Explanation:
The fetus appears to be sexually indifferent, looking neither like a male or a female. Over the next five weeks, the fetus begins producing hormones that cause its sex organs to grow into either male or female organs. This process is called sexual differentiation.
X- or Y-chromosome sperm have an equal chance of fertilizing an ovum. If Y sperm fuses an ovum, the zygote becomes masculine. When sperm-carrying X combines an ovum, a female zygote develops.
Which body system differentiates a male from a female?The only human organ system that differs significantly between males and females is the reproductive system. Male and female embryonic structures that would eventually form the reproductive system begin similarly, but by birth, the reproductive systems have differentiated.
At fertilization, the embryo's chromosomal sex is determined. Humans need 6 weeks to show the earliest evidence of sex distinction, though.
An ovum has an equal chance of being fertilized by X- or Y-chromosome sperm. The zygote develops into a male when Y sperm combine with an ovum. A female zygote forms when an ovum and sperm-carrying X unite.

Which two types of glia are both glue-like?
Schwann cells and oligodendrocytes
Omicroglia and astrocytes
ependymal cells and microglia
O interneurons and astrocytes
Answer:
There are three types of glial cells in the mature central nervous system: astrocytes, oligodendrocytes, and microglial cells (Figure 1.4A—C). Astrocytes, which are restricted to the brain and spinal cord, have elaborate local processes that give these cells a starlike appearance (hence the prefix “astro”).
The two types of glia that are both glue-like are the Schwann cells and oligodendrocytes that are present in the first option. Glial cells are called "glue-like" cells because they give support to the neuron cells.
What is the importance of the neuron?The neurons are developed in the brain and the spinal cord, and later they get innervated to different organs and regulate their functions because the nervous system works along with the endocrine system. The neuron is either covered with a myelin sheath or uncovered, and in myelinated neurons, the message travels faster than in unmyelinated neurons. Microglia are immune cells, while Schwann cells and oligodendrocytes are found in the peripheral nervous system and the central nervous system, respectively.
Hence, the two types of glia that are both glue-like are the Schwann cells and oligodendrocytes that are present in the first option. Glial cells are called "glue-like" cells because they support the neuron cells.
