Answer the following question given this paragraph: Monotremes reproduce by laying eggs. They have a cloaca instead of a uterus and vagina. The eggs pass through the opening of the cloaca. This form of reproduction is the least risky for the mother. However, eggs are harder to protect than is an embryo or a fetus in a pouch or uterus. Therefore, monotreme offspring may have a lower chance of surviving than the offspring of therian mammals. Q: How do basal mammals like monotreme reproduce? Choices: - cloning - budding - live birth - by laying eggs A:
by laying eggs

Answer the following question given this paragraph: Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons. For example, they provide neurons with nutrients and other materials. Q: Nervous tissue consists of just two basic types of nerve cells: neurons and? Choices: - white blood cells - red blood cells - mammalian cells - glial cells A:
(Answer)
glial cells
