Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
Answer:
Type O
Expresses the B agglutinin
Expresses all the major antibodies
The most common US blood type
The universal donor
Type AB+
Expresses all of the major antigens
Expresses the D antigen
The least common US blood type
The universal acceptor
Expresses the Rh factor
Expresses A agglutinogen
Explanation:
Blood type is a grouping of blood into classes that have the presence or absence of antibodies and or antigens on the red blood cell surfaces
The class of blood determines whether the antigens are glycolipids, carbohydrates, proteins or glycoproteins of Type O
The blood type of a person is an inherited trait from both parental gene. There are various blood grouping system with the ABO and Rh systems being the most important as they determine the suitability of a given blood for transfusion.
