A: activators and inhibitors

Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.

guajiro [1.7K]

Answer:

The correct answer is option b. "Alpha eventually replaced by theta".

Explanation:

Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.

alex41 [277]

Answer:

naturalistic observation

Explanation:

The best possible way to study how tigers interact with each other in their habitats would be to use a naturalistic observation. This type of observation focuses on observing the main subject of the study in it's natural environment without interfering in any sort of way. This allows the scientists to observe exactly how the tigers interact when there are no humans around.

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.

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

In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.

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

So, calculation for my calorie needs is as following:

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
