Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States?

increase in dissolved oxygen levels

How would overexposure to X-rays affect most animal cells?

It would change the sequence of DNA nucleotides in affected cells.

It would increase cell specialization in organs.

It would produce new nucleotides for DNA molecules.

It would cause an increase in red blood cell production.

How are sexual reproduction and asexual reproduction different?

Asexual reproduction produces offspring identical to the parents, but sexual reproduction produces offspring with traits from both parents.

Sexual reproduction produces offspring identical to the parents, but asexual reproduction produces offspring with traits from both parents.

Sexual reproduction only occurs in multicellular organisms, but asexual reproduction only occurs in unicellular organisms.

Asexual reproduction only occurs in multicellular organisms, but sexual reproduction only occurs in unicellular organisms.

Which characteristic is present in offspring produced by sexual reproduction, but is missing in offspring produced by asexual reproduction?

an independent assortment of parent chromosomes

an identical copy of parent chromosomes

twice the number of parent chromosomes

only half the number of parent chromosomes

Which factor most affects the order of amino acids in a protein?

the DNA located in the nucleus of the cell

the cell in which the protein is located

the amount of ATP available for the cell’s use

the area in a cell where proteins are produced

Which statement best compares aerobic and anaerobic respiration?

Less ATP is generated during anaerobic respiration than during aerobic respiration.

More water is generated during anaerobic respiration than during aerobic respiration.

More oxygen is generated during anaerobic respiration than during aerobic respiration.

Less lactic acid is generated during anaerobic respiration than during aerobic respiration.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?

ATP is being rapidly consumed near the cellular membrane.

Substances are moving rapidly across the cell membrane.

Substances are moving from high to low concentrations.

Substances are moving through channels in the cell membrane.

Which option correctly describes the vascular tissue of plants?

Xylem carries water and dissolved minerals up from the roots and is made of non-living tissue

Phloem carries water and is living tissue

Xylem carries water and dissolved minerals up from the roots and is living tissue

Phloem carried food produced in the leaves and is made of dead cells

The stamen is the male part of the flower and includes the anther where pollen is produced.

The stamen is the male part of the flower and and contains ovaries

The pistil is the male part of the flower and contains the pollen

The pistil is the female part of the flower and produces sperm cells.
