Due to the surface of the water, light insects are able to walk on the surface of water.
Surface tension also accounts for those with wide feet (generally webbed feet). They have more area on the underside of their feet and if they move fast enough (depending on their weight - the heavier they weigh, the faster they must go to keep on the surface of the water), they are able to "walk on water".
The T lymphocytes capable of killing invading cellular organisms such as bacteria, protists, or fungi are cytotoxic T cells also known as CD8+ cells. These cells are capable of recognizing whether a cell has a major histocompatibility complex I (MHC I) surface protein or not. Those with absent MHC I surface protein will be killed by the cytotoxic T cells. Those with the MHC I surface protein expressing an invading antigen will also be killed by cytotoxic T cells. Those with the MHC I surface protein without an antigen will be spared by the cytotoxic T cell.
Answer:
Alleles
Explanation:
In diploid organism, genes occur in pairs on chromosomes and such pairs are referred to as allelic pairs. An allele is an alternative form of the same gene that controls the development of a pair of contrasting genes. The genetic constitution of an organism is known as genotype while its phenotype refers to a set of observable characteristics of an organism which are an expression of an individual genotype.
