The weather man said the relative humidity will be high today
Answer:
Explanation: The reactivity of metals increases as you move left in a period and as you move down in a group, so Marie needs to know the period and group of the element inside each box. Boxes that show locations in groups 1 or 2 or in period 8 contain the most reactive elements.
Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
Glycolysis uses 2 ATP and produce 4ATP. So the net gain is true.
Oxygen is used in the Electron Transport Chain as the final electron recipient from complex 4 cytochrome a₃.
Explanation:
Glycolysis is the process which is common in all forms of respiration where glucose is metabolized into pyruvate. This process is very essential to continue the next steps of different respiration. Glycolysis requires 2 molecules to process substrate level phosphorylation to convert glucose to glucose 6 phosphate and fructose 6 phosphate to fructose 1, 6 bisphosphate. But it produces 4 ATPs. Thus net gain is 2ATP.
In ETC, the hydrogen carriers NADH and FADH gives off the hydrogen to reduce the complex 1 and 2 respectively and itself gets oxidized. Thus the electron given off is transferred between 4 complexes to finally give off to oxygen to form water.
Answer:
No
