  2. BAbout 5000 units
  3. CAbout 10 units
  4. DAbout 10 000 units
5.ふつう

Why must human gametes be haploid?

  1. ASo that the zygote has the normal number of 46 chromosomes
  2. BSo that the zygote has twice the normal number of chromosomes
  3. CSo that the gametes can divide quickly by mitosis
  4. DSo that the gametes can make more proteins
6.ふつう

When most people in a community are vaccinated, people who cannot be vaccinated are also protected. Why?

  1. AThe pathogen mutates into a harmless form
  2. BVaccinated people make antibodies for others
  3. CThe vaccine spreads from person to person
  4. DThe pathogen has too few hosts to spread easily
7.むずかしい

Why is one new DNA strand made in short pieces (Okazaki fragments) during replication?

  1. AHelicase cuts that strand into pieces before copying
  2. BThe lagging strand is made of RNA instead of DNA, so it must be built in pieces
  3. CDNA polymerase works only 5' to 3', and the strands are antiparallel
  4. DOnly half of the DNA needs to be copied
8.むずかしい

A green plant is kept in a sealed jar in complete darkness for a day. What happens to the carbon dioxide level in the jar?

  1. AIt stays the same, because plants do not respire
  2. BIt falls, because plants take in more CO₂ when they respire in the dark
  3. CIt rises, because the plant respires but cannot photosynthesise
  4. DIt falls, because the plant keeps photosynthesising
