Chameleons
by Abi, Denyce, Caden and Alisha
Chameleons
are famous for their quick changing colour abilities. They change temperature of
light and mood. Males become bright to
signal their dominance and turn dark when they feel endangered. Females let males know if they are willing to
mate by changing colour of their skin. They change to bright yellow when they
are angry. Owners of chameleons can learn to read their pet’s mood based on the
colour of their skin. They can change colour because their other layer is
transparent. Transparent means it allows light to pass through so that the
object underneath can be seen. They have
several layers of specialized cells called chromatophores and these cells
change colour. Their tails curl when they are scared, their eyes change to the
same colour of their body. When they are shedding, their skin goes white. They
can go up to 24 inches, and baby chameleons eat flies. Their feet are flexible. There are 100
different types of chameleons.
Differentiated by size, habitat, and colour, their life span is about 8-10
years. Most chameleons live in Japan and
they live in the jungle or the dessert. They are part of the lizard family and
they eat mostly insects and greens. They
are kept as pets. They have a blade on their back to protect themselves from
their predators. Their tongue is 10 feet long. Their brain is the size of a
jellybean. Chameleons are found throughout the deserts, jungle savannas and
forests mostly found on Madagascar. They can be found in the wild. They are
Omnivores, and they are reptiles. Their colours that they can change into are
pink, blue, red, orange, green, black, light blue, yellow, and turquoise. They
mostly eat insects because they are their favourite food. They are often the
target for hungry predators. Their predators are snakes, bird, and mammals. Their main prey are insects, snails, and leaf. To protect their eggs they dig a
hole that is 10-30 cm deep and bury them. Female chameleons have a clutch of
eggs and there are about 20 eggs. Though the eggs can vary from 1 to nearly
100, the eggs take 4-12 months to hatch. Hawks are chameleon’s main predators. Chameleons can change colour in up to 20 seconds
What is RNA
By Stewart, Katelynne
RNA stands for Ribonucleic Acid. RNA is in every cell its role is to act
like a messenger to carry instructions from DNA. It controls the syntheses of
proteins. Although in some viruses RNA rather than DNA carries genetic
information. RNA makes DNA stable. RNA looks with DNA to make protein. The
master blueprint is DNA. Then RNA is the plan carrier. They ether build it in
the cytoplasm or the endoplasmic reticulum. The building materials are amino
acids. The construction workers are:
·
Ribosomes
·
RNA molecules
RNA carries genes. RNA can match any
gene. RNA can be used as a research tool for DNA. RNA works with DNA to become
a gene.
