Answer:
Copper,natural gas, petroleum
Explanation:
Copper and petroleum are found in South America. Most of the mines in the world are found in South America and they generates income to the Aldeans countries.
Also, petroleum reserves are found South America and they are very important, but not as as much as mineral reserves. Venezuela is the country that has the largest oil reserves, other countries like Peru or Ecuador have important reserves. natural gas is very common and present in the region, and it is also an important resource.
Answer:
isosmotic; isosmotic; hyperosmotic; hypoosmotic.
Explanation:
The osmotic pressure is important for the flow of molecules in the different compartments of the different organs of the body. The osmosis process is energy independent process that transfers the molecules along the concentration gradient through the semi permeable membrane.
The plasma and tubular fluid are isoosmotic with each other means they have same osmotic pressure when it enters the Bowman's capsule that maintain their osmolarity. The fluid still remains isoosmotic when enters at the beginning of loop of Henle. The fluid then becomes hyperosmotic because it shows a large amount of difference between the solutes as compared with the plasma fluid and contains large amount of ions at the tip of Loop of Henle. The fluid then become hypoosmotic because now it contains few solutes as compared with the plasma at the deginning of the distal convoluted tubule. This osmolarity difference helps in the production of urine.
Thus, the correct answer is (c).
Banana peels can be decomposed by bacterial action, so they are biodegradable.
Answer:
5'UAGCGAGG3'
Explanation:
RNA does not have the Thymine base. Instead, its place is was taken by Uracil. Therefore during transcription, an Adenine on the DNA is paired with a Uracil on the RNA. Uracil can, nonetheless, also be formed by deamination of Cytosine resulting in mutation due to mismatched base pairing during replication.
