During a annular solar eclipse the moon is at blank and does not fully cover the blank of the sun

An annular solar eclipse is when the Moon covers the Sun, but not completely. A ring is left around the Moon where the Sun's light can still be seen. During an annular solar eclipse, the Moon is at apogee, so it is far enough from Earth where it can't completely block out the Sun.

Why is there a ring left around the Moon where the Sun's light can still be seen?

- The Moon's orbit not perfectly circular

- When the Moon is closest to Earth, it is called "perigee".

- When it is furthest, it is called "apogee"

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
