The streams and rivers in the drainage basins were the prairies are converted into farm land are mostly affected by the agriculture and its needs, as well as its consequences.
The agriculture demands water for irrigation, and most of this water comes from the streams and rivers, so that contributes to lowering of the water levels of the streams and rivers.
The agriculture also causes damage to the streams and rivers by polluting them. Namely, the pesticides, herbicides, and fungicides that are used for protection of the plants, partially end up in the low groundwater's, and in general, these waters are connected to the streams and rivers, so the pollutants end up in them, and that affects the biodiversity in them very badly.
Answer:
it d
Explanation:
b. glycerol is made of fatty acids.
proteins are made of amino acids.
nucleotides are made of nucleic acids.
The correct statement about macromolecules is 'Proteins are made of amino acids'. It should be noted that in other options, the statements have a part reversed and therefore they are incorrect.
The correct statement about macromolecules is 'Proteins are made of amino acids'. Macromolecules are large, complex molecules that have a high molecular weight. They are mostly built from single subunits, or building blocks, called monomers. In this context, amino acids are the monomers that make up proteins which are a type of macromolecule.
To provide some clarity on the incorrect options: `Simple sugars are not made of polysaccharides` but the other way around. Polysaccharides are complex carbohydrates that are made up of simple sugar monomers. Similarly, `glycerol is not made of fatty acids`, rather, it combines with fatty acids to form lipids. Lastly, `nucleotides are not made of nucleic acids`, but nucleic acids are made of nucleotides. So, it's important to understand the relationships between these biochemistry terms to correctly understand the nature of macromolecules.

d. Feathers
Answer:
The main function of RNA is to carry information of amino acid sequence from the genes to where proteins are assembled on ribosomes in the cytoplasm.
Explanation:
This is done by messenger RNA (mRNA). A single strand of DNA is the blueprint for the mRNA which is transcribed from that DNA strand. One of these active processes is protein synthesis, a universal function in which RNA molecules direct the assembly of proteins on ribosomes. This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to form proteins.
