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.
Correct Answer: Iris
Explanation:
The size of the pupil is controlled by the Iris when light enters the eye.
Correct Answer: Testosterone
Explanation:
Testosterone is the hormone which is associated with aggression.
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: 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: a taxon composed of one or more species and a classification level lying below family
Explanation:
A genus can best be defined as a taxon composed of one or more species and a classification level lying below family.
