Explanation:
unicellular organism are single celled organisms and usually cab not be seen by our naked eyes. Example:yeast, microscopic algae, bacteria and more
multicellular organisms are organisms that have two or more cells. Example plants, animals
<span>A
typical human karyotype has 23 types of chromosomes arranged from largest to
smallest. In males and females 22 of these chromosomes look exactly the same
and they are called autosomes. The 23rd pair of chromosomes is the sex
chromosome which differentiates males from females. Females have 2 copies of
the x chromosome. Males have a copy of both x and y chromosome to make the 23rd
pair. <span>
<span>Chromosomes can also have abnormalities that
result to different conditions and identifiable traits. A most common
chromosomal abnormality is the condition called Down Syndrome, where chromosome
21 has a third copy because of an abnormal cell division.</span></span></span>
Answer:
Sensory adaptation.
Explanation:
When the sensory receptors are exposed to a constant stimulus for a prolonged period, the receptors decrease their ability to respond and this leads to a decreased sensitivity of the stimulus. This phenomenon is referred to as sensory adaptation.
Sensory adaptation occurs in all of our five major senses. From taste to smell, touch, sight and hearing. This mechanism is used by the body to ignore trivial and unimportant stimuli and direct our attention to other stimuli around us.
Other examples of sensory adaptation are;
A) When we adapt to constant noise coming from a particular source such as a disco hall.
B) When we no longer notice the smell of our deodorants.
C)When the eyes adjust and adapt to a dark room.
