Question

1. In your body, why do muscle cells and skin cells look and behave differently? (Points : 1) They have different genes. Their genes are being expressed differently. The same genes are being expressed in both types of cells. There is no similarity in their chromosomes. Question 2. 2. Which genes are present in your liver cells? (Points : 1) All your genes are present in your liver cells. Only the genes needed by your liver cells are present in those cells. Half the number of genes is present in your liver cells.

Answer 1

1. Their genes are being expressed differently

2. All your genes are present in your liver cells

I took this in K12 I guarantee these answers

Answer 2

1. Their genes are being expressed differently. This is because, in specialized cells such as the ones you've been given, genes can be 'switched on and off' to express only the cells necessary for the function of that particular cell.
2. All genes are present in your liver cells. Every cell in the body contains exactly the same genes, they are just 'switched on and off' or expressed differently in different sorts of cells.
