Answer:
C. Shawna will walk along the meter stick and count how many steps she takes. She will then walk off a space of 1 m x 1 m
Explanation:
This procedure is likely to be the least accurate because it is difficult to be precise when measuring by taking steps.
<span>The enzyme is: ATP synthase.
ATP synthase is an enzymatic protein complex found in the mitochondrial ridges, the thylakoid membrane, and the plasma membrane of bacteria and archaea. The role of this membrane protein is to synthesize adenosine triphosphate (ATP) from the proton electrochemical gradient of protons maintained by the respiratory chain and adenosine diphosphate (ADP), as well as inorganic phosphate, according to the following reaction:ADP + Pi → ATP.
The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.<span>A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another.</span></span>
Explanation:
symbitotic: close ecological relationship between two or more organisms that live in close contact
mutualism is a symbiotic relationship in which both organisms benefit;
parasitism is a symbiotic relationship in which one organism benefits while the other organism is harmed
commensalism one organism benefits, the other neither benefits nor is harmed
:commensalism: answers will vary; lesser long-nosed bat/saguaro cactus; human and pet dog
Mutulism: answers will vary, human and eyelash mite, clownfish.and sea anemone
parasitism answers will vary, caterpillar and wasp, human and tapeworm
