Biology 10.1

Multiple Choice

As a cell becomes larger

• it is less efficient at moving waste materials across the cell membrane

• it does not need molecules for cell growth

• it is more efficient at moving nutrients across the cell membrane

• it places fewer demands on its DNA

Multiple Choice

Information "overload" is caused by

• a decrease in cell size & DNA

• an increase in cell size & DNA

• an increase in cell size & no increase in DNA

• a decrease in cell size & no increase in DNA

Multiple Choice

As a cell's size increases, what happens to the ratio of its surface area to its volume?

• the surface area increases as the volume increases

• the ratio stays the same

• the surface area does not increase as fast as the volume increases

• the ratio of surface area to volume does not matter

Multiple Choice

Which statement about sexual and asexual reproduction is true?

• there is no difference in the level of genetic variation produced by the 2 types of reproduction

• only yeast & bacteria reproduce asexually

• there is a lot of genetic vatriation in organisms that reproduce only asexually

• there is more genetic variations in organisms that reproduce sexually than those that reproduce asexualy

Multiple Choice

What is an advantage of asexual reproduction that is not an advantage of sexual reproduction?

• asexual reproduction produces a great deal of genetic diversity

• populations of asexual organisms produce viable offspring

• populations of asexual organisms can increase in number very quickly

• asexual organisms can evolve new genetic defenses against diseases
