• Okay teacher!

• I am too lazy for this

Multiple Choice

A cell with a single set UNPAIRED chromosomes is known as

• diploid

• haploid

• bivalent

• homologous

Multiple Choice

Which of the following statement is TRUE about mitosis

• It maintains the same chromosome number in the daughter cells as in the parent cell.

• It is the last phase of interphase.

• It regulates the transfer of genetic information from one daughter cell to another

• It moves homologous chromosomes to opposite poles.

Multiple Choice

There are 36 chromosomes in the nucleus of an organism. How many chromosomes are formed in daughter cell through mitosis?

• 18

• 36

• 72

• 144

​MITOSIS

​At the end of mitosis, the two daughter cells will be exact copies of the original cell.

​

​

Since there are 36 chromosomes, hence the chromosomes formed at the daughter cells will also be 36

Multiple Choice

In which stage, does the division of cytoplams start?

• Prophase

• Metaphase

• Anaphase

• Telophase

• Carbon dioxide + water

• Lactic acid

• Ethanol

• 38 ATP

Multiple Choice

The equation below shows anaerobic respiration in yeast

Glucose⟶  P + carbon dioxide + energy

What is P?

• Ethanol

• Lactic acid

• Oxygen

• Water

Multiple Choice

A complete breakdown of per mole glucose in aerobic respiration will generates ____ molecules of ATP

• 38

• 36

• 100

• 2

Multiple Choice

Which of the following is true about the structural adaptation of the tracheoles in insects for gaseous exchange?

I. The large number of tracheoles provide large surface area

II. The tracheoles are close to each body cell

III. The tracheoles have thin permeable wall

IV. Gaseous exchange takes place directly from the tracheoles into the cell

• I and II

• III and IV

• I, III and IV

• All of the above

Multiple Choice

Which of the following are adaptations of a fish gill filaments for respiration?

I. The gill filaments has thin membrane to filter the bacteria in the water.

II. The gill filaments are supplied with numerous blood capillaries.

III. The gill filaments have many folds to increase the respiratory surface.

IV. The direction of blood flow in gill filament is opposite of the direction of water flow.

• I and II

• III and IV

• II, III and IV

• All of the above

Multiple Choice

Which of the following structure is involved in breathing in a frog?

• Mouth cavity

• Diaphragm

• Intercoastal muscle

• Rib cage

Multiple Choice

Which of the following is the adaptation of skin of frogs for gaseous exchange?

• Moist and cold

• Slippery and slimy

• Thin and folded

• Moist and rich in blood capillaries

Multiple Choice

A man involved in a car accident. His rib is fractured and punctured his lungs. What will happen to the man?

• He will have dificulties in swallowing food

• He will experience short of breath

• He cannot sneeze

• He cannot speak

Multiple Choice

Which of the following enzyme is synthesized in stomach?

• Sucrase

• Pepsin

• Amylase

• Renin

Multiple Choice

Which of the following enzyme is synthesized in pancrease?

• Sucrase

• Pepsin

• Amylase

​

​

Multiple Choice

What will happen to the product of deamination process?

• Stored in cells

• Exreted out by kidney

• Act as main component of enzyme

• Return back to small intestine

DEAMINATION

• ​Deamination is the removal of an amino group from a molecule.

• ​Ammonia is toxic to the human system and enzymes convert it to urea or uric acid by addition of carbon dioxide molecules (which is not considered a deamination process) in the urea cycle, which also takes place in the liver.

• ​​Urea is produced during deamination and is eliminated as a waste product.

​

Multiple Choice

Which of the following is the function of fibre in food?

• Prevent disease

• Give colour to faeces

• Stimulate peristalsis

• Make food stay longer in intestine

Multiple Choice

• Thin, less muscular and less elastic

• Thick, muscular and elastic

• Thin, muscular and less elastic

I. sodium ion

II. vitamin K

III. potassium

IV. calcium ion

• I and II

• II and IV

• I and IV

• II and III

Multiple Choice
