What does homozygous mean?

  1. AHaving two identical alleles for a gene
  2. BHaving two different alleles for a gene
  3. CHaving only one copy of a gene
  4. DHaving an extra chromosome
3.やさしい

What is a stem cell?

  1. AA fully specialised cell that can no longer divide or change its type
  2. BAn unspecialised cell that can divide and become other cell types
  3. CA plant cell found only in the stem
  4. DA cell that carries oxygen in the blood
4.ふつう

Why do plants wilt when the soil around their roots becomes very salty?

  1. ASalt makes the root cells swell and burst
  2. BSalt blocks sunlight from reaching the leaves
  3. CWater leaves the root cells by osmosis
  4. DThe roots take in too much water
5.ふつう

What happens during telophase of mitosis?

  1. AThe chromosomes line up across the middle of the cell
  2. BThe DNA is copied for the next division

A point mutation changes a codon in the middle of a gene into a stop codon. What is the most likely effect?

  1. AA protein that is longer than normal
  2. BA protein with one different amino acid
  3. CA shortened protein that usually does not work
  4. DNo change, because stop codons are ignored

An old idea says giraffes got long necks because each one stretched to reach leaves and passed the longer neck to its young. Why is this idea rejected?

  1. ANeck length is not affected by any genes
  2. BOnly plants can pass on traits to offspring
  3. CGiraffes do not eat leaves from tall trees, so stretching is not needed
  4. DChanges acquired in a lifetime are not passed on in the genes
