Your nervous system interacts with every other systems in your body. Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes. Your digestive and excretory systems work with the nervous system in both conscious and unconscious ways.
B. Both processes form woven bone.
Explanation:
Bone growth and development is mainly characterized by bone ossification processes taking place through the two main osteogenic pathways – intramembranous and endochondral ossification.
The woven bones are the primary immature bones formed by both these ossification processes from the bone cells (osteoclasts, osteocytes, osteoblast) and calcified bone matrix. These woven cells later developed into the mature secondary bones or the lamellar bones – spongy (cancellous) or compact (dense cortical) bones.
Intramembranous ossification takes place mesenchymal sheets of connective tissues and produces soft spongy bones.
Endochondral ossification results in replacement of hyaline cartilage to form the long bones.

Since chromosomes in the nucleus exist in pairs, human body cell contains 46 chromosomes arranged in 23 pairs.
Gametes are haploid, so their nucleus only contains a single set of 23 unpaired chromosomes.
Answer:
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
OR
In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.
