In this post, I’m going to give you some info about the types
and classification of stars
.
Star- a huge ball of gas, a star combines hydrogen atoms to
form helium, this is known as nuclear fusion, and the fusion causes energy to
be released into heat.

Kinds of
Stars
Supergiant- large red (or blue) stars, that do not burn
hydrogen in the core because all their core hydrogen has turned into helium
from nuclear fusion, so they burn it in a region just outside its core, called
a hydrogen-burning shell, when they die, they explode, called a supernova,
these explosions cause black holes to form
Neutron Star- small stars that are only 6-12 miles across, but
their mass is heavier than our Sun, they spin at high speeds, their gravity is powerful,
(in order to escape it, you would have to reach 50% of the speed of light), one
teaspoon of this star weighs 1 billion tons, some of them emit radiation, called pulsars.
Brown Dwarf- a dull, tiny, star that causes nearby stars to wobble

Sharks: the Elite Fish [Part 2]
Let’s continue
with sharks:
Biological
Features [continued]
Ampullae of
Lorenzini are tiny pores on located on the lower jaw and snout. Sharks are also
poisonous (not when they bite). Sharks steal their poison from fish that
contain that poison. But the fish also steal the poison from dinoflagellates algae.
This poison that the sharks eat is ciguatera. Another poison is called
carchatoxin A and B. When ciguatera is consumed it can cause illness and if any
carchatoxin is consumed they can

Sharks are most
commonly known to people as carnivorous man-eating fish. But really they are
mostly harmless to people. Only three species of sharks are considered to be
dangerous to humans, bull sharks, tiger sharks, and great white sharks. Bulls
are considered the most dangerous because of their ability to live in saltwater
and freshwater, increasing the chance of human encounter. Great whites aren't technically the largest shark;
