PilotLPTM [1.2K]

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.

Mike works in the metals industry. Which type of coal should he use as a fuel source?
Sonbull [250]

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.
