Prokaryotes:
1). lack a well-defines nucleus.
2). cannot perform basic life functions.
Prokaryotes have cell organelles like the Endoplasmic Reticulum and Chlorophyll and prokaryotes are smaller than a eukaryote.
Hope this helps :)
Answer:
Significant figures are a measure of <u><em>precision</em></u>.
Explanation:
The significant figures of a number are those that have a real meaning and, therefore, provide some information. Therefore, the set of digits that are known with certainty in a measure are called significant figures and are the digits of a number considered non-null.
Any experimental measurement is inaccurate and must be expressed with its significant figures.
In this way, significant figures express the precision of a measuring tool.
A diploid-dominant life cycle strategy in which the only haploid cells produced by the organism are the gametes. the embryo, specialized diploid cells are produced within the gonads (testes and ovaries). Germ cells are capable ofmitosis to perpetuate the cell line andmeiosis to produce gametes.
Answer:The number of atoms in 2.0 mole Al is A. 2.0 Al atoms. B. 3.0 x 1023 Al atoms.
Secondly, is aluminum an atom or molecule? Aluminum is the second element in the thirteenth column of the periodic table. It is classified as a post-transition metal and a "poor metal". Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.
The law conservation of mass, because part of the mass can be converted into energy
also, the elements are changing during nuclear reactions, new elements are formed
