Answer:
The correct answer is - 2.107 x 10^24 mango seeds.
Explanation:
Given:-
number of moles of mango seeds = 3.50 mol
Solution:-
1 mol of mango seeds = 6.02 x 10^23 mango seeds
6.02 x 10^23 is Avagadro numbers
1 mole is the number of particles contained in a substance
. The number of moles can also be calculated by dividing the mass by the molar mass of the element or molecule of the substance with the Avogadro's number.
Therefore,
3.50 mol of mango seeds = 3.50 x 6.02 x 10^23 mango seeds
3.50 mol of mango seeds = 21.07 x 10^23 mango seeds
3.50 mol of mango seeds = 2.107 x 10^24 mango seeds
Answer: (D)
Explanation: biotic factors depend among abiotic factors, meaning that living things need non-living things in order to survive. That also means that biotic factors everywhere including the surrounding area need to be thought of in this sense so that they are able to survive in the environment they are in.

is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>
Answer:
Hydrogen disulfide
Explanation:
Hydrogen disulfide
, which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.
It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.
Answer:
Something that can be tested, or rationalized.
Explanation:
You didn't give any statements to choose from, so I'll give you a rule of thumb. When finding a scientific statement, make sure it's something like "The tide is higher at noon than it was at 3 am." and not "Your dog is itchy, so that means a bad storm will arrive."
