Answer:
Plasma membrane is the semi-permeable membrane that allow the movement of some selected particles only against the concentration gradient or along the concentration gradient.
Different substances can be move through the diffusion, active process and passive process. The hydrogen in the vesicle has been moved through the facilitated diffusion. In this process, the hydrogen ions will move along the concentration gradient without the requirement of energy but requires the channel protein for its transport.

Answer:
c. Ribosomes
Explanation:
Ribosomes can be found in eukaryotic and prokaryotic cells. In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm. In both cells, ribosomes intertwine into an RNA molecule and form polysomes.
Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
Binary fission is Asexual. It has a process where it involves splitting the DNA of a parent cell creating two daughter cells. Conjugation is a sexual reproduction. It involves the direct transfer of genetic material between two bacterial cells.
An allele is a variant of a gene. Each cell has two alleles (one per parent) for each gene: one dominant, one recessive. ... Locus is to some extent interchangeable with gene, though locus is less specific and doesn't imply that the location codes for an entire gene
