Answer:

The correct answer is option D, Receptor protein

Explanation:

A Receptor protein is found on the outer side of the cell and they provide receptor sites where a foreign chemical messenger can get associated and perform its function. As the name also suggest , “receptor” which receives chemical signals from outside a cell. Some common example of receptor proteins are ion channels such as ligand gated ion channels , enzymes etc.

Thus, it can be a receptor protein which has the ability to bind to hormones or other chemical messengers.

What volume of 15.6M NH4OH is needed to make 500.0 mL of 3.00M solution? a) 0.962 L b) 0.00962 L c) 0.026 L d) 0.0962 L

topjm [15]

Answer:

d) 0.0962 L

Explanation:

The problem describes a dilution process, meaning that we can solve it by using the following equation:

C₁V₁=C₂V₂

Where subscript 1 stands for the volume and concentration of the concentrated solution, and 2 for those of the diluted solution. That means that in this case:

C₁ = 15.6 M

V₁ = ?

C₂ = 3.00 M

V₂ = 500 mL

We input the data:

15.6 M * V₁ = 3.00 M * 500 mL

And solve for V₁:

V₁ = 96.2 mL

Finally we convert 96.2 mL to L:

96.2 mL / 1000 = 0.0962 L

The answer is thus option d).

Two forces act in opposite directions on a object, and how will this affect the object’s motion?

kiruha [24]

it depends on the force of each object if there is greater force moving left than right the object is moved to the left if the forces are equal the object will not move and of the force on the right is greater than thta on the left the object therefore will move right.
