In driving a vehicle, the crash risk potential is approximately 4 times greater after dark than during the daylight hours according to the US Department of Transportation, Federal Highway Administration. This is due to the reduced visibility of the streets at night as well as direct bright light shining to drivers' eyes by the vehicles going the opposite way. This is also increased when there is heavy rain which further reduces the visibility.
Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
*Genetic determinism of sexes
*Two types are known.
I. Drosophila met at mammals , insects and some plants.
a) Chromosomes have notation:
Masculine ⇒ xy
Feminine⇒xx
II. Abraxas met at amphibians,reptiles,birds and fish.
a) Chromosomes have notation:
Masculine⇒xx
Feminine⇒xy
Generally, 10% of total available energy is transferred to the next trophic level in any food chain. Rest about 90 % of the stored chemical energy is lost as heat, a by-product of respiration. Let’s assume a 10% transfer rate, starting from producer (100%), primary consumer (10% ), secondary consumer 1%) and tertiary consumer have (0.1%). Therefore, quaternary consumers will have less than 0.1% of energy. Thus, statement is true.
Answer: So basically we have to know does the material's characteristics/compositions affect its density?
Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.
