Active transport moves small molecules against the a concentration gradient which is the opposite of diffusion or that's what i found in Quizlet
Answer:
Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Explanation:
Rutherford concluded from his experiment that there are empty spaces present in most parts of the atom while a heavy positive charge is present in the nucleus of an atom due to which the tiny positively charged particles deflects because of positive-positive charge repulsion. Most of positively charged particles passes undeflected which indicated the presence of empty spaces in the atoms. The electrons revolve around the nucleus have no effect on the deflection of positively charged particles.
The right answer is A.
The term "hormonally active agent" (or endocrine disruptor) refers to any molecule or compound chemical agent, xenobiotic having hormono-mimetic properties and described as a cause of physiological abnormalities, and in particular reproductive abnormalities. Some examples are PCB, TCDD, DDT. Some of them were used as pesticides and are now banned for use. Their traces always exist at the soil level due to their persistence.
These agents are most often associated with breast cancer.
