kvasek [131]3 years ago

The evidence that supports the conservation law is that Carbon dioxide becomes glucose and oxygen during photosynthesis. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed. For example in photosynthesis the reactants are 6 carbon dioxide, 6 water and sunlight which adds to the mass of products which is; 1 glucose and 6 oxygen.

The normal range of arterial blood ph is:_____
LekaFEV [45]

The correct answer is [c] 7.35-7.45

The normal range of pH of arterial blood pH 7.35-7.45.

<h3>What do you mean by arterial blood?</h3>

Three different tests—pH, Pco2, and Po2—are typically taken in conjunction to assess the patient's acid-base state, ventilation, and arterial oxygenation. This group of measurements is referred to as arterial blood gases (ABGs). The most significant respiratory gases are oxygen (O2) and carbon dioxide (CO2), and the partial pressures of these gases in arterial blood indicate how well gas exchange is functioning generally.

Age and altitude have an impact on Pao2. Paco2 by height. As a result, Pao2 needs to be determined specifically for each patient, and both results need to be compared to the neighborhood's norms. Because hydrogen is not a gas in blood, it does not impose a partial pressure. However, every arterial blood gas determination includes pH, which assesses hydrogen ion activity. Blood pH should fall between 7.35 and 7.45.

The ABGs may include certain calculated or derived variables. The most helpful of these is the bicarbonate concentration, which may be determined from the pH and Pco2. Others are not necessary and could be confusing, such as base excess and base deficiency.

Describe how the location of the center of gravity of
Rina8888 [55]

Explanation:

The effect of the position of the CG on the load imposed on an aircraft's wing in flight is significant to climb and cruising performance. ... This requires a higher AOA (Angle of Attack) of the wing, which results in more drag and, in turn, produces a higher stalling speed.

Maria is a 121-lb endurance athlete who is planning to employ carbohydrate loading before her next race. Which strategy correctl
xz_007 [3.2K]

Answer:

Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.

Explanation:

Carbohydrate loading is for constant  supply of  constant energy as ATPs for the skeletal muscles cells during high intense activity, to reduce fatigue, and increase performance for upmost performance.

The   main objective  is to  sustaining muscle  contraction during intense  exercise  

The practice   involved increase in   intake of high carbohydrate meals  a   few weeks before the commencement of the sporting activities. This is stored  as  muscle glycogen, as well as in the  liver glycogen and brain.  

The physiology involved  the conversion of  muscle glycogen  to glucose -6-phopahate in the liver, and its entry  into Glycolysis, and Krebs’s cycle to generate ATPs.

The use of muscle glycogen during strenuous exercise reduces   blood glucose uptake, and ensured that its level is at a relatively constant value for the body homeostatic conditions, without exogenous carbohydrate intake
