If the body loses a substantial amount of fluids and salts and they are not quickly replaced; for example: by drinking, the body starts to "dry up" or get dehydrated. Severe dehydration can cause death. The usual causes of dehydration are a lot of diarrhoea and vomiting

Heart rate decreased suddenly and then MAP immediately fell because peripheral blood vessels were extensively vasodilated.

Explanation:

A VO2 max test is a clinical test done in a lab and is the ‘golden standard’ for measuring the potential and cardio-respiratory endurance of athletes and bikers.

It measures the oxygen carrying capability through a graded step test which determines the average power output. The maximal oxygen uptake along with cardiorespiratory responses is measured.

As per exercise physiology, the heart rate and cardiac output increases with exercise. When the potential is less, the resistance decreases, heart rate and mean arterial pressure also decrease .

Of all the water on the earth, only about 3% is fresh water. 68% of all the freshwater is frozen as glaciers and is unavailable
AleksAgata [21]

Answer:

The correct answer is statement A.

Explanation:

The procedure of purifying ocean water, that is, the saline water so that it can become suitable for drinking is termed as desalination. Almost 70 percent of the Earth is covered with water and of this only 3 percent is used for drinking purposes. On a huge scale, the process of desalination would require the boiling of water, which would eventually require an enormous amount of energy.  

Reverse osmosis and electro-dialysis are the methods used for desalination. However, these procedures are very costly and cannot be performed on a huge level as it can affect the economy of various countries.

saveliy_v [14]

Answer:

Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos  

Explanation:

La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.

Some chains of carbon atoms bend when the carbon atoms:
svp [43]

Answer:

Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.
