Answer:
(C) 10 times more acidic than distilled water.
Explanation:
The pH scale is logarithmic, meaning a pH difference of one is a difference of 10 times.
Answer: Option C.
C)the tails of plant lipids cannot pack as tightly together as animal ones
Explanation:
The tails of plant lipids cannot pack as tightly together as animal ones because the double bond in plant lipids make the hydrocarbon chains to bend making them no to pack tightly together which cause a reduction in van der Waals interaction between the fatty acids. The length of the double bond also affect the melting point of fatty acids . If the hydrocarbon chain is long, melting point will be high .
<u>Answer</u>:
1. Type of medium - the nutrient availability is one of the vital factors for the growth of a bacterial colony. Thus, the used growth medium will fulfill this requirement.
2. Incubation temperature - all bacteria have an optimal temperature range in which maximum growth is achieved. Any variations from this will result in negative effects on the amount of bacteria that are produced.
3. Moisture - bacteria thrive in moist or wet environments. Thus, the availability of moisture is another vital factor for the growth of the colony.
Gum should not affect a DNA test but if it did I would assume because of the bacteria/dna on the gum/gum wrapper.
When temperature inversion occurs, cold air underlies warmer air at higher altitudes. Temperature inversion may occur during the passage of a cold front or result from the invasion of sea air by a cooler onshore breeze.
