This is the ideal question! Thanks for asking!
Before we start, let's go through a mini-review.
Photosynthesis:
The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Calvin Cycle:
A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.
Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.
So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?
In plants, carbon dioxide (CO2[tex]CO2[/tex]CO2C, O, start subscript, 2, end subscript) enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."
Carbon atoms from CO2 [tex]CO2[/tex] CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

The only people with Rh negative blood are people who have inherited two recessive alleles for this trait. But some people who are colorblind have inherited only one recessive allele for this trait. Explain why these traits are different in terms of how many recessive alleles are needed to produce the recessive phenotype. Hint: Think about the above problem and sex chromosomes versus autosomes.
The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.
What are the blood type and Color-blindness inheritance patterns?
⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.
The allele Rh+ dominates over the allele Rh-.
Genotyopes and Phenotypes are as follows,
Individuals Rh+Rh+ express the possitive phenotypeIndividuals Rh+Rh- express the possitive phenotype Individuals Rh-Rh- express the negative phenotype.To express Rh-, a person must inherit two recessive alleles from their parents.
⇒ Color-blindness is an X-linked condition coded by a recessive allele.
As most sex-linked genes, it is transmitted together with the X chromosome.
The phenotype depends on the number of recessive alleles and the sex of the person.
Genotyopes and Phenotypes are as follows,
X⁺X⁺ women have normal sight.X⁻X⁻ women are completely color-blinded X⁺X⁻ women are partially color-blinded. X⁺Y Men are not color-blinded X⁻Y Men are color blinded.In this case, only one recessive allele is enough to express the affection.
In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

Describe and explain how blood flows from the foot to the lungs.
Answer:
lungs:
The blood first enters the right atrium.
The blood then flows through the tricuspid valve into the right ventricle.
When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
It then leaves the lungs to return to the heart through the pulmonary vein.
The blood enters the left atrium.
It drops through the mitral valve into the left ventricle.
The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.
Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.
The vena cavas pump blood into the right atrium and the cycle begins all over again.

Which of the following is NOT a behavior of parental care?
A. Feeding
OB. Courtship displays
C. Protection from predators
D. Incubation of eggs
Parental care is the energy investment in looking after the progeny to ensure reproductive success, at the sacrifice of feeding, mating, and being save. The option is B. Courtship displays.
What is parental care?Parenting is a caring behavior chosen by some species in which parents invest energy in looking after their offspring to ensure their survival and hence, their reproductive success.
K-strategists are the species that perform parenting.
Animals must optimize the invested energy in growing, surviving, reproducing, and leaving fertile offspring. They must ensure the perpetuity of the species. The best way to do it is by reaching sexual maturity, mating, and leaving progeny that also reaches their fertile age. So species choose how to do it and where to invest more energy.
K strategists take care of their offspring and invest too much energy in doing it.
Parents must feed them, an activity that requires most of their energy to produce food or look for it. They must protect their progeny from potential opportunistic predators, so they need to be near the whole time. They need to teach behaviors and habits.And so many other things that require energy investment.
So, when parents take care of their offspring, the energy usually destined for survival and mating activities is now destined for parenting.
Often, parents can not feed because they can not leave their offspring alone. They face predators putting themselves in danger of being hurt. They can not mate even if they are in the reproductive season.
According to this framework, the correct option is Courtship displays. Option B. This is a typical pre-mating behavior in which sexual selection plays a significan role.

How does mitochondrial structure contribute to aerobic metabolism, particularly in the integration of the citric acid cycle and electron transport?.
The reduced electron carriers generated by the citric acid cycle are restricted to the matrix by mitochondrial structure. There, they are adjacent to the respiratory complexes of the electron transport chain, which will transfer the electrons from the carriers made by the TCA cycle to oxygen, the final recipient of electrons and hydrogens.
What is the role of mitochondria in the citric acid cycle and electron transport chain?
Citric Acid Cycle:
The pyruvate molecules generated at the conclusion of glycolysis are carried into mitochondria, which are locations of cellular respiration, in eukaryotic cells. By eliminating a carbon dioxide molecule in the mitochondria, pyruvate is converted into a two-carbon acetyl group, which is then taken up by the carrier substance coenzyme A. (CoA). The end product is known as acetyl CoA.
The citric acid cycle occurs in the matrix of the mitochondria in eukaryotic cells. The eight phases of the cycle are a sequence of chemical processes that result in the production of two molecules of carbon dioxide, one molecule of ATP, and the reduced versions of NAD+ and FAD+, known as NADH and FADH2, which are crucial coenzymes for cell function. Because the NADH and FADH2 generated must transport their electrons to the system's next pathway, which uses oxygen, part of this is regarded as an aerobic pathway. This transmission is not possible without oxygen.
Electron Transport Chain:
However, the majority of the ATP produced during the aerobic breakdown of glucose does not come from these mechanisms. Instead, it results from a procedure that starts with the transfer of electrons through a series of chemical events to an ultimate electron acceptor, oxygen. Both eukaryotic organisms' mitochondrial inner membranes and prokaryotic organisms' inner cell membranes contain specific protein complexes where these processes occur. A gradient of electrochemistry is produced across the inner mitochondrial membrane by harnessing the energy of the electrons. ATP is produced using the potential energy of this gradient. This entire procedure is known as oxidative phosphorylation.
The sole aspect of metabolism that employs ambient oxygen is the electron transport chain, which is the final stage of aerobic respiration. The electron transport chain is made up of the aggregation of the four protein complexes I through IV as well as any related mobile, accessory electron carriers.
