Answer:
The cells circulate in the atmosphere, then joining together, and eventually, they clusters, (clouds) get too heavy, and rain falls.
Explanation:
Atomic number of an atom equals to the number of nucleus in the nucleus of the atom. Therefore, the answer is 74.
The proton of an element is never changed. No matter if it's an atom or ion. It's like an ID number for an element. It defines the type of element. Don't mix up atomic number with mass number though, mass number is the total sum of of the number of protons and neutrons in an atom.
Theres one more subatomic particle in an atom, that is electrons. But since they're too light, they won't be counted in mass. Also, the number of electrons in an atom equals to the number of proton, also the atomic number. If the number of electrons is different, it's no longer an atom, but an ion.
Answer:
Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
D is false it would put less oxygen into the air
Answer:
volume
surface area
Explanation:
The growth of the cell includes the increase in the mass of the cell by the absorption of nutrients and elimination of the wastes. This process helps the cell to grow in size. In this process, the volume of the cell increases faster than the surface area. This gradually leads to the decrease in the surface area of the cell. The increase in the volume expands the cell membrane also.
