Frederick Griffith's discovery on the theory of genetics is credited to his experiment on mice. He subjected them to different strains of pneumonia bacteria. He concluded that there is an unidentified force that leads to the formation of different strains from what the mice were subjected to. This leads to the discovery of DNA, the carrier of traits. Scientist before did not know how the trait is passed on not until Griffith's experiment.

Some of the question I will ask about the lionfish include;
(i) What is the growth rate of lionfish number?
(ii) What range of salinities that lionfish can tolerate?
(iii) How do fish affect the first productivity of the coral reef?
(iv) How are lionfish affecting other species in the coral reef?
(v) How will the climate-ocean acidification and climate changen can affect the behaviour of lionfish?
Answer:
The correct answer is: A. active transport requires energy.
Explanation:
- Active transport can be defined as the physiological process by which molecules are enforced to migrate from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This occurs by the expenditure of energy. This type of movement is usually carried out by the integral membrane transport proteins or carrier proteins those remain interspersed across the plasma membrane.
- Passive transport can be defined as the physiological process in which no energy expenditure is required. This is because in this form of transport, molecules move from a region where their concentration is high to a region where their concentration is low, that is, down the gradient of their concentration, across a semi-permeable membrane. This type of movement can be mediated by simple diffusion or with the help of membrane transport proteins.
The paramecium does not have kidneys, live in a water environment, and regular water movement through contractile vacuoles.
