true

false

9. The most basic part of our brain is the part that controls our autonomic functions, referred to as the mammalian brain.

true

false

10. Aging reduces all of the following in the circulatory system except

A. white blood cells

B. hemoglobin

C. lymphocytes

11. Progeria and Werner syndrome, which both cause premature aging, are a result of

A. genetic causes

B. environmental factors

C. epigenetics

Answer 1

1. A. atmosphere

Placing a magnetic dipole field between Mars and the sun may help restore Mars' atmosphere because in its absence solar radiations go unchecked and cause Mars to lose its atmosphere.

2. B

Sporophytes generate spores and sporophyte is a multicellular stage in plant and algae in which it produces spores which facilitate gametogenesis via asexual mode.

3. B

During aging, there is a slight reduction in heart rate because fatty & fibrous tissues accumulate around the SA node

4. True

A key difficulty of preparing a computer system to house human brain information is trying to emulate the signaling pathways of the nervous system is true since these are numerous and very complex to emulate.

5. Osteoporosis

Loss of bone mass during aging leads to osteoporosis.

6.  E all of the above

Signs and symptoms of aging can be slowed by eating a healthy diet, exercising, caloric restriction, and socialization.

7. D. all of the above

In order for cross-species transmission to occur there must be contact between the virus and host, the infection needs to be amplified within the host, and variants need to be produced in the new host that allow for transfer to other humans.

8. True

The Fermi Paradox attempts to explain the likelihood of finding intelligent life in other galaxies.

9. False

The most basic part of our brain is the part that controls our autonomic functions, referred to as Hind Brain and it has cerebellum, reticular formation, and brain stem.

10. lymphocytes

Aging reduces all of the following in the circulatory system except lymphocytes

Lymphocytes diversity is decreased with ageing.

11. Epigenetics

Progeria and Werner syndrome, which both cause premature aging, are a result of epigenetics
