A drop of blood returning from the big toe would enter the heart through what vessel?
O Pulmonary veins
O Coronary sinus
Inferior vena cava
O Azygous vein
O Superior vena cava
Answer:
The inferior vena cava
Explanation:
A drop of blood returning from the big toe would enter the heart through the inferior vena cava.
The inferior vena cava is a blood vessel that is located near the heart, with the aim of receiving the blood that has already traveled through the abdominal cavity and the lower extremities.
The inferior vena cava originates at the level of the pelvis, when the external iliac vein and the hypogastric vein come together to create a system that collects the blood waste that has already traveled both legs.Therefore, together with the superior vena cava and the coronary sinus, they are the ones that carry blood to the right atrium.Therefore, we can conclude that the superior vena cava collects deoxygenated blood that comes from the abdomen, pelvis, and lower limbs.

In the universal ABO blood grouping system, there are four phenotypes—A, B, AB, and O—which are determined by three different alleles. The presence of three alleles in the ABO blood grouping system is an example of ____.
Answer:
The correct answer is - autosomal codominant inheritance (due to multiple alleles).
Explanation:
Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.
The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.

Describe how photosynthesis and cellular respiration play a role in cycling carbon through all four spheres of the earth be sure to include the following in your explanation that puts in outputs of photosynthesis the inputs and outputs of cellular respiration and the biosphere atmosphere hydrosphere and geosphere
Answer:
Carbon is an element and is part of the oceans, air, rocks, soils and living things, it does not stay in one place.
In the atmosphere, it combines with oxygen in a gas called carbon dioxide (CO2). With the help of the sun, through photosynthesis, carbon dioxide is extracted from the air and converted into food.
Through food chains, carbon from plants goes to the animals that feed on them. Animals that eat other animals also obtain carbon through their food.
When plants and animals die, their bodies, wood, and leaves decompose in the soil. Part of the decomposed matter is buried and after millions and millions of years, it becomes fossil fuel.
The carbon from fossil fuels goes into the atmosphere when the fuel is burned. When humans burn fossil fuels to power their factories, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere in the form of carbon dioxide gas. Every year, five and a half billion tons of carbon are released in the form of fossil fuels burned.
The oceans and other bodies of water absorb some of the carbon from the atmosphere. It dissolves in water. Marine animals use carbon to create the material for their skeletons and shells.
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere. When carbon is deposited on the seabed, it is stored outside the carbon cycle for long periods of time. The amount of limestone deposited in the ocean depends in some way on the amount of shallow, tropical and warm oceans on the planet, because that is where limestone-producing organisms, such as corals, proliferate. Carbon can be released back into the atmosphere if the limestone melts or undergoes metamorphosis in a subduction zone.

Denaturing is the process of interrupting a protein's structure so that it no longer functions. Which level of structure is NOT affected by denaturing a protein
Answer:
The primary structure is not affected by denaturing a protein.
Explanation:
Denaturation can be defined as the process in which a protein loses its three-dimensional structure.
This would mean the protein losses its quaternary, tertiary and secondary structure.
However the aminoacid sequence (the primary structure) remains the same.

Suppose that the genome of an organism is 23% adenine (A). What should be true about the organism's genome?
a) its genome is 23% guanine (G)
b) nothing else can be inferred
c) its genome is 23% thymine (T)
d) its genome is 23% cytosine (C)
e) its genome is 23% uracil (U)
Answer:
The correct answer would be - c) its genome is 23% thymine (T)
Explanation:
The rule of Chargaff says that the amount of the adenine (A) and thymine (T) is almost equal and guanine (G) to cytosine (C) and also the amount of A and T should be equal to the amount of the G and C.
So, A= 23 % then T must be 23 %
Then, A+T = 46%.
The left 54% should be divide by 2, G and C that would be 27 %.
So, the correct option is C.
If the genome of an organism is 23% adenine (A), then its genome is 23% thymine (T).
DNA:
DNA or deoxyribonucleic acid is a biological molecule that stores genetic information in living cells. DNA is structurally made up of nucleotides namely: adenine, thymine, cytosine and guanine. According to Erwin Chargaff, the amount of adenine in the DNA is equal to thymine while the amount of guanine is equal to cytosine i.e. A - T, G - C. Therefore, If the genome of an organism is 23% adenine (A), this means that its genome is also 23% thymine (T).Learn more about DNA composition at: https://brainly.com/question/13049777?referrer=searchResults
