Explanation:
The possible cause of the fish death in the lake near the park is that an algal bloom has drained the lake of oxygen.
The green slime on top of the lake are the growing algae.
- This condition is caused by eutrophication.
- It occurs when nutrients are enriched in a water body causing the growth of algae.
- Algae bloom causes the depletion of oxygen levels in the ocean.
- They block off plants from producing oxygen and enriching water with it.
- Fishes need oxygen for their life actions.

Etioliation means that you water plants that are planted in an area with little to no sunlight. This results in weak stems, smaller leaves, yellow color, etc. The seedlings that are grown in the dark are known as "skotomorphogenesis." Etiolation comes from something called "Auxin's" and Auxin's are moved from the top of the plant to the bottom which creates lateral buds. Typically, etiliation results in the chances being raised for the plant to receive sunlight but causes underiable symptoms.

Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.
Decomposers don't obtain energy, they release it into the environment.
