Scientists are studying cell-to-cell communication in a human spleen. To predict what triggers cells-to-cell communication. As a part of the mononuclear phagocyte system, it degrades hemoglobin that has been removed from senescent red blood cells.

An almost universal organ in animals is the spleen. It looks like a large lymph node and performs largely as a blood filter. An essential organ for the immune system and red blood cells is the spleen (erythrocytes). Iron is recycled while old red blood cells are discarded and a blood reserve is kept that may be helpful in the event of hemorrhagic shock. While the globin portion of hemoglobin is broken down to its individual amino acids, the heme portion is transformed into bilirubin, which is expelled in the liver.

The complete question is:

Scientists are studying cell-to-cell communication in a human spleen. How would scientists most likely use technology during this study?

a) To draw a diagram showing how cellular communication occurs

600 cubes make up the surface of the larger cube.

This can be calculated by multiplying the height, width, and length of the cube together and subtracting two. For example, 10 x 10 x 10 = 1000. 1000 - 2 = 998. 998/2 = 499. 600 cubes make up the surface of the larger cube.

The calculation is based on the formula: Surface area = (2 x length x width) + (2 x length x height) + (2 x width x height). In this case, the length, width and height are all 10. This formula can be written as 2 x 10 x 10 + 2 x 10 x 10 + 2 x 10 x 10 = 600.

To confirm this answer, the volume of the cube can also be calculated by multiplying the length, width, and height together. In this case, 10 x 10 x 10 = 1000 cubes. If two cubes are subtracted from this number, 600 cubes remain, which is the surface area of the larger cube.

The energy for the attachment of a third phosphate to ADP comes from a process called oxidative phosphorylation.

This is a process in which energy stored in food molecules is harnessed to produce ATP, the energy currency of the cell. Oxidative phosphorylation takes place in the mitochondria, the powerhouses of the cell, and involves the electron transport chain, a series of reactions in which electrons are passed down a series of molecules to ultimately drive the production of ATP.

At the end of the chain, the electrons are used to reduce oxygen to form water, releasing the energy used to drive the ATP synthesis. Using this energy, a third phosphate is added to ADP to create ATP.

This tells us that the trait of being able to taste PTC is likely a polygenic trait, meaning that it is not controlled by a single gene with two alleles (dominant and recessive) but by multiple genes, each with multiple different alleles. It is possible that certain alleles are more common than others, but this does not necessarily mean that they are dominant or recessive.

The classic model of dominant/recessive inheritance relies on the assumption that a trait is determined by a single gene with two alleles, one of which is dominant and one of which is recessive. However, in the case of the ability to taste PTC, it is clear that this trait is not determined by a single gene with two alleles. In fact, it is likely determined by multiple genes, each with multiple different alleles.

This means that it is not possible to determine which alleles are dominant or recessive, as it is likely that different combinations of alleles can result in the ability to taste PTC. Therefore, the classic model of dominant/recessive inheritance does not apply to the ability to taste PTC.
