the homozygous recessive frequency, we will calculate the recessive allele frequency, q.

If q² = 0.09, then q = √q² = √0.09 = 0.3

So the recessive allele frequency is q = 0.3

Now we need to get the dominant allele frequency, and we will get it by clearing the equation p + q = 1

p + q = 1

p + 0.3 = 1

p = 1 - 0.3

p = 0.7

So, the dominant allele frequency is p = 0.7.

The dominant genotypic frequency is p² = 0.7² = 0.49

Up to here, we know that,

With these data, we can calculate the heterozygous genotypic frequency -2pq- by clearing the following equation,  

p² + 2pq + q² = 1

0.49 + 2pq + 0.09 = 1

2pq = 1 - 0.49 - 0.09

2pq = 0.42

Assuming the population is in hardy-weinberg equilibrium, the frequency of heterozygous individuals Ss = 2pq = 0.42 = 42%.

The process of photosynthesis is commonly written as:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.

The light-dependent and light-independent reactions are the two steps. The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.

In higher plants, algae, and cyanobacteria, a membrane protein supercomplex called photosystem II (PSII) carries out the first step of photosynthesis. To accelerate a transmembrane charge separation, it absorbs sunlight.

To begin photosynthesis, a photon interacts with photosystem II's antenna pigments. The hydrogen ions are pumped into the interior of the thylakoid by the electron transport chain after the energy passes through the reaction center, which contains chlorophyll a. A significant ion concentration is created by this action.

During photosynthesis, it is the conversion of ADP to ATP utilizing solar energy. In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.

Chloroplasts include ferredoxin (Fd), an enzyme that facilitates electron transport and has an iron-sulfur cluster. When being oxidized or reduced, its iron atoms accept or release electrons, which is how it participates in the photosynthesis process.

Hydrogen ions, oxygen ions, and electrons are separated from water. Within the thylakoid lumen, oxygen and protons created by the splitting of water are discharged.

Cyclic photophosphorylation, is described as the production of ATP related to electron transport that is only activated by Photosystem I (700 nm). The particular Photosystem II inhibitors CMU, DCMU, and orthophenanthroline have no impact on this process.

The enzyme that produces ATP via chemiosmosis is called ATP synthase. It permits protons to cross the membrane and generates ATP by phosphorylating adenosine diphosphate (ADP) with the free energy difference. In addition to mitochondria and chloroplasts, most bacteria and archaea also produce ATP by chemiosmosis.
