Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
The part of the cell that contains most of its dna is the nucleus
The primary brain vesicles are the forebrain, midbrain and hindbrain. The forebrain is the largest of all the three. Hunger is controlled by the hypothalamus.
<h3>What is the hypothalamus?</h3>
Hypothalamus is a part of the forebrain and is situated below the thalamus region. It controls and regulated the ANS and pituitary activities. It majorly regulates thirst, body temperature, memory, homeostatic functions and hunger.b
It plays a crucial role in controlling the appetite, emotional responses, the release of hormones and physiological cycles.
The prefrontal cortex is the part of the forebrain, the amygdala is the part of the midbrain and the cerebellum is the part of the hindbrain.
Therefore, hunger is controlled by option B. hypothalamus.

Based on genetic analysis of living primates calibrated by the fossil record, it is estimated that apes and Old World monkeys diverged into separate lineages around 25 mya.
<h3>
Miocene apes and modern apes</h3>
- The size of the hands is one way that Miocene primates and modern apes differ.
- The prehistoric primate genus Sivapithecus, which lived between 23.7 and 5.3 million years ago, is regarded to be the orangutan's closest living relative.
- Early in the Miocene, primitive catarrhines, apes, and Old World monkeys were confined to Africa, but by the middle and late Miocene, they had expanded to Eurasia as well.
- Close relatives of living lorises include Nycticeboides and Nycticebus.
- Proconsul africanus, a species of ape, flourished between 23 and 14 million years ago during the Miocene epoch.
- It ate fruit, but probably not as much fruit as an ape does now, and had a brain that was larger than a monkey's.
