Correct Answer: pairing between complementary bases occurs
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: mitochondria
Correct Answer: A Phospholipid is a lipid molecule which has hydrophilic head and a hydrophobic tailand and is a main component in making of all cell membranes in which they two form a parallel layers called Phospholipid bilayer
Correct Answer: large part of the lobe or lung
Correct Answer: transcription
Correct Answer: Tetrad
Explanation:
Tetrad is a homologous chromosome pair in the given options. A homologous chromosome pair is a pair of chromosomes one from father and one from mother that has same gene sequence after the process of meiosis.
