physics

1. Define the term "momentum" in physics.

Correct answer: c

Rationale: Momentum is the product of an object's mass and velocity, describing its motion and resistance to changes in motion.

2. Which of the following joints allows for side-to-side bending movements?

Correct answer: C

Rationale: The correct answer is C: Gliding joint. Gliding joints are found where the bones meet and allow for limited side-to-side and back-and-forth movements. These joints have flat or slightly curved surfaces that glide against each other, enabling smooth motion in multiple directions. Hinge joints (A) allow for movement in one plane like a door hinge, ball-and-socket joints (B) allow for a wide range of motion in multiple directions, and saddle joints (D) allow for back-and-forth and side-to-side movements but are primarily designed for flexion and extension like the joint at the base of the thumb.

3. What is the lysosome?

Correct answer: A

Rationale: Rationale: Lysosomes are membrane-bound organelles found in animal cells that contain digestive enzymes. These enzymes help break down various cellular components, such as proteins, lipids, carbohydrates, and even foreign particles like bacteria. This process of breaking down and recycling cellular components is essential for maintaining cell health and function. Options B, C, and D do not accurately describe the function or structure of a lysosome.

4. What is the name of the monthly cycle in females that prepares the body for potential pregnancy?

Correct answer: B

Rationale: The correct answer is B: Menstrual cycle. The menstrual cycle is the monthly process in females where the lining of the uterus thickens in preparation for a potential pregnancy. If pregnancy does not occur, the lining sheds, resulting in menstruation. Ovulation is a key event within the menstrual cycle where an egg is released from the ovary, typically around the midpoint of the cycle. Implantation refers to the attachment of a fertilized egg to the uterus, which occurs after ovulation and fertilization. Gestation cycle refers to the period of pregnancy from conception to birth. Therefore, the menstrual cycle best describes the monthly process that prepares the body for potential pregnancy.

5. What is the absolute value of -7?

Correct answer: A

Rationale: Absolute value refers to the non-negative distance of a number from zero. Regardless of being positive or negative, 7 is its distance from zero.

6. The element responsible for the green color of leaves is:

Correct answer: A

Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis
