Which of these is not a way that large molecules, like glucose, can enter a cell? a. diffusion through the cell membrane. b. facilitated diffusion through protein channels in the cell membrane. c. endocytosis, when the cell engulfs the particles with pseudopods. d. active transport, when the cell pumps large molecules in through the membrane?

Diffusion

Explanation:

Diffusion can be defined as the movement of particles or substance which travels from a region of their higher concentration to an area where it has a low concentration.

It does not requires energy it is a passive process. It is used by smaller particles or gaseous particles.

It cannot be used for larger and heavier molecules like carbohydrates, fats and proteins as they are large and require energy for its transport.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
