Answer:
Answered below.
Explanation:
A karyotype is defined as the size, shape, and number of chromosomes present in an organism.
An analysis is usually done on a karyotype to see if individuals have abnormal numbers or sizes of chromosomes. Such abnormalities may arise from;
Deletion: which implies that a chromosomal part is missing.
Duplication: where parts of a chromosome are repeated.
Translocation: which occurs when a chromosomal part breaks off and gets attached to another chromosome.
Nondisjunction: in which chromosomes do not separate from the parent cells.
Common chromosomal disorders arising from these abnormalities include;
Down's syndrome
Edwards syndrome
Turner's syndrome
Klinefelter syndrome
Prada-willi syndrome
Cri-du-chat syndrome
Patau's syndrome
Answer:
The answer is hormones.
Explanation:
Two of the main systems that control almost every action in our body are our nervous system and endocrine system which have to have inner communications and communication with our brain.
As stated in the question, nervous system uses neurotransmitters for communication which are chemicals released by neurons to generate electrical signals that make the communication possible.
The main mean of communication that our endocrine system uses is substances that are called "Hormones" which are produced by certain glands and organs in our body and are usually released into our bloodstream to effect the functions of other organs and our body. Hormones can be used for both communication of the endocrine system itself and for the communication of other organs and our brain.

No. The reason for this is that people who have hearing from both sides use the latency that comes to one ear compared to the other to determine the location of the sound. Judging by this, people who are deaf cannot determine a location of a sound because they cannot calculate the difference between one and other ear.
