My group (taylor and jonna) and i are doing experiments on snails. Our experiment is to see which they like better peanut butter or cheese. We are going to put cheese on one side then peanut butter on the other. We will do this once a day. For a couple of days seeing if what they choose in the same or if changes. In this proses we will be recoreding our results, this way we can tell which they like better.

1) Fiji water. Total miles = 8,745.7
2) home made roll. Total Co2 = 32,359.09
3) chicken
4) lettuce
5) blueberry
6) fruits snakes

Explain why offspring that result from sexual reproduction are likely to have more diverse characteristics than offspring that result from asexual reproduction
Answer: offspring’s with sexual reproduction are likely to have diverse characteristics, because with sexual reproduction you get have of half your mothers genes and half of your fathers genes. Yet with asexual reproduction the cells is simple copying its self and splitting apart making it identical to the last.

A: for 48 hours of bacteria growing we have seen that the girl s bathroom door knob is the one with the most bateria out of the four.
E: our evidence for this answer is how many bacteria colonies that have grown in it's section and how big they are comparen to the bateria colonies in the other samples
I: in our project we didn't have any inaccuraciesnor scorches of error
O: in our observation we saw that the drinking fountain we swabbed had no bactria growing. We observed that the door knob we saw the bed was the one with the most Bactria, with 4 batercia colonies. That were smooth yellow and whitish bumps. Mr.DiPretes mouth was the second bacteria scorch that had 3 bacteria colonies that were yellow bumps. The smallest bacteria swab we did was the girls bathroom toilet handle that had only 2 bacteria colonies that were yellow smooth bumps.
U: I understand that bacteria grows in multiple places, maybe not in bleache'd areas like the drinking fountain (we suspected that's why it had no bacteria ) and that everywhere we go there's bacteria-even in the hospitals.

Q1) how do cells divid and if a cells splits in half to become two cells how are both able to work?

1:the cells chromosomes duplicates itself, then both of them move apart and go to each and of the cell wall. The cell elongated and it's plasma membrane grows inward, then the cell splits into two. The cell divide ( comely know as sister cells). Those (sister cells) are able to work because the first cells gives them everything need to produce and survive.

Q2) write a brief description of what is happening at each of the seven stages of cell division starting with interphase.

1. interphase: this is the most time consuming part of the cell cycle. The cell is very active while the DNA copies, centrioles divid and proteins are being made.

2. Prophase: during the first stage of mitosis, the nucleus copies the DNA, associated proteins. Each one of the chromosomes has two chromatids, and all chromatids have the same genetic.

3. Pro-metaphase: in this stage the nucleus is no longer recognizable because of the nuclear envelope collapses.

4. Metaphase: when tension is applied by the fibers,they align all the chromosomes in one plane at the center of the cell.

5. Anaphase: the fibers shorten, the kinetochores separate, and the knew cells also called chromatids are pulled apart and begin moving to opposite sides.

6. Telophase: the know cells arrive at the poles and the fibers that have pulled them apart go away for good.

7. Cytokinesis: the fibers that weren't attached to the cell, start to breakdown until there is only a small part of them is still remaining. After the two cells reorganize themselves into a new cytoskeleton for the return of cells.
