Answer:
Meiosis creates four haploid reproductive cells called gametes.
Answer:
There are three basic methods to study animal behavior; these methods include observational, experimental and comparative. To identify if a behavior is proximate or ultimate, Niko Tinbergen developed four questions to identify different behaviors done by an organism.
a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young
Answer:
Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):
NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2
Explanation:
The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.
Answer:Fowl pox is a slow-spreading viral disease of chickens characterized by lesions on the unfeathered skin areas (dry pox) (Figure 1) and/or on the mucous membranes of the oral cavity, larynx, and trachea (wet pox) (Figure 2).
