The correct answer would be D) An observation that has a number associated with it.
Answer:
The correct answer will be-
1. Pupil
2. Retina.
Explanation:
Organisms are able to see the world around them thorugh the sense organs called the eyes.
The structure of eye contains various modified structure which include the membranes and the attached muscles.
When light enters the light through the dome-shaped structure called cornea which contains the convex lens converges the light and light enters the hole called pupil through which light enters and strikes or get focused on the retina present at the back of the eye.
The pupil is attached to the ciliary muscles which dilate and contracts in the response of the intensity of light as during high light intensity, the pupil constricts whereas during the low light intensity the pupil dilates to allow the maximum amount of light.
Thus, pupil and retina is the correct answer.
Answer:
fewer in number.
Explanation:
A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.
Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.
Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.
Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.
