Answer:
Repolarization
Explanation:
Complete repolarization is achieved by the sodium pump. This actively pumps all the Na+ ti the outside and all the K+ to the inside. The pump requires energy in the form of ATP and is inhibited by metabolic poisons. Entry of Na+ is immediately followed by an increase in the permeability of the membrane to K+. These diffuse rapidly to the outside due to the concentration gradient. Being positively charged, the K+ reverses the polarity of the membrane making the outside positive.
Answer:
all living organisms are formed from cells
all living cells reproduce
cells are the basic structural and functional unit of life
Explanation:
Hydrogen atoms are compressed
together by the enormous gravitational force
of the sun, causing them to fuse int a helium atom (which is heavier than
hydrogen), subatomic particles and enormous
release of atomic energy. The attached
picture shows the sequence of the main reaction
at the core of the sun.
Answer:
The probability of the study result being subject to bias while interpreting -------- it's a YES
Explanation:
Probability of Leukemia
A. Among traced group
= 4/1,870 persons.
B. Among self-reported group
= 4/443 person.
We can deduce
A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites
