Answer:

Different genes are expressed in different cells

Explanation:

The instruction is provided to the cell by the genetic material in the form of genes. Genes are the physical segment present on the DNA which can code for a specific protein.

The genes are present in the cells in the condensed form called chromosome which is present in all the cells of the body.

Although all the cells contain the same type of chromosomes or genes but they differentiate to perform different functions.

The differentiation process involves the expression of different genes in different cells as a result of which different proteins are formed in different cells and they perform different functions.

Michael and Andrew are pushing a desk across the room. To be funny, Michael decides to push against Andrew instead of with him.
lions [1.4K]

Answer:

towards Andrew

Explanation:

The direction in which the desk will move would be towards Andrew.

This is a simple case of resultant force. If both Michael and Andrew had pushed the desk together across the classroom, the resultant force would have been the addition of their individual's applied forces - neglecting any other extraneous forces. However, since they decided to push against each other, the resultant force would the subtraction of their individual forces and the desk will move towards the person with who applied the lower forces out of the two.

<em>Since Michael applied force was 30 N and that of Andrew was 28 N, the resultant force would therefore be 2 N in the direction of Andrew. In other words, </em><em>the desk would move towards Andrew.</em>
