Baby Lab

In this lab we had an experiment with a partner we had to compare our features with each other and write who had what and if it was different one person would write big x and little x like so Xx and if the other person depending on the result would of had XX or xx it all depends on what its asking on features and how you look

This is the data table if we had opposites on a feature we had to flip a coin if it was heads it would be the mothers trait so XX for the first feature if it was Xx it would be the fathers trait again it all depends on the person you partner up in my case i partnered up with someone who has the same traits as me so much of our features were the same on the data table

As you see this is what i drew and our baby came out rather ugly i drew the mustache because my partner is hairy so as the baby grows its most likely going to have a lot of facial hair we both have brown hair and eyes but i have curly hair he has flat hair and we both have ovaled shaped heads and not so bushy eyebrows I'm just not good at drawing

Here is my genetics notes

mitosis and meiosis

Meiosis

* Requires two nuclear divisions
*Chromosomes synapse and cross over
*Centromeres survive Anaphase 1
*Halves chromosomes number
*Produces four daughter nuclei
*Produces daughter cells genetically different from parent and each other
*Used only for sexual reproduction

Mitosis

*Requires one nuclear division
*Chromosomes do not synapse nor cross over
*Centromeres dissolve on mitotic anaphase
*Preserve chromosome number
*Produces two daughter nuclei
*Produces daughter cells genetically identical to parent and to each other
*Used for asexual reproduction and growth

Cancer

Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die and new cells take their place. 

When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These extra cells divide without stopping and may form growths called tumors.

Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive one important difference is that cancer cells are less specialized than normal cells. That is , whereas normal cells mature into very distinct cell types with specific functions cancer cells do not. This is one reason that, unlike normal cells, cancer cells continue to divide without stopping 

In addition, cancer cells are able to ignore signals that normally tell cells to stop dividing or that begin a process known as programmed cell death, or apoptosis, which the body uses to get rid of unneeded cells

How the cell wall is and how stages of cancer break it and go all over the body 

toxic lab

poison: The poison i will be talking about is hemlock or known as conium it is a highly toxic flowering plant

Location: Found generally in Europe 

Usage: 100mg of conium or about 8 leaves of the plant is fatal 

Symptoms: Death will come in paralysis your mind is wide awake during the process but your body doesn't not respond to what is happening eventually your respiratory will start to shut down 

Burning this plant can make it difficult to breath and people with asthma should be very cautious of this plant 

Treatment: The only treatment is to be rushed to the hospital for it will first attack the respiratory system and odds are you won't know how to treat that nor have the equipment so the only known treatment is to be rushed to a hospital

Dry Lab

Procedure:
1. we cut out 10 circle liked spinach leaves
2.Then we filled the syringes half way with baking soda
3.Then oxygen was sucked out of the leaves and we waited for them to sink
4.Finally we put them in front of the light and waited for them to float up

Research:
Photosynthesis is a procedure used by plants and other organisms to covert the light energy it gets and into chemical energy that can later be released to fuel the organism. in the lab i saw photosynthesis accrue  during the lab when we have put the leafs in front of the light the spinach leafs had floated to the top of the syringe because of photosynthesis because when the light hit the syringe the leaf would react to the heat produced from the light and rise up but it did take a while for it to rise

Materials
1. syringe
2.spinach leaf
3 Baking soda
4. Red and Blue plastic cup
5. bright light
6. hole puncher or material that can make circled leafs

Graph:

When we put the leafs in the syringe surrounded by the red film and put it in front of the light photosynthesis occurred faster than baking soda and the blue film we originally thought adding a lot of baking soda would increase the thought of photosynthesis but it ended up being the 2nd best at photosynthesis and the reason the blue film was the lowest was because the film its self is darker and it is harder for the light to penetrate thought the dark blue film and its a lot easier for it to go through the red film

Reflection: The thing i would do differently is add a more intense light to see an increase in time for photosynthesis to happen it took around almost ten minutes for the first leaf to rise up next time i attempt this lab i am aiming for a shorter time and faster rise of leafs

Photosynthesis Dry Lab

In this “dry lab” you will be working backwards from what you would normally do in a lab situation. In this case, you will be given a set of observations that were made in a lab and you will be asked to reconstruct the procedure that could have generated this data. You will also be given a set of facts that you will use to explain this set of observations in the analysis and conclusions section of your lab write-up. As you create the procedure for this lab, please remember all the rules that you have been learning about good experimental design.

Your lab report begins below. Fill in the missing sections of the lab report using the observations and facts given. You may assume that you have access to as many test tubes, snails, Elodea plants, light sources, dark places, and as much pond water and BTB as you need.

My Most Awesomest Photosynthesis Lab Report

by

Question(s):

Background Research Facts About Photosynthesis and Respiration:

• Carbon dioxide in water produces carbonic acid.
• Bromothymol Blue (BTB) is a blue-green liquid which changes to a yellow color in acid and back to blue-green when returned to a neutral pH.
• Carbon dioxide plus water yields sugar and oxygen when chlorophyll and sunlight are present.
• Animals respire.
• Green plants photosynthesize in the light and respire all the time.
• Sugar plus oxygen yields carbon dioxide plus water and energy.

Materials:

1. water

2. blue Btb

3.beaker

4.snail

5.plant 

Procedure:

1. put room temperature in beaker
2. put four drops of btw in beaker with water 
3. stir the beaker till btb is mixed with the water
4. put a snail in beaker that has water and blue btw
5. then follow step 1,2,3 with a new beaker
6. put plant in the new beaker 

Results/Evidence:

1. Water plus bromothymol blue is blue-green.
2. Water plus bromothymol blue plus an aquarium snail turns yellow.
3. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light.
4. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours.

Analysis of Results (use your Research Facts to explain each result):

1. Water plus bromothymol blue is blue-green because... bromothymol (btb) is a blue looking liquid which later turns into a yellowish color in acid and back to blue- green when returned to a neutral ph

2. Water plus bromothymol blue plus an aquarium snail turns yellow because... when you put a snail in water then the acid of the snail and the carbon dioxide react with btb which changes to yellow

3. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light because... when you put the plant elodea in some water it turns to blue-green

4. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours...
