<span>Heavy metals like mercury enter waterways by industrial dumping and poor regulatioin of effluent, and they also enter soil through a similar manner, in which waste is disposed of imporperly. Another source of heavy metals are the gases leaving industry carrying these metals. The metals fall as a solid on to soil and water ways. Therefore, the answer is D.</span>
All the answers are on the actual periodic table. You should never be told to remember it so I think this is a recourse you are allowed to look at whilst doing your homework lol :) all the answers are written on it hope it helps
Nitrogen=2, Hydrogen=8, Carbon=1, Oxygen=3
Hydrogen=4, Carbon=2, Oxygen=2
Iron=1, Nitrogen=2, Oxygen=6
Answer:
The transfer was essential to understand the mutation and the possibility of new, more resistant strains in microorganisms.
Explanation:
the transfer of microorganisms is based on the transfer of genetic data through conductive pathways that penetrate the membranes, called pili or genetic bridges.
These mutated genes with higher resistance are transmitted and resistance is generated in entire populations and even species.
Answer is: c) CAM.
CAM (crassulacean acid metabolism) is a carbon fixation pathway.
In plants with CAM carbon fixation, carbon dioxide is stored as the malic acid malate in vacuoles at night.
During the daytime, the malic acid is transported to chloroplasts where it is converted back to carbon dioxide, which is then used during photosynthesis.
Malic acid is an organic dicarboxylic acid with the molecular formula C₄H₆O₅.
