Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
Digestive System Organs And Its Functions
______________________________________________________________
- Mouth - digestion starts when taking a bite of any food, by chewing it allows the food to be broken down causing digestion to be easier.
______________________________________________________________
- Esophagus - is located in your throat near the trachea, it reiceve the food from your mouth when you swallow
______________________________________________________________
- Stomach - holds the food while its being mixed with enzymes that allows the food process to be broken down in a usable form.
______________________________________________________________
- Small Intestine - its made of three segements; the duodenum, jejunum, and ileum. It <span>that breaks down food using enzymes released by the pancreas and bile from the liver.
</span>______________________________________________________________
- Pancrease - first segment of the small intestion that allows enzymes to break down proteins, fats and carbohydrates. Also produces isulin.
______________________________________________________________
- Liver - is to procees nutrients, to digest fats, to <span>detoxifies potentially harmful chemicals
</span>______________________________________________________________
- gallonbladder - stores <span>concentrates bile, and then releases it into the duodenum
</span>______________________________________________________________
- Collon- is <span>for processing waste so that emptying the bowels is easy and convenient.
</span>______________________________________________________________
- Rectum - <span> to receive stool from the colon,
______________________________________________________________ - Anus - </span><span>stops stool from coming out when it is not supposed to.

sorry for the lack of explanation. this too much work for me</span>
Answer:
The breating rate is the dependent variable because it can be affected by varying weights.
Explanation:
In an experiment, the dependent variable is the variable that is not manipulated but is influenced by the changes that are done to the independent variable. In other words, it depends on the independent variable.
So in this case, the breathing rate is the dependent variable and the weight differences is the independent variable because the change in weight is what is changed to see if it will affect the breathing rate, which is the dependent variable.
