I think all organisms are made up of one or more cells and cells are the basic units of life and all cells arise from pre-existing cells.
The genetic code is broken down into a series of codons on the mRNA. Each codon consists of 3 nucleotides which (normally) correspond to a single amino acid (e.g. AUG codes for methionine). I say normally because you can also have a codon indicate a stop codon (so no amino acid will be inserted and instead the polypeptide chain will terminate). This mRNA molecule with its list of codons will instruct a ribosome to synthesize a protein according to this code.
This code is the set of rules - based on the triplet or codon. This triplet code is universal - all organisms use the same codons to specify the placement of each of the 20 amino acids in a protein.
Hey there,
Your question states: <span>Which reason provides the best explanation of why a bar graph was selected to show the data in the table?
1.
Bar graphs are used to compare separate items.2.Bar graphs are used when data are continuous.
3. Bar graphs are not good for categorical data.
4. Bar graphs are the easiest to construct and to read.
Your correct answer would be (</span><span>
Bar graphs are used to compare separate items.)
When you see a (bar graph), you would see the different details in each bar. They show you different rating or uses of each subject.
(There would be a attachment below to show you)
Hope this helps.

Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes . Meiosis also produces genetic variation by way of the process of recombination .
Explanation: Meiosis is important for three main reasons : it allows sexual reproduction of diploid organisms , it enables genetic diversity , and it aids the repair of genetic defects .

The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water.
