Acute renal failure (ARF), commonly referred to as acute kidney injury (AKI), is a brief period of kidney damage or malfunction which lasts some few hours to a few days.
The kidneys struggle to maintain the proper balance of fluids in the body when waste products accumulate in the body.
AKI includes 4 stages:
(I) initiation,
(II) oligo-anuria,
(III) polyuria, and
(IV) restitution.
The onset phases of ARF are best described by stage 1, which is called Initiation.
The initial phase of kidney damage is characterized by a 25% reduction in renal blood flow as well as tissue oxygenation, as well as a decrease in urine output to less than 0.5 mL/kg/hr, as a result of events including such blood loss, dehydration, burns, diabetes insipidus, or infection.
This phase last hours to days.

Answer:
Blood-brain barrier.
Explanation:
Blood brain barrier may be defined as the barrier between the blood capillaries and the component of the brain tissue. This blood brain barrier provide protection against the pathogens present in the blood.
The blood-brain barrier uses tight junctions that prevent the entry of microbes in the underlying tissue. The tight junctions allows only the entry of some selected particles and prevent the entry of other particles.
Thus, the correct option is (3).
Answer:
50% tongue and 50% no tongue.
Explanation:
Upper case T is dominant over lower case t recessive, so we can see that there are two Tt and two tt.
you have to make the Table like this.
T t
t Tt tt
t Tt tt
Final answer 50% tongue and 50% no tongue.
The mistake is fixed.
Answer:
Dispersal
Explanation:
It should be understood that there was a point in time when the collard lizards were going into extinction. This is due to some certain human activities such as bush burning, which caused the death of this particular creature and others.
Therefore, this activity led to the dispersal of the remaining member of the population, which resulted to being isolated on a mountain.
enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
