Researchers have found that main centers of the brain's reward circuit are located along the MFB. the VTA and the nucleus accumbens are the two major centers in this circuit.

Explanation:
<h2>In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.</h2>
<span>The
mitochondria are famously known as the powerhouse of the cell since it is the
one that gives the cells energy that is also used by the human being. This energy conversion is called oxidative
phosphorylation. Mitochondria are found in eukaryotic cells, including
humans. These organelles also had its
own genome, or what we called as DNA which is known as mitochondrial DNA, or
mtDNA which is present in the mitochondrial matrix. The role of mtDNA or mitochondrial DNA is to
convert the energy from food into any other forms that it thinks the cell can
use. It is containing 37 genes which are
all necessary for a normal mitochondrial function.</span>
The similarities between sharks and dolphins are : Analogous
<h3>What are analogous structures ?</h3>
Analogous structures are similar structures present in different species that do not share the same/common ancestor.
The similarities between sharks and dolphins are streamlined bodies and the possession of fins and they are analogous structures because they evolved differently for sharks and dolphins as they do not share a common ancestor.
Hence we can conclude that The similarities between sharks and dolphins are : Analogous

At the end of the 19th century,
The French biologist Alexandre Yersin discovered the germ Yersina pestis.
Yersina pestis spread the "Black Death". With the help of modern
microbiologist's study with a namatode (C. elegans), genes that may play a part
in the transmission of plague have been identified. Along with this knowledge,
the microbiologists understood that the bacillus travelled from person to
person through the air and from bites from infected fleas and rats. According
to biologist Paul-Louis Simond, the bacteria blocks the digestive tracts of the
fleas and stimulates them to bite and people repeatedly, injecting and
spreading the bacteria. The bacteria hitchhike in immune cells in lymph nodes
and the infection begins and transmits to others. Antibiotics are then chosen to fight the bacteria.
