Answer:
B. bituminous
Explanation:
Bituminous coal is an organic sedimentary rock produced by compression of peat bog material by diagenesis and submetamorphics.
Bituminous coal has low moisture and high carbon content and hence used for the production of steel and cement, coke production an electricity generation.
Coking coal is a type of Bituminous coal are best used as fuel dource in metal industry having very narrow range of volatility and plasticity. Volatility is maintained by smelters to optimize the ease of burn rate, ignition, and energy output of the coal as this determines the burn rate of the coal.
Hence, the correct option is B. bituminous.
Answer:
Fewer Offspring than the environment can support
Explanation:
It takes time for a creature to adapt to its Environment. So that puts off 2.
Your guaranteed to get traits from your parents so that rules out #1
There isn't really an equal probability of survival for an offspring, ruling out #3.
So that leaves us with 4. I'm not biology expert, I'm just letting you know how I did this problem. Just in case i'm wrong, I would double check with other answers :)
Abiotic Factors of Taiga Biome: The abiotic factors includes temperature, sunlight, soil, air, water. In taiga biome the climate is marked by bitterly cold winter of long duration and cool brief summer season. The winter months are always below freezing point.
Answer:
The three main steps of PCR amplification are :
Denaturation
Annealing
Elongation
Explanation:
Polymerase Chain Reaction (PCR) can best be describes as a procedure to amplify or make copies of DNA fragments.
The basic steps involved for PCR are :
1. Denaturation
In this step, the two complementary strands of DNA are seperated by the usage of heat. The best temperature for this procedure is 95°C.
2. Annealing
After denaturation, each strand of DNA serves as a template foe building a new strand. During the process of annealing, the temperature is reduced so that the primers can attach to the DNA strands. The optimum for this depends on the nature of the primers but usually the most feasible temperature is 55°C.
3. Elongation
In this step, the DNA polymerase adds nucleotides to the primers attached to the templates. The optimum temperature For DNA polymerase to work is 72°C.
