The hindbrain of the embryo develops into the pons, the medulla oblongata, part of the spinal cord, and what other structure?
Zepler [3.9K]

The hindbrain of the embryo develops into the pons, the medulla oblongata of the spinal cord and the cerebellum.

<h3>What is the cerebellum? </h3>

The cerebellum is a prominent part of the hindbrain and is located just above the brainstem. The cerebellum controls all the voluntary movements of the body and is also responsible for maintaining balance and posture.

The cerebellum is said to make up for 10% of the brain's volume but has more than 50% of the brain's total neurons.

The cerebellum is made up of two parts; a cerebral cortex, a layer made of folded tissue which contains most of the neurons and cerebral nuclei, an inner part which contains the neurons responsible for communication.

Therefore, the hindbrain develops into the pons, medulla oblongata and cerebellum.

the graph predicts the effect that each factor would have on the biodiversity of the mediterranean sea in the next 10 years. how
bixtya [17]

Answer: Exploitation, invasive species

If the government introduces laws prohibiting hunting, it would somewhat reduce the impact of exploitation would have on the biodiversity because hunting is mainly done for the purpose of fun or to derive valuables from animals like skin, horn, ivory, venome for selling them in the international market and making huge profit from them. Introduction of prohibition law on hunting will reduce killing and exploitation of animals for their valuables.

If laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect of invasive species would have on the seas. Invasive species are those living species which are arrive or immegrate to new locations in search of resources. These species compete with native species which results in decline of native species. This will result in disturbance in actual sea biodiversity as this will result in decline in native sea species and may also lead to extinction of native species.
