Answer:
The presence of proton pumps in the lysosome membrane that allows the organelle to maintain higher concentrations of protons.
Explanation:
Lysosomes are known as a membrane-bound cell organelle that is present in many animal cells. They are spherical type vesicles in structure. Lysosomes contain hydrolytic enzymes these enzymes help in the break down of different kinds of biomolecules.
The lysosomal membrane helps to protect the cytosol, and rest of the cells, from the degradative enzymes which are present in the lysosome. They have the ability to maintains their pH by pumping in H+ ions (protons) from the cytosol across the membrane with the help of chloride ion channels and proton pumps.
Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.

B interest rates are not just the same as we do not like that we have a new account and a dollar on our own account so you don’t want it for the first one and then
