In the periodic table, the atomic radius of the atoms decrease from left to right. This means that Carbon is smaller than Boron. So from the choices you can rule out the first and third choice. 

Now, the reason why Carbon is smaller than Boron is because Boron has more protons and as the protons increase it attracts the electrons closer, which makes the atom smaller. 

Carbon has more protons, so it exerts a greater pull. The answer is then Option 2: Boron has a larger radius and the protons in carbon exert a greater pull. 

As for the second question, a compound is defined as a substance that is made up of two DIFFERENT elements that are chemically bonded. If you look at the second option, it is a compound. It is made up of hydrogen and oxygen atoms.

The answer is then option 2.

The smallest contractile unit within skeletal muscle would correspond to the distance between which two points in the figure?
Tpy6a [65]

The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.

<h3>What is the smallest contractile unit within skeletal muscle?</h3>

A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.

In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

Why are spores, as opposed to sperm, the primary means of dispersal in moss?.
FromTheMoon [43]

spores are light & small & encapsulated

The spores are very resistant to the the external environment since they are encapsulated structures , this type of dispersal helps past against natural calamities and promotes more living of the plant in further generations in extreme conditions . Since they are light weight and have small size they can be dispersed easily so helps in diversification of the plant in the area . These advantages are not well suited for sperms. Moreover, in mosses, the sperm requires water for the movement to meet the ova cells to make zygote.
