Which term best describes the difference in colors of the birds below? 4 birds are shown. One has light brown feathers with dark
drek231 [11]

Answer:

genetic variation

Explanation:

Genetic variation refers to the difference in genetic content of organisms within a population. The genetic makeup of living organisms are made up of GENES, which exists in contrasting pairs called ALLELES. Each allele is responsible for variation in traits exhibited by the organisms. Differences in the allelic content of organisms of the same species leading to the display of varying phenotypic characteristics is referred to as GENETIC VARIATION.

This is the case in the example given in which four birds in a population possess a range of wing and feather colors i.e light brown feathers with darker wings, dark feathers with lighter wings, medium brown feathers with light wings, and medium brown feathers with very dark wings, all resulting from a variation in their genetic content. Hence, this is an example of GENETIC VARIATION.

Sequence for the movement of electrons during the light dependent reaction

Explanation:

1.These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.

2.The cyclic light-dependent reactions occur only when the sole photosystem being used is photosystem I. Photosystem I excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b6f, to another transport protein, plastocyanin (Pc), and back to photosystem

3.Light-dependent reaction. In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). ... Water, when broken, makes oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and by chemiosmosis, make ATP

4.The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
