Many organisms have unusual behaviors or characteristics when compared to similar organisms. For example, spiders are known for being almost completely carnivorous. They’ve evolved to have fangs and venom to help them catch and paralyze prey. However, scientists have recently discovered one unusual species of spider that eats an almost completely vegetarian diet.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
