Correct Answer: Measures of the brain activity closely resemble waking consciousness, but the person is incapable of moving.
Explanation:
REM sleep i.e, Rapid Eye Movement sleep is also known as paradoxical sleep because the measures of the brain activity closely resemble waking consciousness, but the person is incapable of moving as the brain is in fully active mode that time.
Correct Answer: evolutionary relationship
Correct Answer: skin
Explanation:
Leprosy is the disease which effects skin.
Correct Answer: Spleen
Explanation:
Spleen is called as the graveyard of RBC Red Blood Cells where they are selectively destroyed/recycled by macrophages.
Correct Answer: TRUE
Explanation:
All enzymes are proteins but all proteins are not enzymes since, enzymes are subset of proteins.
Correct Answer: TRUE
Explanation:
True, Stress is a factor that contributes to heart disease risk.
More factors that contributes to heart disease risk are blood pressure, cholesterol, smoking, physical inactivity and overeating.
Correct Answer: AT
Explanation:
The nucleotides that are present in DNA molecule are 4. They are Thymine (T), Guanine (G), Adenine (A) and Cytosine (C).
Here in this Adenine pairs with Thymine (A - T) and Cytosine pairs with Guanine (C - G).
Correct Answer: Testosterone
Explanation:
Testosterone is the hormone which is associated with aggression.
Correct Answer: Iris
Explanation:
The size of the pupil is controlled by the Iris when light enters the eye.
Correct Answer: Prokaryotes
Explanation:
Membrane bound organelles are not found in the cells of Prokaryotes whereas Eukaryotes have nucleus and membrane bound organelles.
For example : Bacteria is prokaryotic organism with lack of nucleus and membrane bound organelles whereas fungi is a eukaryotic with nucleus and membrane bound organelles.
