This causes a net force on the object acting upwards. ... So, for objects that weigh less, per unit of volume than water, the buoyancy force will cause the object to float. For objects that weigh more, per unit of volume (i.e: are more dense) the buoyancy force can't quite win out and the object will sink.
Answer:
Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability to lose electrons (oxidize), form basic hydroxides, form ionic compounds with non-metals.
Explanation:
Polyallelism.
Poly means many. So, when there are more than two alleles for the same gene locus we call it of polyallelism. This makes genetic variability much bigger because there are several alleles for a possible location in a chromosome and this would make, for example, from two parents a possible combination of two out of four possible alleles if between them they had all different alleles.
Answer:The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
