Check out these photos of the newly discovery species found in the deep waters of the Philippines. The expedition included over two dozen U.S. and Philippine scientists and a group from National Geographic — including underwater photographer Emory Kristof, who teamed with noted underwater explorer Robert Ballard of WHOI in 1985 to find the wreckage of the Titanic.
animal cell are forms of eukaryotic cells which make up many tissues in animals. they actually have small vacuoles. Due to the lack of a rigid cell wall, animal cells can adopt a variety of shapes.
Post your answer the questions below:
1. What are ribosomes?
2. does an animal cell contain a cell wall?
3. Where are where ribosomes constructed?
" ......Sometimes when I reflect back on all the beer I drink I feel ashamed. Then I look into the glass and think about the workers in the brewery and all of their hopes and dreams. If I didn't drink this beer, they might be out of work and their dreams would be shattered. Then I say to myself, "It is better that I drink this beer and let their dreams come true than be selfish and worry about my liver! "

Introduction
What makes food sour? Foods become sour when they receive a high concentration of loose hydrogen atoms. Atoms are tiny particles that make up just about everything we see. They also link to make molecules. Different food have different taste, and every taste has its own amount of hydrogen atoms.
Hypothesis
In this experiment, I will see which foods are most sour.
Materials
The materials I used in the experiment were five different foods, (Lemon juice, vinegar, orange juice, milk, and water), five regular plastic (clear) cups, five bottles, 5 blank food labels, a pen, a cup of dye, and a microscope.
Procedures
First, I emptied each of the five foods into five bottles and labeled each bottle by numbers one to five. Next, I lined up the empty cups right in front of them. Then, I poured five drops of each food from the bottles in each of the empty cups. After that, I identified the cups of what foods I implemented by numbering them matching that to their number bottle they came from. Then, I added a drop of dye to each of the cups. Doing so, each of the foods in the cups changed colors. Next I used a microscope to look into each of the cups too see the hydrogen atoms. Finally I rearranged each cup into in order of highest concentration of loose hydrogen to its lowest.
Data
An illustration of the foods in different numbered cups.
Results
During the dye procedure, I noticed the colors of the foods changed. Looking through the microscope (magnified millions of times), I saw each food’s estimated quantity of hydrogen atoms. Here I found out the most to least sour foods. Most sour was the lemon juice, followed by vinegar, orange juice, milk, and the least was water. The reason why these foods resulted in that order is because of their high concentration. That means the higher amount loose hydrogen atoms with high concentration, the more sour.
Explanation
1. What are acids and bases?
· Acids are basically substances that donate protons (hydrogen ions, H+) to bases. An acid also produces H30+ when dissolved in water. Basis is the substances that accept the protons from the acids. They also produce
2. What is a molecule?
· A molecule is a combination of two or more atoms.
3. Why is pH important in the ocean?
· pH is important in the ocean because aquatic life needs it. The lower the pH (which can be caused by metals) can be more toxic because they are more soluble.
