During aging, the reduction of HCL by the stomachA. causes constipationB. increases appetiteC. reduces the adsorption of vitamin B12D. increases the size of stomach

27. Lack of microbes on the sterile Martian surface mayA. weaken our immune systemB. amplify our immune systemC. have no effect on our immune system

42. Changes in heart muscle mass in Martian humans will increasethe likelihood ofA. hypertensionB. heart failureC. diabetesD. renal failure43. Getting to Mars could be accomplished using this method, inwhich one small vehicle would be utilized to descend to the surfaceof Mars and return up to Mars’ orbit, where it will rendezvous withanother spacecraftA. Mars Orbit RendezvousB. Earth-Mars RendezvousC. Space X47. Since the thymus gland atrophies as aging occurs,A. immunity increasesB. immunity decreasesC. there is no change to immunity


17) Decrease in Martian humans

Bone loss occurs in the weightless environment of space becausebones no longer have to support the body against gravity.

18) Increases the size of stomach

The mucus membrane of the stomach thins with age resulting inlower level of mucus, hydrochloric acid and digestive enzymes. Thisreduces the digestion of proteins and lead to chronic atrophicgastritis.

27) Weaken our immune system

Imbalances in the gut microbiota may disregulate immuneresponses and lead to the development of chronic inflammatory andautoimmune dysfunctions

31) positioning mirrors to reflect sunlight onto the planet.

This could be done by spreading dark dust from Mars moons,phobos and Deimos, which are among the blackest bodies in the solarsystem or by introducing dark extremophile microbial life form suchas lichens, algae and bacteria. The ground would then absorb moresunlosun, warming the atmosphere.

40) Increased susceptibility to illness

The brain and nervous system go through natural changes. Brainand spinal cord lose nerve cell and weight (atrophy).

42) Heart failure

Microgravity affects the hearts ability to pump blood andprovide oxygen to cells throughout the body, which can have serioushealth consequences, especially upon landing on a planet.

43) Mars orbit rendezvous

MOR is a space travel concept where two space craft meet up and/or dock in Mars orbit.

47) Immunity decreases

Thymic involution or thymic menopause is thought to be the causeof aging of the immune system where there is diminution of thethymic epithelium, decrease of T cell output and impaired cellmediated immunity.
