Google. I also know this, just to make sure you know my answer is right!
</span><em>When the gametes join they form a cell called a zygote. Human sperm and eggs contain 23 chromosomes</em><span><em>. Human zygotes contain </em></span><em>46 chromosomes</em><span><em>. The type of cell division that produces gametes with half the normal chromosome number is called meiosis.</em></span>

Answer;
Neutralization of free radicals
Explanation;
-Peroxisomes are small vesicles found around the cell. They have a single membrane that contains digestive enzymes for breaking down toxic materials in the cell. They differ from lysosomes in the type of enzyme they hold. Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes).
-The oxidative enzymes that break down fatty acids and amino acids, resulting in, among other things, the production of the toxic substance, hydrogen peroxide.
Answer:
Option B. Rna polymerase provides a template for dna is the correct answer.
Explanation:
Messanger RNA is produced in the nucleus using the nucleotide sequence of DNA as a template. The messanger RNA needs nucleotide triphosphates for its production and is catalyzed by the enzyme RNA polymerase. Transcription is the process in which messanger RNA is produced from deoxyribonucleic acid (DNA).
