Light energy is transferred to a chlorophyll reaction center where electrons become energized.
- A protein in the electron transport chain, pumps H+ ions from the stroma into the thylakoid space
- Electrons from the electron transport chain close to photosystem II replace the elctrons lost in photosystem I
- Electrons from Photosystem I become energized and escape photosystem I and move down the second electron transport chain.
- H+ ions flow down the concentration gradient through a channel in ATP Synthase, releasing energy in the process
- Electrons move down the electron transport chain, releasing energy
- Electrons move to an electron acceptor in the electron transport chain and electrons in photosystem II are replaced by the splitting of a water molecule
- Photosystem II receives photons in the form of light energy
- Water is split to replace the electrons in photosystem II
- At the end of the electron transport chain, the energized electrons and an H+ ion are used to reduce NADP+ to NADPH
- ATP uses energy to add a phosphate to ADP forming ATP
Answer:
Explanation:
"Animals, plants, and fungi often have many different organs whose different functions are integrated, enabling multicellular organisms to maintain themselves, grow, and reproduce. Two or more tissues that work together to get a job done form an organ. A group of organs that works together to perform a certain job is an organ system. Organ systems found in plants, animals, and other multicellular organisms allow these organisms to function more efficiently."
A. 1 RR: 2 RW: 1 WW
b. 1 red snap dragon: 2 pink snap dragon: 1 white snap dragon flower
Answer:
Population is a collection of individuals of a species living in a defined area
Explanation:
Population:This is a collection of individuals of the same species occupying the same space and able to interbreed freely with one another when individuals of different sexes are brought together.
A species of animals may comprise a single cohesive population or may contain many geographical distinct populations.
Example:A population of Agama lizards in a Campus located in China.The whole human race, Homo sapiens comprising the black, Mongolian,red and white is a population.A population of <u>Cercopithe</u><u>c</u><u>us</u> <u>erythrogaster</u><u> </u>(Monkeys).
Answer:
C
Explanation:
In 1839, Theodore Swhwann, a German Zoologist examined bits of animals under a microscope and observed that animals were composed of cells.
