Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)
Answer:
Reflex action is the sudden uncontrolled reaction towards a certain stimuli eg response to hot iron
Reflex arc is the path taken by reflex action to a certain stimuli
Diagram depends to
Receptor(eg skin), receptor nerve(sensory neurone),centre reflex arc(spinal cord most of reflex action) they met relay neurone, motor neurone and ends at reflexor (eg muscle)
Answer: Mass
Explanation: i hope i helped i did that yesterday and it was right but i hope it is??
La síntesis de proteínas se realiza en los ribosomas situados en el citoplasma celular. En el proceso de síntesis, los aminoácidos son transportados por ARN de transferencia correspondiente para cada aminoácido hasta el ARN mensajero donde se unen en la posición adecuada para formar las nuevas proteínas.
Answer:
Osteoblast, osteocytes and osteoclasts are responsible for breaking down bone during remodeling.
Explanation:
The process which is responsible during bone formation in equally in initial and later stages of remodelling, they are the bigger cells which are responsible for the synthesis and mineralisation of bone. Osteocytes are the rich in cells in the bone tissue, which is helpful in detection of the mechanical loading, also manages the in bone formation and bone resorption. Osteoclast are cells that disintegrate the bone to start normal bone remodelling and also contemplate bone loss in pathologic condition by growing its resorptive capacity.
