The genotype of the offspring depends on the genotype of the parents which is missing from the question.
If the two parents have the genotypes BB and BB, the offspring will all have the genotype BB.
If the two parents have the genotypes Bb and Bb, the offspring will be 1 BB, 2 Bb and 1 bb.
If the two parents have the genotypes bb and bb, all the offspring will be of genotype bb.
If the two parents have the genotypes BB and bb, all the offspring will have the genotype Bb.
If the two parents have the genotype Bb and bb, the offspring will have the genotypes 1 Bb and 1 bb.
If the two parents have the genotype BB and Bb, the off spring will have the genotypes 1 BB and 1 Bb.
You can see that there are many situations depends on the genotype of the offspring. Therefore, the genotype of the offspring must be defined in the question.
The contractile units of skeletal muscles are myofibrils. Thus,option A is correct.
<h3>What is skeletal muscles?</h3>
Skeletal muscles are 32 to 40% of total body mass. The type of muscles that connect to bones and allow to perform a wide range of movements and functions.
Skeletal muscles are easily controlled and work according to the desire .
Skeletal muscles are specialized tissue that is connected to bones and allows movement.
Therefore, the contractile units of skeletal muscles are myofibrils. Thus option 1st is correct.

The correct structure is shown below,
According to rules the longest carbon chain is selected, and numbering is started from side nearer to carbonyl group. As the parent name goes to ketone, so among alkyne and halogen second priority is given to alkyne and 3rd to halogen
So, the name shoul carry following words,
3- one (for ketone)
5-yne (for Alkyne)
7-Bromo (for Halogen)
Result: So the structure is as follow,
<span>The correct answer to this question is the following:
The crust’s role in biogeochemical cycles allows it to provide the raw materials necessary for life on earth. The crust actually affects earth in a massive variety of ways, that are impossible for us to understand without the research undertaken by scientists to understand more about its' effects on life.</span>
