Answer:
Species could go extinct when their environment changed if they could not adapt to the change.
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:
Genes
Explanation:
A gene is a hereditary unit that parents pass to their offspring, and they will determine the kind of characteristics the baby will have like will they be short or tall, have blue or brown eyes, will they have blond or black hair. The offspring will get different genes from its parents and it will therefore be genetically unique. Some traits or characteristics may be dominant over others. For example the mother has brown eyes and the father has blue eyes, so in this case eye color has two alleles (an allele is a specific version of a gene, in this case allele for blue eye color and an allele for brown eye color), and now the baby is born with brown eyes, so brown eye color was dominant over the blue eye color so that is the trait that we will see in the baby. The genetic is a lot more complex but this is a more simplified explanation of how offspring express certain traits from their parents.
