What does homozygous mean?

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

What is cytokinesis?

  1. AThe division of the cytoplasm into two cells
  2. BThe pairing of homologous chromosomes
  3. CThe copying of DNA before division
  4. DThe condensing of chromosomes in prophase
3.Easy

What is an organism's genotype?

  1. AThe traits that can be seen or measured
  2. BThe environment in which it lives
  3. CThe number of cells in its body
  4. DThe alleles it carries for a trait
4.Medium

A protein is made to be secreted out of the cell. What path does it follow?

  1. ARough ER, then Golgi apparatus, then vesicle, then cell membrane
  2. BGolgi apparatus, then rough ER, then nucleus, then cell membrane
  3. CSmooth ER, then mitochondrion, then vesicle, then cell membrane
  4. DNucleus, then lysosome, then Golgi apparatus, then cell membrane
5.Medium

Why are stains such as iodine or methylene blue added to cells on a microscope slide?

  1. ATo make the cells divide
  2. BTo make structures easier to see
  3. CTo keep the cells alive for longer
  4. DTo make the cells larger
6.Medium

Why can small nonpolar molecules cross the cell membrane easily while ions cannot?

  1. AIons are larger than most membrane proteins
  2. BThe membrane is made mostly of long carbohydrate chains
  3. CThe membrane carries a strong positive charge
  4. DThe bilayer's core is made of hydrophobic tails
7.Hard

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. AChanges acquired in a lifetime are not passed on in the 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. DNeck length is not affected by any genes
8.Hard

Some chemotherapy drugs stop spindle fibres from forming. Why do they often cause hair loss and damage to the gut lining?

  1. AThese cells divide by meiosis instead of mitosis
  2. BThese tissues also contain rapidly dividing cells
  3. CThese tissues are made only of haploid cells
  4. DThese cells have no mitochondria
