Answer: gastrula, archenteron, blastospore
Explanation:
a) Gastrulation is a dramatic reorganization of the hollow blastula into a two-layered or three-layered embryo called a gastrula.
b) Invagination of cells into the blastocoel forms a tube called the archenteron.
c) The open end of the archenteron is called the blastospore..
The answer to the question above is letter B. In humans, having freckles is the result of a dominate gene and not having freckles is a recessive trait. If the freckled man is homozygous and the woman doesn't have freckles then the child would have freckles.
It would be considered E
Since
Parasitism is when one be benifits at the others harm, normally has a host and parasite. Like a tic and dog. The tic is the parasite and the dog is the host
Competition is when two animals fight for prey, territory, or mates. Like when two male lions fight to prove strength and the winner leads the pack while the other is kicked out and must go find there own pack
Mutualism is is when two animals are counted as mutuals. Like the alpha male and female that believe they are equals
Predation is when one animal eats another it normally has a prey and a predator Like the cat and the mouse. The mouse is the prey and the cat is the predator
Commensalism two animals live peacefully in the same habitat. Like the cow and the cowbird both love in harmony
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
