Answer:
The chlorophyll pigment have photosystem 680/ PS I which captures the sunlight. Then the pigments gets excited and photosynthesis starts. Without chlorophyll photosynthesis can't happen.
Explanation:
Photosynthesis occurs in the chlorophyll pigment of the plant. They have the capacity to trap light energy and convert its energy to form glucose and oxygen.
The chlorophyll is a double layer membrane structure. In it two photosystems works i.e. photosystem I and photosystem II. In the photosystem I light is trapped.
In the chlorophyll thylakoids are present which have photosystem 680. It captures the photons coming from the sun. The photons are the light of different wavelengths which are absorbed by plants.
The photon have more energy, and when it comes in contact with PS 680, the pigments get excited. Then they release high energy electrons which helps to form ATP, NADPH. Because it is a light dependent reaction.
Glucose and oxygen are formed in the stroma as it does not require light. It is a light independent reaction.
Therefore, chlorophyll is first require to capture photons coming from sun.
Answer:
D.Georgia to Alabama
Explanation:
There are records of manatee sighting during the summer months in areas such as Alabama, Georgia and South Carolina. They migrate north in the summer months.
The manatees do not withstand temperatures below 21 degrees Celsius.
Most manatees migrate seasonally over long distances between a northern warm season range.
In winter the manatees are concentrated in Florida.
Answer:
Energy produced by respiration is stored in Adenosine triphosphate, also known as ATP.
Explanation:
Cellular respiration uses glucose and turns it into ATP. Using NADH and FADH₂ (Created in the Krebs Cycle) in the Electron Transport Chain, we can produce 32-38 molecules of ATP. ATP carries a lot of energy, and your cells and body uses ATP (ATP is basically like a large battery).
Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.
