Protein is a cell's main source of energy.
B. bone.
C. blood.
D. fat tissue.
Answer:
The correct answer is option A. "skin".
Explanation:
Hair and nails are derived from cells of the skin. The cells of the skin have keratin, a protein that creates a protective barrier against the environmental factors that could affect them. The hair and nails are modifications of skin cells, that have keratin but with additional features. The hair is made of 95% keratin and is formed of three components: medulla, cuticle and cortex. The nail cells are made from keratin as well, forming a horn-like structure that is replaced by skin cells constantly.
Living organisms use 20 standard amino acids to make proteins, as coded by DNA. However, there are additional ones that are modified post-translation into proteins, raising the actual total number of amino acids found in a living organism.
In living organisms, there are 20 standard amino acids that are used to make proteins. These comprise the basic set of amino acids encoded by the genetic code. However, there are additional amino acids, not directly coded for in DNA, that are modified after being translated into proteins, like hydroxyproline and selenocysteine, making the actual total number of amino acids in a living organism somewhat higher than 20.

Since we've been using petroleum in vast amounts organizations such as OPEC have appeared which restricts the U.S which ensued our country into suing; if this lawsuit passes then we will possibly be taking more petroleum than ever before due to it's demand such as it's needed for machinery and vehicles and etc. Most petroleum are from middle eastern countries, so our dependency will run rampant which will make us adhere to any of their policies pertaining to this fossil fuel in the near future.

The downfall of a tragic character is the result of "a tragic flaw".
The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.

sink in corn oil and float to the top of water
float in corn oil and in water
sink in corn oil and float in the middle of water
Answer:
Corn oil has a density of 0.7 g/cm3. Water has a density of 1.0 g/cm3. A piece of plastic with a density of 0.9 g/cm3 will sink in corn oil and float to the top of the water.
Explanation:
Density is a unit that let us know the quantity of mass that a substance has per unit of volume. In a solution, the component with lower density will float, and be on the surface.
If we compare the densities of corn oil and a piece of plastic, the plastic will sink because its density ( 0.9 g/cm³ )is higher than the one of the corn oil (0.7 g/cm³).
In the case of the water, the plastic will float to the top because its density ( 0.9 g/cm³) is lower than the one of water (1.0 g/cm³).
