If there is an increase in orbital radius, this would also increase the average orbital speed or the velocity.
The orbital radius and the orbital speed is directly proportional. When the radius is increased, the orbital speed will also increase but it has to add energy to the system to increase the orbital radius.
D. The macronucleus does not disintegrate during conjugation.
The macronucleus contains the working copies of genes needed to support an enormous cell. It is formed by a division of the fused diploid nucleus after conjugation followed by multiple rounds of internal gene replication which does not occurs in the micronucleus.
Covalent bond is when two atoms share one or more pairs of electrons, an example of this could be H20 or C02.
ionic bonds are when one or more electrons from am atom are removed and attached to another, which can result in positive or negative ions which attract each other, an example of this could be table salt.
