Answer:
1.) Are tightly coiled bundles of DNA
2.) Carry many genes
3.) Are found inside the nucleus of eukaryote
4.) Can be used to diagnose genetic disorders
Explanation:
A chromosome is a thread-like structure made up of DNA. The chromosomes are made of DNA which are tightly coiled around protein.
Chromosomes carry hundreds and thousands of genes. The number of genes in a cell outnumbers the number of chromosomes.
In eukaryotic cells, all the chromosomes are found inside the nucleus of eukaryote.
The chromosomes and DNA can be examined so as to diagnose genetic disorders.
Answer:
A) the number of electrons in the outer shells.
Explanation:
The Bohr's model of the atoms shows that electrons orbits the nucleus in energy levels that are discrete and quantised. Orbital electrons are pulled by the nucleus. The nuclear pull is strongest on the shells closer to the nucleus and weakest as we reach the outermost sphere.
From this model, we see that chemical properties are governed by how much electrons an atom is ready to lose from its outermost shell in which the energy is the lowest. It is the electrons in the outermost shell or valence shell that determines how atoms would behave chemically.
For the answer to the question above, t<span>he energy that is required to break all the carbon-hydrogen bonds in methane is 891 kJ/mol. In 0.1 mol of methane, you would need 89.1 kJ.
I hope my answer helped you. Have a nice day</span>
cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid are the 2 isomers with the molecular formula C₄H₄O₄.
<u>Explanation:</u>
Isomers are the structures having the same molecular formula but their is a difference in their structural formula and this concept is known as isomerism.
Here we have the molecular formula C₄H₄O₄ and it may be dicarboxylic acid and it may be exist as geometrical isomers as cis-2- butene-1,4-dioic acid and trans-2- butene-1,4-dioic acid.
The isomers are given.
Answer:
262.821 g/mol is the molar mass of Beryllium diiodide.
