Answer:
Summer
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Its A because there has to be a roman numeral to indicate which net charge of iron was used
The correct answer is : <span>Neon is inert because its outermost shell is complete.
Ne atomic number is 10 and has an electronic configuration of 1s</span>² 2s² 2p⁶.The outer shell is complete therefore Ne is inert, in other words inactive as its very stable with a complete outer shell.
Nitrogen is not inert as its atomic number is 7 and electronic configuration is 1s² 2s² 2p³. therefore valence electrons are 5, it needs 3 more electrons to gain the complete outer shell configuration. Therefore this statement is incorrect.
F has 7 valence electrons and needs only one more electron to complete its outer shell whereas O has 6 valence electrons and needs 2 electrons to complete its outer shell. Since F only needs one electron and O needs two electrons, F is more reactive than O therefore third statement is incorrect
F is more reactive than Ne as Ne is inert, however F needs to gain one electron and not lose, to fill its outermost shell therefore this statement too is incorrect
Answer:
Look at the picture.
Explanation:
On stage one binding of a substrate occurs (and also the geometry of active site may change) and water comes to the site. On stage two the hydrolisis takes place and on stage 3 products deabsorb from the enzyme.
