Answer:

<em>The correct option is C) crossing over and independent assortment</em>

Explanation:

Crossing over and independent assortment can be described as the two essential phenomena of meiosis which brings genetic variations. During crossing over, the exchange of DNA segments between homologous chromosomes takes place.

klasskru [66]

Answer:

the overlapping decreases between the thin and thick filaments.

Explanation:

When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.
