True of False
True or False: The offspring's chromosomes are picked by the parents
False, The offspring's chromosomes are picked at random
What are Amino Acids?
The 20 different building blocks which make up all proteins in the body.
What do rode cells help us do?
Rod cells help us see when there is not very much light,like at night.
Why are pigment molecules NOT produced in people who do not get tan?
The pigment molecules do not produce in people who do not get tan because the receptor proteins do not match the shape of the molecules.
What chromosome is only found in males?
The Y chromosome
True or False: Mucus can get really thick
True,Mucus could get really thick
What is a Nucleus?
A organelle in cells that contains genes
What do Cone Cells do?
Cone Cells make it possible to see different colors if light.
What has to happen in order for a pigment molecule to be produced in people who get tan?
The signal molecules must fit in the receptor molecules and the receptor molecules must send the signal.
What is a stimulus?
A detectable change in the environment
True or False: We have 4 Sensing Opsin
False, We have 3 Sensing Opsin, A Bluish Sensing Opsin, A Green Sensing Opsin, and A Reddish Opsin.
What is DNA?
The chemical building blocks that make up genes.
What is the nerve behind our eye?
The optic nerve
What is different with the PAH in people who cannot digest Phe?
The Phe is too big and it leaves no room for hydrogen and oxygen.
What is a facial nerve?
A nerve that sends signals from the face to the brain.
True or False: Proteins are not important for genetic code
False, The genetic code determines which amino acids are used into a order to built Proteins.
What are Chromosomes?
Threadlike structures made of DNA molecules which contain the genes.
What happens when light hits our eyes?
When light enters our eyes it travels through our eye ball and lands on millions of special cells in the back of our eye.
What has to happen in order for Phe to be digested and used as a building blocks in our body?
The Phe, Hydrogen, and oxygen need to all fit together to make building blocks.
What are taste buds?
Structures on the tongue that contain the receptor cells for taste.
True or False: Our genes are in our blood
False, In our bodies, genes are found in the nucleus of almost every cell.
What is sexual reproduction?
A method of reproducing where offspring's get half of their genes from each parent at random.
What does the optic nerve do and why is it important?
The signal travels down the optic nerve and into the brain. We know this nerve is important to sight because people with damage to the nerve have blurry vision or are blind.
What is a protein?
A special type of molecule in our bodies that can do things in our cells. A molecule made up of a chain of amino acids that performs tasks for the body.
What are receptor cells?
molecules attached to our cells that can sense a stimulus and start a signal to the brain.
