A) true
b) false The atomic mass is never less than the atomic number.
c) this one is a bit tricky. For hydrogen, the atomic mass can equal the atomic number IF you are rounding the mass to the nearest whole number. That only works for hydrogen, though
d) false The larger the element, the more neutrons that are needed to keep the nucleus stable.
e) true
f) true
Vacuoles
➡️Plants have single large vacoule as compared to the animals which have many small vacuoles.✔️
➡️The main reason behind this fact are as follows:✔️
Storage:
➡️Plants form the base of the food chain.✔️
➡️They are capable of converting inorganic matter to organic matter.✔️
➡️To store these inorganic ions they are provided with the large vacuoles.✔️
➡️Moreover, plants can not move from one place to another.✔️
➡️So, it is very
easy for a plant to be able to store extra nutrients when they are around for use later when nutrients may not be available✔️
Growth:
➡️Plant cells grow by swelling.✔️
➡️They are provided with a rigid cell wall.✔️
➡️To make this wall expand, plant cells fill their vacuoles to exert pressure from inside.✔️

1 Oxygen atom.
Answer:
It solved the issue of depending on too many base units
Explanation:
It was first adopted by the French government. Metric system was developed by Gabriel Mouton of Lyons, he is called the founding father of the metric system. He proposed the decimal system of measurement that was refined by the scientists.
The metric system is simple for making measurements, you just need to know few metric units. There are seven base units in this system of measurement while there are twenty base units in inch-pound system of measurement. Metric system is easier to remember. The metric system follows the decimal number system and it decreases and increases in size by 10.
It has been adopted by all the countries of the world except Myanmar and US.
Answer:
127
Explanation:
Add the partial pressures up and then subtract the total from the added up thingy to get the pp of O2
