The answer is A, as most sewage treatment plants use bacteria to break down and remove nutrients. The main water pollution problem caused by sewage effluent is eutrophication, related to the release of nutrients into rivers and lakes. Nutrients such as nitrogen and phosphorus ions result in high algal growth. Some algal blooms release toxins, and algal blooms also disrupt the natural dissolved oxygen concentration cycles. Fish kills are often because eutrophication has resulted in anoxic conditions.
Anyway, wastewater treatment plants utilise bacteria to facilitate nitrification or denitrification, which removes ammonia and nitrates/nitrites, respectively.
Answer:
The correct answer is - Cyanobacteria; Horizontal gene transfer
Explanation:
According to the endosymbiotic theory it is believed that the eukaryotic plastids (mitochondria and chloroplasts) have developed from symbiotic bacteria, such as cyanobacteria and alpha-proteobacteria.
During this symbiotic process, some genetic material may have been move in between the symbiotic counterparts in a process called Horizontal gene transfer or lateral gene transfer.
thus, the correct answer- Cyanobacteria; Horizontal gene transfer
The answer will be 1. Energy from photosynthesis will transfer to the snake.
Answer:
Skin cells would die and not be replaced.
Explanation:
Cycloalkanes
are saturated hydrocarbons with monocyclic structure.
<span>This
means that cycloalkanes contain hydrogen and carbon atoms arranged in a
structure containing a single ring (sometimes with side chains), with all of
the carbon-carbon bonds single. The examples of cycloalkanes are cyclopropane,
cyclobutane, cyclopentane, cyclohexane…</span>
