• Question 51:

  A ball is tied to a pole with a rope and is moving in a circle with constant speed.

  Which of these statements about the ball is true?

  A. Force is acting away from the center of circle.
  B. Force is acting at a tangent to the circle.
  C. There is no acceleration.
  D. There is force acting toward the center of circle.
  D. There is force acting toward the center of circle.

• Question 52:

  

  What is the possibility that the offspring produced will have brown eyes? B = alleles for brown eyes; g = alleles for green eyes

  A. 100%
  B. 75%
  C. 50%
  D. 25%
  B. 75%

  ---

  Dominant genes are always expressed when both alleles are dominant (BB) or when one is dominant and one is recessive (Bg). In this case, 3/4 or 75% will have brown eyes.

• Question 53:

  Which of the following is an example of a tissue?

  A. xylem
  B. liver
  C. mammal
  D. hamstring
  A. xylem

  ---

  A xylem is an example of a tissue. A liver is an organ, a mammal is a type of organism, and a hamstring is a muscle.

• Question 54:

  

  In this diagram of the brain, some of the labels are missing.

  What should the labels be?

  A. 1. cerebral cortex, 2. thalamus, 3. medulla oblongata, 4. pons
  B. 1. cerebellum, 2. grey matter, 3. thalamus, 4. hindbrain
  C. 1. forebrain, 2. midbrain, 3. brain stem, 4. pons
  D. 1. hippocampus, 2. fornix, 3. midbrain, 4. pons
  A. 1. cerebral cortex, 2. thalamus, 3. medulla oblongata, 4. pons

• Question 55:

  Which of these organs is made up of epithelial tissue?

  A. the skin
  B. the liver
  C. the heart
  D. the brain
  A. the skin

• Question 56:

  The law of conservation of mass states that __________.

  A. The total mass of all products of a chemical reaction is independent of the total mass of all the reactants. They are not related.
  B. The total mass of all products of a chemical reaction is equal to the total mass of all the reactants.
  C. The total mass of all products of a chemical reaction is more than the total mass of all the reactants.
  D. The total mass of all products of a chemical reaction is less than the total mass of all the reactants, because some mass coverts to energy during reaction.
  B. The total mass of all products of a chemical reaction is equal to the total mass of all the reactants.

• Question 57:

  Which of these statements regarding the "oxygen debt" created during heavy exercise is true?

  A. Oxygen debt is created due to build-up of acetic acid in the muscles, which needs a high level of oxygen to be oxidized.
  B. Oxygen debt is created due to build-up of lactic acid in the muscles, which needs a high level of oxygen to be oxidized.
  C. Oxygen debt is created due to build-up of lactic acid in the liver, which needs a high level of oxygen to be stored.
  D. Oxygen debt is created due to build-up of lactic acid in the muscles, which needs a high level of carbon dioxide to be oxidized.
  B. Oxygen debt is created due to build-up of lactic acid in the muscles, which needs a high level of oxygen to be oxidized.

• Question 58:

  A man of mass 60 kg, runs up the stairs of total height 5 meters in 4 seconds.

  How much power is exerted by the man?

  A. 800W
  B. 750 W
  C. 250W
  D. 1000W
  B. 750 W

• Question 59:

  By which gland in the body is produced follicle-stimulating hormone (FSH), which is responsible for maturation of follicles in the ovary?

  A. corpus luteum
  B. ovary
  C. anterior lobe of pituitary gland
  D. posterior lobe of pituitary gland
  C. anterior lobe of pituitary gland

• Question 60:

  Prokaryotic and eukaryotic cells are similar in having which of the following?

  A. Presence of a nucleus
  B. Protein-studded DNA
  C. Integral membrane proteins in the plasma membrane
  D. Membrane-bound organelles
  D. Membrane-bound organelles

  ---

  Both prokaryotes and eukaryotes interact with the extracellular environment and use membrane-bound or membrane-associated proteins to achieve this. They both use diffusion and active transport to move materials in and out of their cells. Prokaryotes have very few proteins associated with their DNA, whereas eukaryotes' DNA is richly studded with proteins. Both types of living things can have flagella, although with different structural characteristics in the two groups. The most important differences between prokaryotes and eukaryotes are the lack of a nucleus and membrane-bound organelles in prokaryotes.
