Answer:
Paraquat serves as a herbicide.
Explanation:
Coral bleaching wasn't induced by paraquat since it is a herbicide aimed at eliminating weeds, not algae. Coral hosts small algae essential for its coloration, hence applying paraquat wouldn't affect these algae, thus preventing coral bleaching. In contrast, if a different chemical that targets algae is used, it results in coral bleaching and turns the coral white.
Prokaryotic cells: do not possess membrane-bound organelles, and are relatively small—generally under 10 μm in size.
Both types of cells: utilize ribosomes for protein synthesis and contain DNA.
Eukaryotic cells: feature a complete set of DNA located within multiple chromosomes.
Specifically, prokaryotic cells lack a nucleus and membrane-bound organelles, resulting in their ribosomes floating freely within the cell. In contrast, eukaryotic cells possess a nucleus and membrane-bound organelles. Additionally, their DNA is associated with proteins and organized into chromosomes within the nucleus.
Answer:
Remove all wildlife from the bay.
Explanation:
An algal bloom refers to the excessive proliferation of algal species within a body of water, often triggered by nutrient overload from pollutants, a process known as Eutrophication.
The occurrence of an algal bloom signifies pollution within that water body, leading to bacterial degradation of the pollutants. As bacteria metabolize pollutants, they consume large amounts of dissolved oxygen in the water, drastically decreasing oxygen levels. This situation poses a significant threat to aquatic organisms that depend on oxygen, resulting in possible animal suffocation or starvation.
Therefore, the priority action upon detecting an algal bloom in a bay is to evacuate all wildlife to avert mass deaths.
Common side effects from substance abuse often include symptoms such as anxiety, excessive excitement, difficulties in concentration, lack of coordination, and tremors. Drugs like cocaine, nicotine, ecstasy, and amphetamines fall under this category. However, any substance that induces a feeling of euphoria or a 'high' can potentially become addictive.
