Renal failure occurs when the Kidney's fail to function ar required.
What is renal failure?When your kidneys are suddenly unable to filter waste from your blood, you experience acute renal failure. Dangerous levels of wastes may build up when your kidneys lose their filtering capacity, and your blood's chemical composition may become out of balance. Acute kidney failure, which is often referred to as acute renal failure or acute kidney damage, occurs suddenly, typically within a few days. The majority of cases of acute renal failure occur in patients who are already hospitalized, particularly in severely ill patients who require intensive care. Acute renal failure is serious and needs aggressive care. Acute renal failure, however, might be curable.Learn more about the Renal failure with the help of the given link:

Compare phasic and tonic contraction in smooth muscles. what tissues and organs are associated with each?
As for comparison, phasic smooth muscle displays rhythmic contractile activity and is associated with gastrointestinal and urogenital systems. While, tonic smooth muscle is continuously contracted and is associated with the large arteries and veins.
Biology routinely distinguishes between smooth muscle tissues that are "tonic" (producing a slow, sustained isometric contraction) and those that are "phasic" (generating a fast transient isometric contraction).
Smooth muscle is divided into tonic and phasic subtypes, but there are some significant functional differences between these muscle types.
The phasic smooth muscles function as unitary muscles, with action potentials spreading from cell to cell, resulting in coordinated phasic contraction, as seen in gut peristalsis.
While,
Tonic smooth muscle behaves as multiple independent units, or motor units, with graded changes in membrane potential of each unit, i.e., without action potential propagation, resulting in graded changes in force (tone).

Functional groups containing _____ and _____ atoms usually increase the polarity of a molecule.
Answer:
Functional groups containing Oxygen and Nitrogen atoms usually increase the polarity of a molecule.
Explanation:
Oxygen is one of the most important elements in the periodic table. Its atomic number 8 and atomic mass is 16. About 1772, a Swedish scientist named Carl Wilhelm Scheele made the discovery of oxygen. Some compounds like alcohol, water, carboxylic acids, ketones and many others contain oxygen which make them polar. Among all these compounds water is the most important oxygen containing compound.
The scientific name for nitrogen is N, and it is a flavorless and colorless element. The ground beneath our feet contains nitrogen, as does the water that we drink as well as the air we inhale. Atmosphere contains about 78% of Nitrogen. Nitrogen containing compounds are ammonia, nitric acid and many others. Both oxygen and nitrogen make a compound polar.

Two evolutionary processes that may produce a cline in a human allele or trait are?
Two evolutionary processes that may produce a cline in a human allele or trait are gene flow and genetic drift.
What is genetic Drift?
Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it can make previously uncommon alleles far more common and even fixed.
What is gene flow?
The phrase "gene flow" refers to the processes through which genes are transferred from one group to another. Gene flow in anthropology more broadly refers to allelic change brought on by people moving from one place to another.
Hence, in both the cases the allelic frequency is changed and thus with the mutation and natural selection new clines can be formed.

If earth is a "Closed system" how does that shape the outcome of environmental problems
If earth is a closed system then we can't bring anything in or out.
A closed system is one in which only energy can be transported while no matter does, meaning that only energy can enter and exit the system while no matter does. Since it permits energy to enter and exit, the closed system can alternatively be said to be partially open.
An open system is one in which matter and energy are actually being transported or exchanged. Both matter and energy are able to enter and exit the system. In terms of the exchange of stuff, Earth is unquestionably a closed system, but it is an open system for the movement of energy.

A shadow's cross section can be thought of as a backward projection of the item that is obstructing the light in 2-D.
We can't see a shadow when we place the object next to the flashlight and not directly into its path of light because light moves in a straight line, the object could not obstruct the light coming from its source because it was not in the direct path of the light.

Carbon dioxide ________ oxygen unloading and ________ carbon dioxide transport.
a) decreases, improves
b) increases, improves
c) decreases, worsens
d) increases, worsens
Option B: Carbon dioxide increases oxygen unloading and oxygen unloading improves carbon dioxide transport.
During internal respiration or inspiration, we take up oxygen from the environment. While some of the carbon dioxides remain dissolved in the blood plasma, most of this gas continues to flow with the blood. Carbon dioxide here combines with water to form carbonic acid and combines with hemoglobin to form carbaminohemoglobin. Carbonic acid thus dissociates into hydrogen and bicarbonate ions. Bicarbonate ions diffuse out of erythrocytes in exchange for chloride ions, referred to as chloride shift.
Hydrogen ions, dissociated from carbonic acid, bind with hemoglobin. This binding results in decreased affinity for oxygen. Oxygen gets dissociated from RBC and the tissues. Therefore, carbon dioxide increases oxygen unloading. In return, oxygen unloading improves carbon dioxide transport.

To follow Hypertrophy 'Muscle under Stress' is an important component while working out. It is directly proportional to the growth of muscles. These are three mechanisms for muscle growth.
Muscle Stress: In order to grow muscle, it should be kept under a lot of tension using weights and the tension should be more than the body is adapted to. This is a concept of Progressive Overloading your muscle.Muscle Damage: After working out, Muscle Fibres get torn up. This local muscle damage causes a release of inflammatory molecules and immune system cells that activate satellite cells to jump into action.Metabolic Stress: It causes the cells around the muscle to swell. This is from the addition of muscle glycogen which helps muscle and the connective tissue to get swollen up.
