Answer:
the answer is opetuon B
released the drugs into the cancer cells?
a) Graphite and diamond because these well known substances have been used
for years to treat cancer
b) Graphite because it is found in pencils and is a good lubricant
c) Fullerene and carbon nanotubes because they have empty spaces inside the
molecules
d) Diamond because it is one of the hardest substances
Answer:
c) Fullerene and carbon nanotubes because they have empty spaces inside the molecules
Explanation:
Fullerene and carbon nanotubes would be the most desired in order to hold the cancer fighting drugs and to carry them through the body safely.
Answer:
balanced............
B He estimated the number of electrons in atoms of each element.
C He arranged the elements by different properties to find a pattern.
D He organized the elements by their atomic number.
Mendeleeve's periodic table was based on the atomic mass of each element.
The correct answer is option A: He determined the mass of atoms of each element.
The periodic table can be described as a regular arrangement of elements based on some periodic properties. The periodic table has evolved through the ages. Its patter has been changed several times before it arrived at its present form.
The Mendeleev periodic table was based on the mass of atoms of the elements. This table was published in Russia in 1869. His table even predicted elements that were yet to be discovered.

Answer: weight helps gravity
Explanation
for example, when you outside with the wind blowing, your weight dont let you get carried away.
Technologies helping humans cope with gravity include methods to simulate weightlessness for training and entertainment, and prospective technologies suggested by general relativity theories like the gravity-based time machine. Studies on the gravity response in plants can also help sustain long-term space missions.
There are many technologies and methods designed to help humans cope with the effects of gravity. For example, astronauts on the International Space Station (ISS) experience gravity but appear weightless because they are in constant free fall around the Earth. This is akin to the principle of equivalence, which states that falling around the Earth creates the same effects as being far off in space, away from all gravitational influences.
Training facilities, like NASA's Vomit Comet, provide an environment for astronauts to experience a state of near-weightlessness or free fall, preparing them for their missions in space. Moreover, innovations such as underwater filming, wire stunts, and computer graphics can also mimic the appearance of weightlessness, as seen in movies such as Gravity and The Martian.
Also, findings related to gravity and time machines in general relativity suggest that it might be possible, in theory, to move through time using gravity. Meanwhile, studies on how plants respond to gravity might contribute to long-duration space missions by regenerating the atmosphere, purifying water, and producing food.
