The retina of the eye does all of the following except a. absorb light b. decrease visual acuity c. process images d. send visual information to the brain

(B). decrease visual acuity

Explanation:

Retina can be defined as the light-sensitive, innermost layer of eye that triggers the nerve impulses the brain and helps in formation of visual image.

Photoreceptors present in the retina are responsible for absorption of light. Retina also processes images and send visual information from optic nerves to the brain, where formation of image takes place.

Hence, all given functions are performed by retina, except decreasing visual activity.

Thus, the correct option to be filled in the blank is option (B).

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
