ANSWER:
Problem faced include; habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, climate change etc.
EXPLANATION:
Problem:
Habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, and climate change are notable problems experienced by freshwater and marine fishes.
Solution:
Anthropogenic activities and stressors that rapidly threaten freshwater and marine fishes are curbed through legislation and other means to prevent extinction of fishes.
Through conservation programs that plans for individual species to more species of entire faunas of a particular location also boost population size and prevent hunting of threatened or endangered species in both realms.
Overtime, genetically modified fishes which can develop resistance to diseases are introduced to the realm.
Moreso, waste channels through which pollutants gets into the water bodies are well-treated for safety of fishes.
If the cell treated with a chemical that inhibits DNA synthesis is treated to undergo the process of the cell cycle, the phase that will be affected is the S-phase of interphase.
<h3>What is interphase?</h3>
The interphase stage of cell division is the resting stage between two successive divisions.
The interphase is further grouped into three phases namely:
- G1 phase
- S-phase or synthesis phase
- G2 phase
The synthesis phase of interphase is the stage where new DNA strand is synthesized, hence, if the cell treated with a chemical that inhibits DNA synthesis is treated to undergo the process of the cell cycle, the phase that will be affected is the S-phase of interphase.

Answer:
The correct answer is e. All of the above.
Explanation:
Sister chromatids are made during the synthesis phase of the cell cycle. In the synthesis phase, the homologous chromosomes get replicated and sister chromatids are produced so they are produced by duplication of chromosomes.
As sister chromatids are produced by replication, therefore, they are identical copies of parent chromosomes. These sister chromatids are joined to each other at centromere. They get separated during the anaphase of mitosis and moves to the opposite pole.
Therefore the right answer is e.
Answer:
A. Abrasion
Explanation:
<em>"In abrasion, one rock bumps against another rock. Gravity causes abrasion as a rock tumbles down a mountainside or cliff. Moving water causes abrasion as particles in the water collide and bump against one another."</em>
