The answer is fertilization.
Fertilization is the process in which two haploid gametes fuse to create one diploid cell. <span>In this process, male sperm fuses with female egg which creates a zygote. Since they are haploid (n), after fertilization, they will create the zygote which contains chromosomes from the sperm and chromosomes from the egg. The zygote, thus, has two sets of chromosomes, so it is diploid (2n).</span>
Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin. Acetylcholine, gastrin, and histamine stimulate the proton pump in parietal cells to release hydrogen ions and decrease pH.
The answer is 25%. The
other 75% will have dominant phenotype. However,
in the dominant phenotype, 25% have a homozygous dominant genotype, while the remaining
50% have a heterozygous genotype. Find attached a punnet square that will
clearly illustrate this;
Answer:
Lots of bacteria are present as the microflora of a baby's gut which helps it to extract the nutrition from mother's milk and also helps the baby to maintain a low number of pathogenic bacteria in its gut.
Some bacteria present in the baby gut release enzymes like glycoside hydrolase which helps baby to digest carbohydrate present in the mother's milk.
Bacteria like Bifidobacterium, Streptococcus, Staphylococcus are already present in breast milk which helps in making gut microflora of baby and this gut microflora helps in extracting nutrients from mother's milk.
