An error occurs during cell reproduction, and a particular cell is lacking ribosomes. Which cellular process will not be able to occur in the cell?
A student obtained a solid product in a laboratory synthesis.To verify the identity of the solid,she measured its melting point and found that the material melted over a 12^degree C range.After it had cooled,she measured the melting point of the same sample again and found that this time the solid had a sharp melting point at the temperaturr that is characteristic of the desired product.Why eere the two melting points different?What was responsible for the change in the melting point?
1.Explain why ice,which is a crystalline solid,has a melting temperature of 0^degree C.whereas butter,which is an amorphous solid,softens over a range of temperatures.
2.Why is the arrangement of the constituent atoms or molecules more important in determining the properties of a solid than a liquid or a gas?

You are going to make an employee management system. In this lab, you have to create
an Employee class only. Employee class fields are: Employee Name, Employee ID, and Employee Gender. The member functions include the getters and setters for all the member variables and display () function to display the data. In the main function, first create two Employee objects and allow the user to enter data in these objects. Secondly, display the data from these objects.
Show that the equation 𝑣=√t/μ
does give the
appropriate units for velocity.
A car moving along straight road at 30m/s slows uniformly to a speed of 10m/s in a time of 5.0s. Determine
