The urinary system is a specialized organ that supports the exchange of water and electrolytes between the body and the environment. It includes kidneys, ureters, bladder, and urethra which perform a function like passage, storage and voiding of urine. It helps the body to get rid of liquid waste (urea) and also control the blood pressure and pH.

It helps the body to get rid of liquid waste (urea) and also control the blood pressure and pH.

Expert Solution & Answer

Answer to Problem 1RAC

The correct answer is option (d) regulation of vitamin A synthesis.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d). Regulation of vitamin A synthesis. Vitamin A is taken from the food it is not synthesis by the body, whereas kidney plays a very important role in the synthesis of vitamin D. it is needed for controlling blood calcium. So, the correct answer is option (d).

Explanation for incorrect answer:

Option (a). Regulation of blood volume. It helps in regulating the blood volume by secreting and absorbing the essential components (water, solute). It helps in producing either a large volume of diluted urine or a small volume of concentrated urine. So, this is an incorrect option.

Option (b). Regulation of solute concentration in the blood. It helps in regulating the solute concentration by reabsorbing solutes like sodium, chloride, potassium, calcium, and carbonates ions. So, this is an incorrect answer.

Option (c). Regulation of pH of the extracellular. The pH of the blood is regulated by secreting a variable amount of hydrogen ion. So, this is an incorrect answer.

Option (e). Regulation of red blood cell synthesis. Kidney secretes a hormone called erythropoietin which helps in regulating the synthesis of red blood cells in the bone marrow. So, this is an incorrect answer.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
