physics

1. What happens to the momentum of an object when there is no external force acting upon it?

Correct answer: c

Rationale: In the absence of external forces, momentum remains constant due to the conservation of momentum.

2. What enzyme plays a key role in breaking down carbohydrates in the small intestine?

Correct answer: C

Rationale: Amylase, produced by the pancreas and salivary glands, breaks down carbohydrates into simple sugars like glucose.

3. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?

Correct answer: A

Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.

4. Peppered moths in England came in two color variations – light and dark. After the Industrial Revolution, the population shifted towards more dark moths. This is an example of:

Correct answer: B

Rationale: Rationale: The phenomenon of peppered moths in England shifting towards more dark moths after the Industrial Revolution is a classic example of natural selection acting on pre-existing variation. Before the Industrial Revolution, light-colored moths were better camouflaged against lichen-covered tree trunks, which were common in the environment. However, with the increase in industrial pollution, the tree trunks became darker due to soot, making dark-colored moths better camouflaged and less likely to be eaten by predators. As a result, the population shifted towards more dark moths over time. This change in the moth population was driven by the selective pressure of predation, demonstrating the process of natural selection favoring individuals with traits that provide a survival advantage in a changing environment.

5. The immune response can be categorized into two main branches:

Correct answer: A

Rationale: Rationale: - The immune response can be broadly categorized into two main branches: the humoral immune response and the cellular immune response. - The humoral immune response involves the production of antibodies by B cells and is primarily responsible for defending against extracellular pathogens such as bacteria and viruses in the bloodstream and tissues. - The cellular immune response involves the activation of T cells, which can directly kill infected cells or help coordinate the immune response. This branch is crucial for combating intracellular pathogens like viruses and some bacteria. - Options B, C, and D do not accurately represent the main branches of the immune response and are therefore incorrect.

6. How is power related to energy?

Correct answer: b

Rationale: Energy is related to the amount of work done or the capacity to do work, while power measures the rate at which work is done or energy is transferred.
