Year 11 Week 4 Quiz - Meiosis And The Digestive System - Quiz

Questions and Answers

1.

A crossover in meiosis is an exchange of genetic material between:
- A.
  
  Sister chromatids of homologous chromosomes
- B.
  
  Non-sister chromatids of homologous chromosomes
- C.
  
  Sister chromatids of non-homologous chromosomes
- D.
  
  Non-sister chromatids of non-homologous chromosomes
2.

Random orientation of homologous chromosomes occurs in ________ of meiosis.
- A.
  
  Prophase I
- B.
  
  Metaphase I
- C.
  
  Prophase II
- D.
  
  Anaphase II
3.

Why do homologous chromosomes pair in prophase I and not in prophase II?
- A.
  
  Pairing of chromosomes requires precision and it would take too much metabolic energy to pair them twice.
- B.
  
  The kinetochores have been used up after separating the sister chromatids during meiosis I.
- C.
  
  The cells are haploid during prophase II and therefore can't pair.
- D.
  
  Meiosis I is more like mitosis than meiosis II is, and so the chromosomes pair up similarly in meiosis I and mitosis
4.

The number of chromosomes in daughter cells produced by meiosis is ________ the number of chromosomes in daughter cells produced by mitosis.
- A.
  
  Diploid
- B.
  
  Triploid
- C.
  
  Half
- D.
  
  Double
5.

At the end of meiosis I, each daughter cell is:
- A.
  
  Diploid, and each chromosome consists of a single chromatid.
- B.
  
  Haploid, and each chromosome consists of a single chromatid.
- C.
  
  Haploid, and each chromosome consists of a single chromatid.
- D.
  
  Haploid, and each chromosome consists of two chromatids.
6.

Which one of the following is absorbed in the gastrointestinal tract without being digested?
- A.
  
  Starch
- B.
  
  Proteins
- C.
  
  Triglycerides
- D.
  
  Vitamins
7.

If you suck on a plain piece of bread, it will begin to taste sweet after a few moments. Saliva contains the digestive enzyme ________________, which breaks down starch into ________________.
- A.
  
  Amylase; glucose
- B.
  
  Pepsin; maltose
- C.
  
  Amylase, maltose
- D.
  
  Maltase, glucose
8.

If you were able to collect the chyme from the small intestine and isolate its various enzymes, most of the enzymes would have been produced by the:
- A.
  
  Gall bladder
- B.
  
  Small intestine
- C.
  
  Pancreas
- D.
  
  Stomach
9.

Arrange these events in the order in which they occur during fat digestion, absorption, and transport:1. chylomicrons enter lacteals2. triglycerides, phospholipids and cholesterol coated with protein3. fatty acids and glycerol packaged into micelles4. bile salts emulsify fats5. lipase digests fat
- A.
  
  1,2,4,5,3
- B.
  
  4,5,3,2,1
- C.
  
  2,5,4,3,1
- D.
  
  5,3,4,1,2
10.

Which of the following parts of the digestive system would contain a fluid that lacks digestive enzymes?
- A.
  
  Stomach
- B.
  
  Duodenum
- C.
  
  Gall bladder
- D.
  
  Pancreas
