2a. Polymers are very long chains made up of a repeated pattern of monomers

2b. Proteins are made up of amino acids (residues) that bond together to form a polypeptide chain

2c.The information for making a protein is stored in messenger RNA (mRNA)

2d. Ribosomes manufacture protein in cells


3a. The first diagram shows the process of mitosis. The second diagram shows the process of meiosis. Mitosis results in 2 daughter cells whereas meiosis results in 4 daughter cells (as you can see in the diagrams)

3b. Mitosis takes place in somatic cells (any cells in the body that aren't involved in reproduction, whereas meiosis occurs in the sex cells.


4. Meiosis is an essential process in sexually reproducing organisms. It is a process that forms gametes (sex cells) that potentially could result in offspring, all of which would be genetically different.


I can't see the rest of the 5th question but I hope I've helped with the rest. I'm happy to answer any other questions you might have :)

How does the cerebral arterial circle ensure that the brain has a constant supply of blood?
Viktor [21]
Via collateral circulation. This is an alternative route of blood circulation around the brain whenever one pathway is blocked or narrowed. The arterial arrangement of the brain are symmetrically designed in such a way that continuous blood flow the brain is ensured. The cerebral arteries (anterior and posterior) can be interchangeably shared if one of them is restricted. This means that if one artery is blocked/narrowed the other can accommodate the blood flow needed by the brain.
