Whether an organism will be genetically male or female is determined by the sperm.
<h3>What is a Sperm?</h3>
- When there is a smaller, male reproductive cell and a bigger, female reproductive cell, this type of sexual reproduction is known as anisogamous sexual reproduction.
- Sperm is the male reproductive cell or gamete.
- Red algae and some fungi create non-motile sperm cells known as spermatia, while animals produce sperm that are mobile and have a tail known as a flagellum.
- The pollen of flowering plants contains non-motile sperm, although other more basal plants, such as ferns and some gymnosperms, have motile sperm.
- Sperm cells are created during the spermatogenesis process, which occurs in the seminiferous tubules of the testes in amniotes (reptiles and mammals).
- They carry either X or Y chromosomes. X chromosome leads to the formation of a girl and Y leads to the formation of a boy.
- Several consecutive sperm cell precursors, beginning with spermatogonia, are produced during this process before they eventually develop into spermatocytes.
Hence, sperms decide the gender of an organism.

An organ or group of specialized cells in the body that produces and secretes a specific substance, such as a hormone
Answer:
The entry of food into the stomach.
Explanation:
Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.
The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.
