Each of the following statements describes a type of column chromatography. Sort the statements to the type of chromatography th

ey describe. If a statement can describe all of the types, place that statement in the "All" category. (Note that size-exclusion chromatography may also be called gel-filtration or molecular exclusion chromatography.)
Categories: Size-exclusion Chromatography, Affinity Chromatography, Ion-exchange Chromatogrpahy, and All

Statements:
Separate molecules by size.
Separate molecules by charge.
The stationary phase has a covalently bound group to which a protein in the mobile phase can bind.
Uses a mobile phase and a stationary phase to separate proteins.
The stationary phase contains cross-linked polymers with different pore sizes.
Can separate molecules based on protein-lignand binding.
The stationary phase may contain negatively or positively charged groups.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe
Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

<em>BMR calculation =  447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)</em>

<em>In</em><em> </em><em>Harris Benedict Equation, </em><u><em>BMR</em></u><em> is </em><u><em>multiplied</em></u><em> by </em><u><em>activity factor </em></u><em>to determine calories need.</em>

The activity factors in Harris Benedict Equation are:

for no exercise =  1.2

exercise for 1 to 3 days/week or light exercise =  1.375

exercise for 3-5 days/week or moderate exercise  = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

<u>So, calculation for my calorie needs is as following:</u>

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

                        = 974.945 x 1.55

                        = 1511.16 calories

Gnom [1K]

Answer:

The correct answer is Zones of tolerance

Explanation:

All living organisms such as fish,plants and animals  need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
