Question 1

Which of the following is true about cell division and cell cycle?

Accepted Answer

Cell cycle is a combination of interphase and mitotic phase where interphase is preparation stage before another cell division happens.

Answer

Mitosis produces sex cells while meiosis produces body or somatic cells.

Answer

Meiosis is a type of cell division that has only one round and results to daughter cells that are clone of the parent cell.

Answer

Mitosis is a type of cell division that has two rounds and results to daughter cells that are haploid.

Question 2

Which of the following is true about cell division?

Accepted Answer

None of the above

Answer

Meiosis is for production of cell for growth,

Answer

Mitosis is for production of sperm and egg.

Answer

Meiosis is for production of cell for maintenance and asexual reproduction.

Question 3

Which of the following may result from errors in cell division and cell cycle?

Accepted Answer

All of the above

Answer

When non-disjunction of chromosomes happen during anaphase, some cells may get less chromosomes and, thus, abnormality.

Answer

When cells do not stop from dividing and never reach specialization to have function, there can be the occurrence of cancer.

Answer

When non-disjunction of chromosomes happen during anaphase, some cells may get more chromosomes and, thus, abnormality.

Question 4

How do passive transport and active transfer compare and contrast with one another?

Accepted Answer

Both transports involve transfer of small particles across cell membrane.

Answer

Passive transport uses no energy because particles move from area of low to high concentration.

Answer

Active transport uses energy because particles move from area of high to low concentration.

Answer

All of the above

Question 5

When does membrane transport uses facilitators or membrane proteins?

Accepted Answer

When small particles have charges

Answer

When particles need to exit in bulk

Answer

When small particles are uncharged

Answer

When particles need to enter in bulk

Question 6

Why is membrane transport important?

Accepted Answer

All of the above

Answer

Materials need to exit the cell for secretion where important materials can be used outside.

Answer

Materials need to enter the cell for nutrition.

Answer

Materials need to exit the cell for excretion where useless materials must be removed.

Question 7

Which type of external environmental solution is best for cells?

Accepted Answer

Both

Answer

For animal cells and other non-walled cells, isotonic solution is the best so that osmolysis and shrinking of cells may be avoided.

Answer

Neither

Answer

For plant cells and other walled cells, hypotonic solution is the best so that more water can enter and make the cell rigid.

Question 8

Which of the following is true for enzymes?

Accepted Answer

None of the above

Answer

Lock and key model of enzymatic activity states that shape of the active site can be modified to make substrate fit.

Answer

Enzymes have active sites where inhibitors must attach to speed up chemical reactions.

Answer

Enzymes are proteins that can speed up chemical reactions by further increasing the demand for activation energy.

Question 9

Which is correct about ATP-ADP Cycle?

Accepted Answer

Both

Answer

When the third phosphate of ATP detaches from the rest, high amount of usable energy will be released for different cell activities.

Answer

Neither

Answer

ATP can be produced by combining ADP and inorganic phosphate.

Question 10

Which is true about photosynthesis?

Accepted Answer

Plants are green because it is the color of the light that they do not absorb.

Answer

Plants is the only group of photosynthetic organisms.

Answer

There is no photosynthesis during darkness.

Answer

High temperature and low carbon dioxide levels is good for photosynthesis.

Question 11

Which is true about photosynthesis?

Accepted Answer

Light reaction produces ATP and NADPH

Answer

H2O and CO2 combine during photosynthesis

Answer

CO2 is being released during dark reaction

Answer

H2O is being split during dark reaction

Question 12

Which is true about cellular respiration

Accepted Answer

It breaks down glucose to extract energy in the form of ATP

Answer

In presence of oxygen, fermentation will happen

Answer

Bacteria has the complete stages of cellular respiration

Answer

Its first stage is called electron transport chain

Question 13

Which is true about photosynthesis and cellular respiration?

Accepted Answer

Both

Answer

Cellular respiration happens in cytosol (first stage) and mitochondria (other stages)

Answer

Neither

Answer

Photosynthesis happens in chloroplast of plants

Question 14

Which is true about adaptation of photosynthesis of plants with high temperature?

Accepted Answer

All of the above

Answer

C3 plants cannot tolerate high temperature

Answer

C4 plants spatially adapt

Answer

CAM plants temporally adapt

Question 15

Which of the following will more likely be produced from fermentation using yeasts?

Accepted Answer

alcohol

Answer

acids

Answer

acetone

Answer

salts
