What kind of variation is exhibited by human bloods?

Biology
1 answer:
kotykmax [81]3 years ago

<span>Blood provides an ideal opportunity for the study of human variation without cultural prejudice.  It can be easily classified for many different genetically inherited blood typing systems.  Also significant is the fact that we rarely take blood types into consideration in selecting mates.  In addition, few people know their own type today and no one did prior to 1900.  As a result, differences in blood type frequencies around the world are most likely due to other factors than social discrimination.  Contemporary Japan is somewhat of an exception since there are popular Japanese stereotypes about people with different blood types.  This could affect choice in marriage partners for some Japanese. </span>All human populations share the same 29 known blood systems, although they differ in the frequencies of specific types.  Given the evolutionary closeness of apes and monkeys to our species, it is not surprising that some of them share a number of blood typing systems with us as well. When we donate blood or have surgery, a small sample is usually taken in advance for at least ABO  and Rh  systems typing.  If you are O+, the O is your ABO type and the + is your Rh type.  It is possible to be A, B, AB, or O as well as Rh+  or Rh- You inherited your blood types from your parents and the environment in which you live cannot change them.

The bladder is in the _____ region. a. hypogastric b. right lumbar c. left lumbar d. epigastric
Anastasy [175]

The <u>bladder </u>is in the hypogastric region.

Hypogastric Region- The structures around the pelvic bone are located in the hypogastric area. These include the prostate in men and the womb and ovaries in women, as well as the bladder, a section of the colon and rectum, the anus, and several reproductive system organs.

Bladder- A little above and behind pubic bone in the pelvis, the urine bladder is a muscular sac. The bladder is roughly the size and shape of a pear when it is empty. The kidneys produce urine, which then passes via capillary called ureters and into the bladder. Urination can be restricted and rare because to the bladder's ability to hold pee.

likoan [24]
This process is called as imprinting. It occurs at a particular stage of life and is, therefore, a phase-sensitive learning process. It can be of many types, including filial imprinting, where an offspring gains some of its behavioral characteristics from the parent, or sexual imprinting, through which desirable characteristics of a mate are recognized by a young animal.

List the ocean regions that have the highest sea surface salinity
AlladinOne [14]

<u>Answer</u>:

The high sea surface salinity can be observed in the Pacific Ocean, the Indian Ocean, the Arabic ocean and the Mediterranean sea.

<u>Explanation</u>:

Due to rainfall and evaporation of water from sea the density varies with varying salts and minerals concentration that aggregate at the surface. The salinity in the seawater varies according to the amount of evaporation from a particular area.

Low salinity water is found in polar and subpolar regions that are near to the equator. Regions of high salinity are observed in the seawater which is centered around 30 degrees north and 30 degrees south to the equator due to the excess evaporation in these areas.
