Snail is the least related to the others, evolutionarily comparing to the following animals.

It is believed that the first land snail evolved around 350 million years ago, when plants required extremely wet conditions. snail is a mollusk type of animal. Survival on land meant a period of unfavorable conditions, with climatic changes affecting the snail's body, which is still mostly water. There is evidence of primitive gastropods dating back to the late Cambrian period; all land snails have made numerous adaptations to survive. Their main adaptation is the transition from aquatic to terrestrial (or land) organisms. They accomplished this by losing their gills and developing air-breathing lungs.

Gonorrhea is a sexually transmitted disease, the male complains of swollen testicles and the female complains of yellowish vaginal discharge.

Gonorrhea in males can result in a painful infection in the testicles and prostate gland, which in a small percentage of instances may impair fertility.

In a small percentage of cases, untreated gonorrhea can spread through the bloodstream and result in life-threatening infections in other body areas (sepsis).

Therefore, for a number of reasons, women in particular are more likely than males to get gonorrhea, syphilis, and chlamydia.

The purpose of meiosis is to produce gametes or sex cells. During meiosis, four daughter cells are produced, each of which is haploid (containing half as many chromosomes as the parent cell).

What is Meiosis?

Meiosis contains two distinct cell divisions, which means that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis. The cell grows, copies its chromosomes, and prepares for division during the G1​​ phase, S phase, and G2 phase of interphase.

Rapid, dependable, and uncontrollable motor reactions to stimuli are known as reflexes.

Neural pathways called reflex arcs are made up of five fundamental parts.

Learned reflexes include things like riding a bike and operating a vehicle.

The body has inherent reflexes that function as a defense mechanism.

What are intrinsic reflexes?

The quadriceps reflex is an example of an intrinsic reflex. In contrast, extrinsic reflexes have receptors and effectors that are located in separate organs (e.g., the oculovestibular reflex).

Reflexes are actions made up of comparatively basic behavioral segments that typically happen as quick, immediate reactions to certain stimuli that are specifically connected with them.

The structures found within a skeletal muscle.

Skeletal striated muscle tissue is formed by bundles of very long, multinucleated cylindrical fibers known as skeletal striated muscle fibers. These bundles are surrounded by the epimysium, an outer membrane of dense connective tissue. Septa of very thin connective tissue, called perimysium, depart from these membranes, through which blood vessels enter the muscles. They are muscles of voluntary movement.

Myosin is made up of two subunits, light meromyosin and heavy meromyosin. The light meromyosin corresponds to the largest portion of the rod, while the heavy meromyosin is composed of the smallest part of the rod next to the globular projection.

The sarcolemma consists of a cell membrane, called the plasma membrane, and a lining of a thin layer of polysaccharide material, with many thin collagen fibrils.

small pedunculated bodies may undergo torsion.
The testis lies outside the body cavity in the scrotum where it is maintained at a temperature 2–3°C lower than the body temperature. Failure to descend into the scrotum causes failure of spermatogenesis.

Blood supply
The testis and epididymis are suspended by the spermatic cord containing their arterial blood supply, venous and lymphatic drainage and nerve supply. The testis develops in the L2/L3 vertebral region and drags its vascular, lymphatic and nerve supply from this region to the scrotum.
Testicular and renal pain may mimic each other. Testicular pain hence can radiate to the loin and renal pain often is referred to the scrotum.

The arterial supply is via the testicular artery which is a branch of the abdominal aorta given off just below the level of origin of the renal arteries. The venous drainage is via the pampiniform plexus of veins which become a single testicular vein before terminating in the inferior vena cava on the right side and the left renal vein on the left side.
The lymphatics of the testis and epididymis accompany the blood vessels and drain into the para-aortic lymph nodes. Upper abdomen must therefore be palpated when searching for secondary lymphatic spread from a carcinoma of the testis.

The spermatic cord
The spermatic cord contains the ductus deferens (vas deferens), the testicular artery and the pampiniform plexus of veins. Other structures in the cord are the cremasteric artery, the artery to the vas, nerve to the cremaster, sympathetic nerves and the lymphatics of the testis and epididymis. Because of its passage through the inguinal canal the spermatic cord acquires three coverings, i.e. the external spermatic fascia from the external oblique aponeurosis at the superficial inguinal ring, the cremasteric muscle and fascia from the internal oblique, and the internal spermatic fascia from the transversalis fascia at the deep inguinal ring.

Varicocoele is a condition caused by dilated tortuous pampiniform plexus of veins. The condition, which may be felt as a ‘bag of worms’ while palpating the scrotum, is more commonly present on the left side. As the left testicular veins drain into the left renal veins it may be a sign of a malignant tumour in the left kidney.

Viruses are complex assemblages of molecules that include proteins, nucleic acids, lipids, and carbohydrates; but, on their own, they are unable to perform any function and must first infect a living cell in order to become active. There would be no possibility of viral reproduction if cells did not exist. Consequently, viruses do not qualify as living beings.

ATP production by the phosphagen system increases and decreases rapidly following the start of the exercise period.

What is ATP?

Adenosine triphosphate (ATP) is the cellular energy source for usage and storage. An adenine-based nitrogenous base, ribose sugar, and three serially bound phosphate groups make up the nucleoside triphosphate structure of ATP. When macromolecules like proteins and lipids are moved into and out of the cell, ATP is an essential component of the process. Active transport mechanisms are able to move these molecules over a concentration gradient because the hydrolysis of ATP supplies the energy needed. The source of energy in a cell is ATP. Cells are able to safely store energy in tiny packets and only release it when absolutely necessary. In other words, ATP bridges the gap between activities that need energy, like synthesis and those that release energy, like the breakdown of food.

In 1960s, eutrophication of the lake was largely addressed by limiting levels of phosphorus.

The largest of the three significant lakes in King County, Lake Washington is also the second-largest natural lake in the state of Washington. In the 1960s, phosphorus concentrations were found to be 70 parts per billion. That was more than enough to support the large growth of algae that discoloured the water and washed up on the shore where it rotted and smelled.

Between 1941 and 1963, the lake received increasing amounts of secondary treated sewage, which led to eutrophication and a decline in the lake's water quality. Eutrophication, often known as the overgrowth of algae and big aquatic plants, is a process that can be brought on by an excess of phosphorus. High phosphorus levels can also cause algal blooms, which can create toxins that are dangerous to both human and animal health.
