Answer:

hypoxia

Explanation:

Hypoxia is a condition of low or insufficient oxygen.

Eutrophication is the enrichment of water bodies.

The enriched water bodies causes algal bloom.

The algae compete for resources and this results in the death of some.

The bloom and the death of some algae results in the depletion of oxygen from the water body.

Trout and other fishes starts dying as a result of inadequate oxygen in the water.

Eutrophication results in the death of trout and other fish as a result of asphyxiation from the lack of oxygen. Eutrophication involves the enrichment of water by nutrients salts such as phosphates, nitrates among others, that causes structural changes of the aquatic ecosystem such as; increased production of algae and aquatic plants, depletion of fish species, deterioration of water quality and other effects that impact negatively the aquatic ecosystem.

Vsevolod [243]

Answer:

The correct answer is a increase in 3-phosphoglycerate levels and a decrease in RUBP levels.

Explanation:

NADPH is a reducing equivalent that is produced during light reaction of photosynthesis.The NADPH that is produced during light react is utilized in the dark reaction.

A decrease NADPH formation in the chroloplast will in turn decrease the formation of PGALD from phosphoglyceric acid(PGA).Some PGALD are used in the regeneration of ribulose bis phosphate(RUBP).

From this point of view it can be stated that decrease in NADPH level decreases PGALD level which in turn decreases RUBP levels.

As NADPH production is decreased in the chloroplast more phophoglyceric acid or 3-phosphoglycerate will accumulate thus the cellular level of PGA is increased.

iogann1982 [59]

Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

The central dogma theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

Replication
Transcription
Translation

Replication is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

Transcription is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or translation process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

The correct option is b.
