Heads= 46 and Tails=54 Frequency of heads is .46 and frequency of tails is .54.
4. The samples drifted more in the small samples sized than in the large sample siz
Some changes in allelic frequencies that are occurring now may be due to our growing diversity. With many different cultures of people bringing many different traits together in the United States, this may cause changes in allelic frequencies. For example
Week 3 Lab 1. House cat
Kingdom- Animalia (because it is multicellular, eukaryotic, heterotrophic and has no cell walls) Phylum- Chordata (because in some point in life, it has a spinal chord) Class- Mammalia (because it has hair, mammary glands and gives
Week 3 Discussion
Antibiotics are medicines doctors give to us when we are sick. When our illness is caused by bacteria in our bodies, the antibiotics will help to kill and get rid of them. We should only take antibiotics and use things like antibacterial
Week 2 Lab
1. The living animal is my cat, Harry. I now that its alive because it acquires energy form the food I feed it and uses that energy to run around the house and wake us up at 3 A.M. I know that he can reproduce. The properties that characterize
Week 15 Procedure Number of individuals of each genotype randomly selected (before elimination due to mortality) Hb+Hb+: 9 Hb+Hb-: 32 Hb-Hb-: 9 Number of individuals after mortality Hb+Hb+: 6 Hb+Hb-: 29 Hb-Hb-: 0 new allelic and genotypic frequencies base

T, A, C, T, G, G, C These nucleotides come from the nucleic acids in the food we eat. DNA replication occurs in interphase in cells that are about to divide.
4. You can tell by looking at the strand that it is RNA because of the Us fo
Genetically modified crops are crops that are changed in order to better survive and thrive in certain climates. It is used to increase food productivity and yield of crops. This is being done in order to feed the growing number of people on Earth. Althou
Cystic fibrosis is a hereditary disease which affects the entire body, causing progressive disability and sometimes death early in life. The name cystic fibrosis refers to the characteristic scarring and cyst formation in the pancreas. Lung infections oft
C ri du chat syndrome is the result from missing a piece of chromosome 5. The name us based on the cries that come from children affected, which some say sound like a cat's c ry.Some of the symptoms inlcude a high pitched cry, the eyes slanting downward,
Week 11 Lab 1. Most of the cells are not dividing.
2. In the nucleus of a dividing cell, you can clearly see the chromosomes. In the non-dividing cell, the nucleus just looks like a circle. 3. 4. 5. 6. B.=interphase, c.= prophase, d.=metaphase, e.= anapha
T here are advantages and disadvantages to asexual reproduction. T his is when an i ndividual of a species may reproduce on i ts own without another member of the species. T his would mean that there is only one set of DNA being passed on. Sexual reproduc

1. I believe that you are seeing them vibrate because of the water molecules that are bumping into them. Are they moving? It looks like they are moving, though they are only moving a little bit. 2. If a flame was held under the slide I believe
"We are what we eat" is so t rue. The fact that our bodies are made up of mostly oxygen, t hen carbon, hydrogen and nit rogen and this is all that is in all of the foods that we eat is p retty cool. I never thought of it this way, and didn't know that eve

Why so small? I believe that cells are so small because we need many different kinds of cells (like liver cells, skin cells, etc.) and because of the need for diffusion. If we were made up of only one huge cell, there would be no diffusion between cells,
Do genes skip generations? No. The reason why some traits are not expressed is that these would be the traits expressed by recessive alleles. In order for this trait to be expressed in an offspring where neither of the parents expresses it, both parents w
The topic of genetic testing is very touchy. I can honestly say that I have not given that much thought to it until now. After reading the article, I believe that in theory it is a great thing. What I mean by this is that if we have the power to stop some
Week 6 Lab
There is a 50 percent chance of the offspring inheriting either allele.
2. Why? Since there are only two alleles, there is an equal chance of each being inherited. The dominant allele does not have a better chance than the recessive allele.
The courtship display that I found was the one of the Marvelous Spatuletail Hummingbird. The male hummingbird has two feathers attached to his tail by long, thin appendages. While mating, he will move or spin these around very quickly to get the females a
