After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
- Algal bloom: the nutrients facilitate the rapid growth of algae
- The bloom of algal species results in the death of underwater plants as a result of inadequate light.
- The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
- Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia
Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Well assuming the original cell is a prokaryotic, you wouldn't be able to remove the nucleus because prokaryotic cells don't have a nucleus to begin with. if this doesn't help then: The cell would lack genetic information.
The correct answer for this question is "Epiglottis". The Epiglottis is responsible for cutting off the passage way to the airway while swallowing/eating food to prevent the food from being inhaled by the body.The Epiglottis has a leaf-like shape structure with a cartilage that covers the passage way into the air ways of the body.
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.
The question is incomplete. The statements are the following:
(1) The new animal must get the DNA from two different parents, not just one cell.
(2) Mutations could occur that change the cloned animal into a completely different species.
(3) Recombination of the cells as they are cloned will make the resulting pet act differently.
(4) The environment could influence how genes
are expressed, changing how the animal looks and acts.
Answer:
4. The environment could influence how genes are expressed, changing how the animal looks and acts
Explanation:
An organism is product of the interaction between genes (inherited characters) and environment (non-inherited)
