Answer:
Chemical. quimico
Explanation:
Hope this helps. Chemical, because it's being exposed, no one is exposing it.
Espero que esto ayude. Quimico, porque esta expuesto, nadie lo esta exponiendo.
se un poco de espanol
buena suerte
Answer:
While doing medical research on the human subject, following limitations are unavoidable:
a). Privacy: The privacy of the subject involved in the research should be maintained.
b). the subject must be allowed to the minimal exposure to risks and it must be tested on animals first to avoid deaths.
c). The risk associated with the physiological and physical well being of the subject must be considered.
d). The subject must be well instructed about all the risk and procedure involved in the research.

Answer: B. The population using long sticks has mostly long sticks in its environment
Explanation:
Going back to the statement that reiterates the hypothesis after observations about the apes in the Introduction.
Reviewing the findings in this case, on the behavior of using sticks to dig seem to be the focus the experiment and choice length of the stick.
Making a judgment about whether or not the two finding has been supported is next step.
If there are equal numbers of short and long sticks in the environment of each population and the apes chooses one specific we can say their behavior is learned.
If the chimpanzees using short sticks have made the the sticks short by breaking long sticks then we can say this behavior is learned.
When the Young chimpanzees in both populations start out using sticks of many different sizes we can see that these variables of learning is yet to be perfected.
When individuals in the population that don’t use the common stick length for that population catch fewer termites this reveals a randomness in the behavior of interest.
At this point we can say that if the population using long sticks has mostly long sticks in its environment then there is a biased objective in the study and this does not support the hypothesis that the choice of stick length is a learned behavior.
Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.
