A chromatid has something to do with chromosome
Answer:
I think it might be the last one
Answer: (1) Providing an optimized orientation of the substrate.
(2) Decreasing the ∆G in reaction.
(3) Excluding excess water.
Explanation: The active sites of enzymes increase the rate of reaction because they decrease the activation energy of the reaction,and the physical microenvironment provides an optimal orientation of the substrate relative to reactive functional groups while excluding excess solvent,such as water.
Although some active sites may have amino acids that form salt bridges with the amino acids from a substrate,not all do, so this is not a generic strategy of active site microenvironments

Answer:
Nucleolus
Explanation:
The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.
Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.
Organisms that reproduce sexually produce sex cells, or gametes, that carry a single set of chromosomes, the haploid number for the species. In contrast, body, or somatic, cells are the regular cells that form the organism’s tissues and organs. Somatic cells of sexual organisms have the diploid number of chromosomes, one set from each parent. Both cell types undergo mitosis, but only the primary reproductive cells, or gametocytes, also undergo meiosis.
