Question
Explanation:
Identification of problem is the first scientific method. This is overtaken by asking questions
Answer: The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For a neutral atom:
Atomic number = Number of electrons = Number of protons
Given : Number of electrons = Number of protons = 6
Thus atomic number = 6
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Given: Number of neutrons = 6
Thus mass number = Number of protons + Number of neutrons = 6+ 6= 12.
The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.
<h2>
Question</h2>
I think the actual question should say "What is true of most body cells except skin cells?" I found this on another source.
Answer:
B
Explanation:
A is false for all cell types. In every cell, genes are organised into chromosomes in the same way. However, the way they are expressed is different between different cells.
C - is false for all cell types - all cells contain the same chromosomes with the same genes.
D - is false. All cells contain the same chromosomes and genes, it is the expression patterns of the genes that direct cell identity.
B is true, each body cell contains the same genes and chromosomes. The only exception is the sex chromosomes, which are haploid and genetically unique. This means that when fertilisation occurs following sexual reproduction, the diploid state is restored and a genetically unique organism is created.
Answer:
5.3⋅10 - 23 g
(-23 has to be small numbers above)
I think that is a chemical formula
