Answer:
The correct answer is - 23 (haploid).
Explanation:
Each mature sperm cell is a gamete that is produced by the meiosis type of cell division. Meiosis is the cell cycle that produces four cycle with the half chromosome in number than that of the parent cell. Humans have 46 chromosomes in but as explained the sperm or the gamete have only of that which is 23.
The same goes for ovum which is form by the meiosis second process from oocyte which is basically the egg cell. Both sperm and the ovum fuse to fertilize.
Thus, the correct answer is - 23 (Haploid)
Integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems
Answer:
The correct answer is option C. thymus.
Explanation:
Lymph nodules are small groups of lymphoid tissue present in the loose under the wet epithelial membranes such as the digestive system, urinary bladder, and respiratory system.
The thymus does not contain lymph nodules like other lymphatic organs such as spleen, tonsils and lymph node. However, small lymphocytes known as thymocytes are grouped together in the cortex and epithelial reticular cells can appear like nodules in the medulla.
Thus, the correct answer is option C. thymus.
