Answer:
Humoral immunity protects the body against extracellular pathogens and their toxins. Cell-mediated immunity protects the body against intracellular pathogens. Recognises pathogens in circulating in blood or lymph.
celluler immunity is very specific compared with humoral
Answer: Homeostasis
Our body temperature stays constant no matter the changes that may occur in the outer environment - for example, a hot summer afternoon or a cold winter morning. This is an example of homeostasis
Explanation:
Homeostasis is the maintenance of a stable internal environment. Hence, the body maintains a stable temperature, ph level, water-salt balance etc, necessary for healthy development based on the effects of the hormonal and nervous systems.
Answer:
The sickle-cell allele is widely known as a variant that causes red blood cells to be deformed into a sickle shape when deoxygenated in AS heterozygotes, in which A indicates the non-mutant form of the β-globin gene, and also provides resistance to malaria in AS heterozygotes.

Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
Eat foods that are high in fiber. Fiber helps stimulates the muscles in your small intestine that help you digest food better. Probiotic foods like yogurt as well as fresh fruits and vegetables also help carry beneficial bacteria to your small intestine to help prevent the accumulation and growth of harmful bacteria.
