Answer: Option A and C.
Transport and receptor protein.
Explanation:
Membrane protein are pathway protein that control the flow of materials and information across the cell.
These proteins modify the cell response to the environment. Examples of membrane proteins are receptor and transport protein.
Receptor are protein that receive signal in the cell.
Transport protein are responsible for movement of ions,molecules or materials across the cell and its environment. These two proteins are responsible for modifying cell response to it's environment.
Answer:
Only options A (first one) reflects the instances with valid experiment or conclusion.
Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.
Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).
Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.
Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.
Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.
