Answer:
Centripetal force is perpendicular to the velocity of the satellite.
Explanation:
because there is no friction or wind resistance, the speed of the satellite remains the same
Answer:
<h3>Yes, Passive transport can occur in dead cells.</h3>
Explanation:
For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.
A concentration gradient is the difference in the concentration of solute molecules across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.
The transport of the solvent can occur as well, from higher concentration to lower concentration.
Answer:
The correct answer will be option- B.
Explanation:
The Transduction is the process of the genetic transfer by which the foreign DNA is incorporated in the genome of the cell using virus or bacteriophage. The process of transduction was discovered by the Zinder and Lederberg in 1952 in the species of<em> Salmonella</em> bacteria. The transduction process is of two types: generalized and specialized transduction.
Thus, option- B is the correct answer.
