Answer:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units.
Explanation:
The answer is “C”. Natural selection is about ones traits being better than another’s which allow it to survive in the wilds longer.
D because kg is mass and cubic cm is volume which Density = Mass / Volume
It's the mitochondria, the "powerhouse of the cell".
Answer:
Ribosomes are present attached to the rough ER:
1. To easily make proteins that are required inside and outside of a cell.
2. To take up amino acids easily.
3. To make it easier for the mRNA to travel from the nucleus to the ribosomes.
Explanation:
Ribosomes are involved in the synthesis of proteins. The rough endoplasmic reticulum is attached to the nuclear envelope. Hence, this provides an easy pathway for molecules to travel between the nucleus, rough ER and endoplasmic reticulum.
During the formation of a protein, mRNA is formed and the mRNA travels to the ribosomes through the rough ER. The location of the ribosomes makes it easy to take mRNA from the nucleus and amino acids from the cytoplasm and make proteins. When a protein is made, it can be used inside the cell or can be transported to the Golgi apparatus etc.
