Answer:
Answer is in the explanation.
Explanation:
Let's make a system of equations.
5x+10y=550
x+y=80
Now let's use elimination
-5x-5y=-400
5x+10y=550
__________
5y=150
y=30
Then subsitute 30 in for y to find x. This will leave you with x=50. You will have 50 $5 bills and 30 $10 bills. You can check by subsituting x for 50 and y for 30 in both equations to show why it is correct. Eliminating makes it easier to solve the system of equations.
You might have to be more specific. All of the following structures except what?
Complete question:
Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons
- Amino acid sequences determine the three-dimensional structures of proteins.
- Knowledge of the sequence of a protein can help to prevent mutations.
- The sequence of a protein reveals much about its evolutionary history.
- The sequence of a protein is necessary to determine its function.
Answer:
Knowledge of the sequence of a protein can help to prevent mutations.
Explanation:
<em>Amino acids connect to each other by peptidic bonds </em>to form a <em>linear polymer</em>. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.
The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of <em>hydrogen bonds between the atoms that form the peptide bond.</em>
<u>Protein functions depend on their aminoacids sequences</u><u>.</u> <u>The primary structure of the proteins determines the three-dimensional one</u>. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.
Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.
When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.

Answer:
B
Explanation:
Meiosis produces gametes that contain one complete haploid set of chromosomes
Meiosis is a reduction division, where the number of chromosomes in the daughter cells is reduced to half as compared to the parent cell. This set of chromosomes is called a haploid set or genome. The reduction from diploid to haploid occurs during Anaphase I of meiosis I, where homologous chromosomes separate and enter into two different cells. Meiosis takes place only in reproductive cells that divide to form gametes
So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'
hope that helps
