The classification is in this order: Kingdom, Phylum, Class, Order, Family, Genus Species.
The kingdom is the largest group, it contains the largest number of organisms who are the least related.
The species is the smallest group, it contains the least number of organisms who are closely related.
As you go down, from "Kingdom", species become more closely related.
So species in the same family are MORE closely related than species in the same class.
Answer:
The chance of a normal couple having a child with down syndrome is 1 to 600 births.
Explanation:
Down syndrome is a genetic flaw that occurs when the fetus is being formed.
A human cell considered normal has 46 chromosomes, divided into 23 pairs. For some unknown reason, an error may occur at the beginning of embryonic development and an extra chromosome is created, which binds to par 21. The result is cells with 47 chromosomes. This causes the said syndrome.
It is important to know that this failure happens at random. It is nobody's responsibility. It has not been proven to date that lifestyle, actions during pregnancy, smoking, drinking, medicines, environmental factors or kinship between the couple can influence this occurrence. She is not contagious either. The likelihood of a normal couple having a child with the syndrome is approximately 1 to 600 births.
Answer:
Spinous process
Explanation:
The rhomboideus minor muscle originates on the <u>spinous processes</u> of vertebrae T2-T5
The rhomboideus minor muscle forms part of the superficial group of back muscles. The muscles in the superficial group are immediately deep to the skin and superficial fascia. They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).
These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.
The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.
Answer:
In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.
<em>The cladogram in the above picture shows that the limbs originated after the jaws. </em>
The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.
