<u>Answer:</u>
The<u> Lead </u>toxicity can result in slow growth and iron-deficiency anemia, and can damage the brain and central nervous system.
<u>Explanation:</u>
Lead poisoning is a form of metal poisoning in the body which is triggered by lead. The most prone of these is the brain. Signs can be abdominal pain, indigestion, fatigue, irritability, problems with memory, failure to have children and numbness in the hands and feet.
It triggers nearly 10 per cent of quite unknown cause's intellectual disability and can lead to behavioral problems. A few of the consequences are irreversible. In extreme cases there may be coma, anemia, seizures or death.
1. A genome is the complete set of an individuals DNA
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 :)
