Hydrogen atoms are compressed
together by the enormous gravitational force
of the sun, causing them to fuse int a helium atom (which is heavier than
hydrogen), subatomic particles and enormous
release of atomic energy. The attached
picture shows the sequence of the main reaction
at the core of the sun.
Answer:
1) IRIS
2) LENS
3) RETINA
4) Fovea Centralis
Note: Answers 1 - 4 follows question pattern
Explanation:
The PUPIL is the hole in the MIDDLE of the IRIS of the eye, through which light passes to be focused on the RETINA.
The IRIS is the contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
ACCOMMODATION is the change in the adjustment of the eye lens to help focus light ray.
RETINA helps to receive light rays that the lens has focused. It contains two cells: rods and cones
Fovea Centralis is at the center of the retina responsible for sharp and accurate vision, also it is where cones cells cluster.
Answer: a small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of light.
