In comparing the number of differences in amino acids for cytochrome c: between a moth and a rattlesnake there are 31 different amino acids in the sequence, between a moth and a dog there are only 25, and there are 6 differences between a dog and a horse. Therefore, ( ) this is sufficient evidence to prove the moth is closer related to the dog than to the horse. ( ) dogs had to evolve earlier than horses, since moths are more primitive. ( ) evolution used to be considered a unifying theory until biochemical data showed only differences. ( ) added to anatomical similarities and fossil records, this provides additional evidence for constructing a phylogeny or family tree. ( ) biochemical information is not relevant to the evolution of organisms.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

but there is no

i guess you forgot putting it.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

explanation:

no u
