The best explanation for the change in the bass size is Natural Selection.

The presence of a predator made the larger bass more susceptible and so more likely to be preyed upon. Larger bass would gradually be eliminated from the population through selective breeding, allowing smaller fish to procreate and pass on their genes.

Over several generations, this would cause the population's average size to decline. Natural selection is therefore the most plausible cause of the variation in bass size.

Sperm, prostate fluid, and seminal fluid mix together to form semen in the ejaculatory duct

The ejaculatory duct is a tube that connects the vas deferens and seminal vesicles to the urethra. During ejaculation, the muscles surrounding the ejaculatory duct contract, pushing the mixture of fluids into the urethra and out of the body. The seminal vesicles produce a majority of the seminal fluid, which contains fructose, proteins, and other nutrients to nourish and protect the sperm.

The prostate gland secretes a thin, milky fluid that helps to activate and mobilize the sperm. The vas deferens, which transports the sperm from the testes, joins with the seminal vesicles to form the ejaculatory duct, where the fluids mix together before being expelled from the body during ejaculation. Overall, the process of semen production is complex and involves the contribution of several different organs and fluids. Sperm, prostate fluid, and seminal fluid mix together to form semen in the ejaculatory duct.

Heme, a component of hemoglobin found in aged red blood cells, is broken down in the liver into heme and globin, through a process called heme catabolism.

When red blood cells reach the end of their lifespan, typically around 120 days, they are engulfed by macrophages in the spleen, liver, and bone marrow. Inside these macrophages, hemoglobin is separated into heme and globin.

The heme is then transported to the liver, where it undergoes a series of enzymatic reactions to be decomposed into biliverdin, a green pigment, by an enzyme called heme oxygenase. Biliverdin is subsequently reduced to bilirubin, a yellow pigment, by biliverdin reductase. Bilirubin is then conjugated with glucuronic acid by the enzyme UDP-glucuronosyltransferase, forming conjugated bilirubin, which is more water-soluble and can be excreted more easily by the body.

Conjugated bilirubin is secreted into bile by the liver and then released into the small intestine. In the intestine, bacteria convert bilirubin to urobilinogen. Some of the urobilinogen is absorbed back into the bloodstream, while the rest is transformed into stercobilin and excreted in feces, giving it a brown color. A small amount of urobilinogen is converted to urobilin in the kidneys, which gives urine its characteristic yellow color.

Overall, the decomposition of heme in the liver plays a critical role in the body's ability to recycle and eliminate aged red blood cells and their components.

Glucose reabsorption occurs in the proximal tubule of the nephron. The majority of the filtered glucose undergoes reabsorption by the proximal tubule, the first segment of the nephron after the glomerulus.

A little molecule called glucose is freely filtered into the proximal tubule by the glomerulus. However, specialized transport proteins found in the membranes of the tubular cells allow the majority of the filtered glucose to be reabsorbed back into the bloodstream.

The sodium-glucose cotransporter 2 (SGLT2) is the main transporter in charge of reabsorption of glucose in the proximal tubule. This protein, which actively transfers glucose from the tubular fluid into the cell utilising the energy from the electrochemical gradient of sodium ions, is found on the apical membrane (luminal side) of the proximal tubular cells.

Glucose is transferred from the blood side of the tubular cell across the basolateral membrane and into the interstitial fluid, where it can enter peritubular capillaries and return to the bloodstream.

The reabsorption of glucose is normally almost complete, leaving only a trace amount of glucose in the urine. However, glucose may show up in the urine (glucosuria) if the filtered glucose load exceeds the transporters' capacity, as might happen in diabetes mellitus.

Osteoblasts, osteoclasts, and osteocytes are three different types of bone cells. Osteoblasts are responsible for bone formation and the deposition of new bone tissue. Osteoclasts are responsible for bone resorption and the breakdown of bone tissue. Osteocytes are mature bone cells that are embedded in the mineralized bone matrix.

The difference between osteoblasts, osteoclasts, and osteocytes is as follows:

1. Osteoblasts are cells responsible for bone formation. They synthesize and secrete the bone matrix.
2. Osteoclasts are cells responsible for bone resorption. They break down the bone matrix, releasing minerals back into the bloodstream.
3. Osteocytes are mature bone cells that maintain the bone matrix and regulate bone remodeling.

Osteoclasts work with parathyroid hormone (PTH) to carry out the PTH function, which is to increase blood calcium levels. PTH stimulates osteoclast activity, leading to bone resorption and the release of calcium into the bloodstream.

The role of vitamin D is to promote calcium absorption in the gut, regulate calcium and phosphate levels, and support bone mineralization. It also plays a role in bone remodeling by stimulating osteoblast and osteoclast activity.

Calcitonin is a hormone that works in opposition to PTH. Its primary function is to lower blood calcium levels by inhibiting osteoclast activity, promoting calcium deposition in bones, and increasing calcium excretion by the kidneys.

The law of inheritance demonstrated by this statement is Mendel's Law of Segregation.

Mendel's Law of Segregation states that during the formation of gametes, the two alleles for a single gene separate, so that each gamete receives only one allele. In the given scenario, an organism has a single gene, and each gamete receives a single allele for this gene. This perfectly aligns with the Law of Segregation.This is because the gene can only exist in two different forms (alleles) and they must separate during the formation of gametes. When fertilization occurs, the new individual will inherit two alleles for each gene, one from each parent.

In summary, the law of segregation explains how the alleles of a gene separate during gamete formation and why each gamete only receives one allele. This is demonstrated in the statement that if an organism has only a single gene, each gamete receives a single allele for that gene.
