Most of the fatty acids in cells contain an even number of carbons with 16 to 18 carbon atoms per molecule.
<h3>What are fatty acids?</h3>
Fatty acids are biomolecules which consist of a long non-polar hydrocarbon chain and a polar carboxylic acid head.
Fatty acid are found combined with glycerol molecules to form fats found in animals.
The oxidation of fatty acids produces large amount of energy for the body.
In conclusion. fatty acids are lipid molecules found in living organism that serve as energy stores.

Cons:
It kills animals
It destroys land and trees
It ruins animals homes
Pros
It clears up lane so we can build
Some rare animals need fire to reduce overhanging plants to live ( it’s called a karner blue Caterpillar btw)
And fire is a natural phenomenon that nature has evolved with
Answer:
- They allow for more collisions of molecules (enzymes + substrates)
- They lower the amount of activation energy needed to complete the reaction.
- They speed up chemical reactions to form more products
Explanation:
Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).
Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
Answer : Option D) Fewer people have skin pigmentation lighter than the central peak than people who have pigmentation darker than the central peak.
Explanation : The quantitative variation which is shown for the skin is best explained by option D. Which shows that fewer people have got skin pigmentation which is lighter than the central peak in the graph, compared to the people who have darker pigmentation than the central peak.
Answer:
It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.
