Answer:

Scientific theories is accepted as a scientific truth, supported by evidence collected by many scientists. The theory of evolution by natural selection is a classic theory. Keeping in mind a Hypothesis is a possible answer to scientific questions.

Explanation:

I majored in Biology

Which structures in the cell are proteins assembled in?
Reil [10]

The nucleolus is where the assembly of the ribosomes begin. Proteins are assembled on ribosomes. Ribosomes produce proteins by following coded instruction of the DNA. Eukaryotic cells contain an internal membrane system known as the endoplasmic reticulum.

Note 1: Balanced forces do not cause alterization motion or movement. This is because of the fact that balanced forces are equal in size and in opposite directions. Consequently, this leads to cancellation and ultimately no movement.The net force for balancing forces is always 0.

Think of it this way: Take your right hand and left hand. Press them together; palm-to palm and five fingers to five fingers. Now apply equal amount of pressure (your force) as you push them in opposite directions (left hand left direction right hand right direction) Does any change in movement occur? 

Note 2: Unbalanced forces are the forces that cause change in movement and motion. When two unbalanced forces are exerted in opposite directions, the overall force (or net force) is the difference between the two forces and the direction is in favor for the larger force. 
Think of it this way. Repeat the exercise I shown you in Note 1, but this time, make apply more force in comparison to the other hand. Your right/left hand's force overpowers the weaker force of the opposite hand. The direction is in favor to your right/left hand (since they obtain the bigger force) as your hands move to the right or left side. This is an example of unbalanced forces at play.

Q22: The two forces on the left and right side are balanced given that their force is equal in size and they are in opposite directions. The two forces northwards and southwards are unbalanced forces since they are not equal in size but are opposite in direction. Recall in note 2 when I given the formula to find the net force for unbalanced forces. Its the difference (subtraction) between the bigger force and smaller force. 5 - 2 = 3. Therefore the net force for question 22 is 3.The direction is in the bigger force's direction, therefore southwards. 


Q24: Is a balanced force. Therefore the net force is 0. I don't think there is technically any direction per say.

What weight of Tris-HCL (MW=121) is required to prepare 2L of a 15% w/v solution?
podryga [215]

Explanation:

Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.

Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.

                 \frac{15 g}{100 ml} \times 2000 ml

                  = 300 g

Thus, we can conclude that weight of Tris-HCL required is 300 g.
