Answer: The pathology described in the question is "testicular torsion".
The most sensitive physical exam that is specific to this pathology is testing for reflexes. The inner thigh of the affected side when rubbed should cause the testicle to contract; but in this pathology, it does not.
Explanation:
Testicular torsion is a condition caused by the twisting of the spermatic cord, which causes a loss of blood flow to the testicle. It is the leading cause of testicular loss in adolescent boys, if no surgical intervenvention is carried out as soon as possible.
The correct answer is <u /><em>a</em><em>daption</em>. The particular environment in which a particular environment is exposed to gives it the characteristic or the ability to adapt. This is how a particular ecosystem works. It is the relationship of organisms within their environment that evolves through time in order for it to survive and propagate into more adapted kinds of species.

Answer:
The answer is B. Some organic molecules, including amino acids, could have been produced from chemical reactions on early Earth.
Explanation:
Miller-Urey Experiment:
The Miller-Urey experiment was an attempt to explain the origin of life on Earth. Miller-Urey simulated the primordial soup i.e. the environment of primitive Earth to prove the spontaneous generation of organic molecules. The conditions they introduced included:
- A methane-ammonia-hydrogen and water mixture that exactly simulated the primordial soup.
- A spark of 70,000 volts that simulated lightening.
- A temperature of 800 degree Celsius.
Observations:
- After running for 18 days, the final solution was examined for presence of organic molecules.
- Miller-Urey observed that most of the methane and ammonia had been consumed and the mixture contained carbon monoxide and nitrogen.
- The solution further contained 25 amino acids (mainly, glycine, alanine and aspartic acid)
, several fatty acids
, hydroxy acids and amide products.
The experiment concluded that simple organic compounds such as amino acids could have been formed through spontaneous generation under the Earth's primitive environmental conditions.
The axons of the olfactory sensory neurons project to the olfactory bulb in the brain. This part is found in the forbrain and is responsible for the sense of smell. Inside this bulb are spheres of tissue that are called glomeruli. They are from the ends of branching axons.
