In humans, the gene for normal color vision, C, is dominant to the gene for red-green colorblindness,c; this trait is sex-linked

and found on the X chromosome. The gene for brown eyes, B, is dominant to the gene for blue eyes, b. Calculate the probable genotype and phenotype of the children born to blue-eyed women who is heterozygous for a color vision and a heterozygous brown-eyed man was color blind.

I don't understand these either and I have a test tomorrow on these // it is usually 50% 50% from each parent because each gene you inherit is like a coin flip, you could either get blue eyes or brown eyes.

List, in order, all the vessels blood must flow through to get from the abdominal aorta into the kidney and back to the inferior
Alenkasestr [34]

Answer:

Kidneys are the important organ of excretion. Human kidneys are bean shaped located below the rib cage. Different vessels are involved in the transportation of blood from the abdominal aorta  and back to the inferior vena cava.

The order of blood vessels are:

The blood enters in the aorta and and moves to the renal artery. Then the blood moves to the interlobar artery via segmental artery. The blood enters in the afferent glomerular arteriole from the arcuate artery and cortical radiate artery. Glomerulus receive the blood from the afferent glomerular arteriole. Then, the blood moves to the efferent glomerular arteriole. The blood then enters in the cortical radiate vein via peritubular capillaries and vasa recta. The blood moves back to the inferior vena cava from the arcuate vein, interlobar vein and renal vein.

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the choices above could be a source for t
Fudgin [204]

Answer:

The question is incomplete, the correct question is;

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the following choices could be a source for the carbon atoms in the calcium carbonate (CaCO3) molecules?

respiration by organisms such as plants, animals and microbes

burning coal

calcium ions

car exhaust

wildfires

Answer is all of the above options except calcium ions.

The source for the carbon atoms in the calcium carbonate (CaCO3) molecules include respiration by organisms such as plants, animals and microbes , burning coal , car exhaust  and wildfires.

Explanation:

Shell-builders (coral, oysters, lobsters, sea urchins, phytoplankton) utilize calcium carbonate molecules (CaCO3) to build their shells. The respiration process by organisms such as plants, animals and microbes, burning of fossil fuels, vehicle exhaust, wild fire etc produces carbon dioxide (CO2) and release it into the atmosphere. Oceans absorb carbon dioxide in the air by diffusing and dissolving it into the surface water. The amount of CO2 that dissolved in the water depends on concentrations of CO2, temperature of the water, wind, etc.

Phytoplanktons (microscopic, one-celled organisms) also bring carbon into the ocean from the air through photosynthesis, where they convert the carbon dioxide and water into glucose and other carbon compounds. These carbon compounds are consumed by the marine organisms and some carbon eventually ends up in deep seafloor sediments. The other processes which involved in the transfer of carbon from the air into deep seafloor sediments include photosynthesis , decomposition , waste products, etc.

The CO2 dissolved in the ocean combines with water molecules to produce carbonate (CO3-) ions, which then combine with calcium ions in the seawater to form calcium carbonate (CaCO3). This calcium carbonate is used by shell building organisms to build their shells, plates, inner skeletons etc.
