Answer:
Retinoblastoma is more common in people due to the mutation of RB gene in them.
Explanation:
Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.
When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.
I believe the main purpose of wildlife (movement) corridors is to connect two otherwise isolated populations. Wildlife corridors are links of wildlife habitat that joins tow or more larger areas of similar wildlife habitat. They are very critical for the maintenance of ecological processes such as allowing the movement of animals and the continuation of viable populations.
The sperm are changing chemical energy into kinetic energy.
Chemical energy is defined as the chemical substance’s potential to undergo a transformation through a chemical reaction. So, this type of energy can be transformed to other forms of energy by a chemical reaction.
Kinetic energy, on the other hand, is the energy that an object (structure) possesses due to its motion.
So, in the example above, chemical energy of the glucose is used (by breaking the bonds of this molecule through the chemical reaction) for the formation of sperm’s kinetic energy (necessary for movement).
