Answer:
each sense ( eyes ears nose mouth ect.) sends electrical pules through the nerves or "messages" to the brain. which then processes it and turns it into information so that you can understand what you are seeing, hearing, tasting ect
does that help?
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?
These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".
1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU
2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L
3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B
There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart. Our outer layer of skin is epithelial tissue.
