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.

Cycle energy and matter to support the biosphere as a closed energy system

Explanation:  

The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.

Also, energy can enter and leave. The energy mostly referenced here is the sun.

Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.

For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils.  The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.

So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.

Cheers

Energy conservation in thioesters, acetyl-CoA and succinyl-CoA:
enot [183]

Answer:

B. ensure the production of GTP in the case of succinyl-CoA

Explanation:

Succinyl CoA like acetyl-CoA has a thioester bond with very negative free energy of hydrolysis. In this reaction, hydrolysis of the thioester bond leads to the formation of phosphoester bond with inorganic phosphate. This phosphate is transferred to histidine residue of the enzyme and this high energy unstable phosphate is finall transferred to GDP resulting in generation of GTP.

Hence the answer is B. ensure the production of GTP in the case of succinyl-CoA.
