Answer;
Atomic number Tc = 43 , which is equivalent to the number of protons in nucleus.
Number neutrons = mass number - number of protons = 99 - 43 = 56 neutrons .
Number of electrons = number of protons - charge = 43 - (+7) = 36 electrons
Explanation;
-Atomic number is the number of proton in the nucleus of an atom of a given element. Mass number is the total number of protons and neutrons in the nucleus of an atom. A neutral atom has equal number of protons and neutrons.
-Isotopes are atoms of the same element with the same atomic number but different mass number.
Answer:
The moon
Explanation:
Most nocturnal plants, animals and insects, like moths, use the moon as their guide through the night. This is why insects are attracted to light in the nights
Mitosis is used to produce daughter cells that’s genetically identical to parent cells. And Mitosis affects change by the cell copying or “replicating” its chromosomes, and then splitting the copied chromosomes equally to make sure that each daughter cell has a full set.
Answer:
In order to change any part of the cell theory, we will have to prove that the cells are not the basic unit of life. We will have to provide evidence that a cell does not distinguish a living thing from a non-living thing. We will either have to prove the spontaneous generation to be true or have to prove that if not cells, then what are the basic units of life. We will also need evidence to prove that a cell does not arise from a pre-existing cell.
most likley true?
im not sure but imma go with true
