Carbon, helium, and sodium are monoatomic elements.
Hydrogen, iodine, and oxygen are diatomic elements.
The atomic number of an element never changes no matter how many neutrons they have so Sulfur would just have an atomic number of 16 like normal.
The question is incomplete, the complete question is;
Which of the following aspects of biotechnology is Not considered to be a moral or ethical issue?
a.research and testing on animals
b.cloning living material
c.reducing research cost
d.damaging the environment
Answer:
c.reducing research cost
Explanation:
Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.
Research and testing on animals is contested as an ethical issue by animal rights activists.
Cloning living material is prohibited among some sections of society and is also being contested as an ethical issue.
Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.
However, reducing research cost is highly acceptable in any research. It does not pose an ethical issue.
This is a fill in the blanks question.
This is where the blanks are: A __________ is scientific knowledge established through direct observation and remains constant. Scientific knowledge can change when scientists _____________
The answer is followiing.
Answer: A <em>law</em> is scientific knowledge established through direct observation and remains constant. Scientific knowledge can change when scientists <em>find new evidence</em>.
Explanation:
A scientific law describes the relation (usually in mathematical terms) of natural phenomena and is supported by numerous observations and experiments. The laws are established when all the observations and result show that all the facts obey the same relation. For instance, the Universal law of gravitation: all the objects are attracted with a force that is directly proportional to the product of their masses and inversely related to the square of the distance that separates them: in lay terms, everything that goes up has to go down, and you do not expect that when a parachutist jumps out of an airplane he or she does not fall on the ground.
On the other hand, a scientific theory, although is an explanation that has been repeatedly tested and verified, is always under scientific scrtutiny and, as additional evidence is gathered it can be modified or replaced by a new theory. That is why it is said that scientific theories have to be testable and falsiable: if it is not testable and falsiable then it is not a scientific theory.
Scientific theories are aimed to describe, explain and make predictions about the objectivable world.
