An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.

A student used poster board to construct this model of DNA.Which statement describes this model of DNA?
pantera1 [17]

Answer:

The model is inaccurate because the base pairs are incorrect.

Explanation:

The model of DNA that the student made was:

G-G

A-A

T-T

C-C

G-G

A-A

T-T

C-C

The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.

The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.
