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:
The pointer pointing to the grey and white balls are either proton or nuetron i van't really tell cause their grey and white.
The whole clster of balls is the Nucleus
The black balls on the lines are electrons
And the lines are the energy level
Explanation:
Well, after 1 half life, depending on whatever the amount is, 50% of the original content and or remaining content will undergo decay, as it is unstable.
Original content - 200g
1 half life - 100 g
2 half life - 50 g
3 half life - 25 g
The correct solution would be D. 25 g.
The law of conversation of mass states that you cant create or destroy matter.By applying these to chemical changes, it implies that the left hand side of the reaction must balance with the right hand side of the reaction equation as you can neither create nor destroy atoms. this gives us a powerful tool to predict chemical reactions and the overall stoichiometrey
of chemical reactions
