Answer:
Marine ecosystems are characterized by factors such as availability of light, food and nutrients. Other factors that affect marine ecosystems include water temperature, depth and salinity, as well as local topography. Changes in these conditions can change the composition of species that make up the marine community.
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:
Explanation:
Psychrophile is a type of organism and bacteria that can grow and reproduce in very low temperatures. Besides low and cold temperatures these organisms adapt to high pressure and high concentrations of salt. Their body has adapted to these types of harsh environments by having a body that keeps them from freezing. Their enzymes had evolved to engage in activities such as activity-stability-flexibility as a method for adapting to the cold. This type of bacteria can grow in refrigerated temperatures and they could be found in foods and dairy products.
Answer: true
Explanation:
Organisms within a population must compete for resources to survive. T: The least-equipped organisms may not survive. ... -A process by which an organisms better adapted to their environment tend to survive, reproduce, increase in number, and pass their traits to succeeding generations.
