What will happen to us if our body temperature fluctuate

If the body temperature is too low, the enzymes in the body become inactive so many metabolic reactions cannot happen effectively, our metabolic rate will be affected, we may suffer from hypothermia.

If the temperature is higher than 37degree celsius, we will have a fever. But this actually allows enzymes to work at their optimum temperature, which speeds up the metabolic reactions in the body and is good for us.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
