Correct Answer: C

Rationale: The milky-white fluid transported by the lymphatic vessels is called chyle. Chyle is formed in the small intestine during the digestion of fatty foods and contains a mixture of lymph and emulsified fats. Plasma is the liquid component of blood, not lymphatic fluid. Blood refers to the fluid that circulates in the cardiovascular system, not lymphatic fluid. Mucus is a slimy substance secreted by mucous membranes, not the fluid transported by lymphatic vessels.

Correct Answer: D

Rationale: Among the choices provided, carbon, in the form of diamond, has the highest melting point of any element. Diamond's strong covalent bonds between carbon atoms make it incredibly resistant to heat and pressure, giving it the highest melting point compared to tungsten, iron, and platinum. Tungsten is known for its high melting point among metals but not as high as carbon. Iron and platinum have lower melting points compared to carbon, making them incorrect choices in this context.

Correct Answer: A

Rationale: The correct difference between type 1 and type 2 diabetes lies in their underlying causes. Type 1 diabetes is caused by the body's inability to produce insulin, while type 2 diabetes is characterized by insulin resistance, where the body doesn't effectively use the insulin it produces. Insulin resistance is a key feature of type 2 diabetes, distinguishing it from type 1 where insulin deficiency is the primary issue. Choices B, C, and D are incorrect. Type 1 and type 2 diabetes can both be chronic conditions, affecting individuals of different age groups, and typically require a combination of diet, exercise, and medication for management.

Correct Answer: C

Rationale: The correct answer is Newton's Third Law. Newton's Third Law states that for every action, there is an equal and opposite reaction. In the case of rockets in space, the action is the expulsion of gas from the rocket engines, and the reaction is the forward motion of the rocket. This law explains how rockets are able to propel themselves forward in the vacuum of space. Choices A and B are incorrect because Newton's First Law (inertia) and Second Law (F=ma) do not directly explain the behavior of rockets in space. Choice D is incorrect as Newton's Third Law specifically addresses the principle behind rockets' motion in space.

Correct Answer: C

Rationale: The correct answer is C: Gluon. Gluons are the particles responsible for mediating the strong nuclear force between protons and neutrons. They are the carriers of this force. Choice A, Electron, is incorrect as electrons are negatively charged. Choice B, Photon, is incorrect as photons are chargeless particles of light. Choice D, Neutrino, is incorrect as neutrinos are neutral particles with minimal mass and weak interactions with matter, not involved in mediating the strong nuclear force between protons and neutrons.
