Answer:
Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:
- They increase the nitrate levels in the soil which is a rich supplement for nitrogen needed by plants for their growth.
- They are easily available and user-friendly but should be used in regulated amounts as an excess of nutrients like nitrogen and phosphorus present in synthetic fertilizers enter the aquatic ecosystem.
<u>Explanation:
</u>
Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants. Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.
When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water. That is why such fertilizers should be used in regulated amounts.
Answer/Explanation:
If a protein has a quaternary structure it is formed when many subunits get together.
- true. The quaternary structure of a protein is the final stage in its assembly, when structures from multiple polypeptides come together, forming a multi-subunit protein (e.g. a dimer if 2, a trimer if 3 and so on)
Monomers form the secondary structure of proteins.
- false, they form the tertiary structure
The charges on the functions groups of the amino acids creates the beta pleated sheets and alpha helix structures that are the secondary level of structure in proteins.
- false, it is mostly the peptide backbone that causes the alpha helices and beta sheets to form
The order of the amino acids is the primary structure of proteins. - true. The amino acid sequence linked together by peptide bonds is the polypeptide sequence, which then forms increasingly complex structures when folded.
The tertiary structure of proteins is formed when the B sheets and alpha helices organize themselves into a more complex shape. - true. These complex structures can further interact with one another to form increasingly organized domains. The amino acid side chains possess different properties that form different bonds with one another.
The primary structure of proteins is formed from the amino groups on the proteins. - false, the primary structure is formed by the sequence of amino acids in the chain, determined by the mRNA sequence from which the protein is synthesised.
Answer:
Pretty sure its A.
Explanation:
I don't think it would be B. because they already wrote the Declaration of Independence, so why would they have him write a set of laws?
I don't think it would be C. because the Patriots were willing to go to war over this, hence the American Revolution.
This is by process of elimination so i'm not totally sure this was right. Hope it helps though!
