CAN SOMEONE PLEASEEE HELP ME WITH THIS SCIENCE QUESTION THANK YOU !!​

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

Habitat destruction :

Habitat destruction is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or die, thereby reducing biodiversity and species abundance.

Answer:

Neon has eight valence electrons and it does not have cations or anions.

Explanation:

Neon is a noble gas, meaning it has already fulfilled the octet rule and has eight electrons in its valence electron shell. Hence, it does not want to lose or gain any more electrons, and does not have cations or anions.

Hope this helped!

Explanation:

Long bones are those that are longer than they are wide. The end of the long bone is the epiphysis and the shaft is the diaphysis. When human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum
