Answer:
True
Explanation:
In vitro fertilization refers to the laboratory techniques by which a woman's egg is fertilized by injecting a man's sperm in order to develop an embryo outside the body. Subsequently, this embryo can be then implanted into the female uterus to continue with its development. Nowadays, it is possible to decide the stage of development in which the fetus (developed from an embryo) is transferred to the uterus. This situation raises ethical, moral and legal concerns about when a fetus can be regarded as a human being.
We should use wind and solar energy more because those are the two main renewable energy sources, the sun shines a lot so we can use the power from that to power are houses, but at night that would be a problem, so at night you could use water as a renewable energy to power your house at night so you can get light, wind would be good if you live in a windy place like Cheyenne WY.

What is medulla oblongata ?
- Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem.
- The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
- The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration
- The medulla is divided into two main parts: the ventral medulla (the frontal portion) and the dorsal medulla (the rear portion; also known as the tegmentum).
- The ventral medulla contains a pair of triangular structures called pyramids, within which lie the pyramidal tracts.
- The pyramidal tracts are made up of the corticospinal tract (running from the cerebral cortex to the spinal cord) and the corticobulbar tract (running from the motor cortex of the frontal lobe to the cranial nerves in the brainstem)
