Answer:
eutrophication
Explanation:
Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.
Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.
The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.
Answer:
B. Ataxia
Explanation:
Ataxia is a medical condition that is characterized by impaired balance or coordination as a result of a damage to the cerebellum or nerves and muscles that control coordination and voluntary movements. Alcohol intoxication, certain medications, stroke, cerebral palsy, degeneration of the brain, are some of the causes of ataxia. Individuals suffering from ataxia might exhibit signs like unsteady gait, difficulty with speech, lack of eye coordination, etc.
Answer:
See the answer below
Explanation:
Oxygen gas is produced during photosynthesis by photolysis of water in the chloroplasts of algae and green plants and in the thylakoid of cyanobacteria. The chlorophyll of photosystem II absorbs light energy which leads to the excitation and knocking out of an electron within the photosystem.
The energy released as a result of returning the electrons to the ground state in an acceptor molecule is used in splitting water molecules into hydrogen and oxygen. The electron released from the splitting of water replaces the one knocked out from the photosystem II while oxygen atoms from two water molecules combine to form diatomic oxygen which is later released as oxygen gas.
The whole process of photolysis of water and the release of oxygen gas happens during the light-dependent reaction of photosynthesis.
Answer:
I believe its the left frontal lobe (correct me if I'm wrong)
Explanation:
Answer:
cancellation
Explanation:
A factor in the numerator is <em>cancelled by dividing it</em> by the same factor in the denominator. The quotient is 1, the multiplicative identity element.
