3)Which statement correctly describes the genetic makeup of the sperm cells produced by a human male?
1.Each cell has pairs of chromosomes and the cells are usually genetically identical.
2.Each cell has pairs of chromosomes and the cells are usually genetically different.
3.Each cell has half the normal number of chromosomes and the cells are usually genetically identical.
4.Each cell has half the normal number of chromosomes and the cells are usually genetically different.
2)Removal of one ovary from a human female would most likely
1.affect the production of eggs
2.make fertilization impossible
3.make carrying a fetus impossible
4.decrease her ability to provide essential nutrients to an embryo
38)Which statement best describes a controlled experiment?
1.It eliminates the need for dependent variables.
2.It shows the effect of a dependent variable on an independent variable.
3.It avoids the use of variables.
4.It tests the effect of a single independent variable.
28)Which organelle is correctly paired with its specific function?
1.cell membrane—storage of hereditary information
2.chloroplast—transport of materials
3.ribosome—synthesis of proteins
