An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.
Answer:
Bacillus is a Heterotroph!
Explanation:
They depend upon tissues and waste from the other living organisms.

Answer:
(3) could be mistaken for food by some species, working their way up the food chain
Explanation:
Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by
- Ingestion
- Introduction and transference in the trophic web
- Interaction with other contaminants
- Microinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.
Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.
The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.
Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.
I believe the false answer is 1) Dynamic equilibrium is seldom maintained long term in environmental systems.
Answer:
Yes. Levels of Carbon dioxide must be equal in proportion to metabolic rate of the system. is a product of cell respiration and should be monitored.
Explanation:
Levels of carbon dioxide must be equal in proportion to metabolic rate.
Carbon dioxide is a product of cell respiration and should be monitored to avoid surfocation and likes
As the temperature of the system(or body) increases, oxygen level decreases leading to increase in carbon dioxide level which is very dangerous for any system or an organisms. This can leading to Astma and other respiration problems.
