Examples of Nucleic Acids. Nucleic acids, best-known as DNA and RNA, are often termed "the building blocks of life." These building blocks are found in the nuclei of cells and help proteins to be built, help cells to replicate, govern heredity and the cell's chemical processes.
Answer:
Altruism is a form of prosocial behavior, which is used to describe a person who is helping someone with no intention of having any internal or external reward in return. Some psychologists suggest that altruism is a key motivation for prosocial behavior.
The answer is lethal dose 50 or LD50.
LD50 is a measure of a lethal dose of a substance that can be toxin, radioactive or pathogenic. The value of LD50 for that substance is the dose required to kill half of the animal population. For example, in a population of 100 rats, the dose necessary to kill 50 of them is the lethal dose.
The correct answer is: B) 6 CO2 + 6 H2O ? C6H12O6 + 6 O2
Photosynthesis is a process of converting light energy to chemical energy in the form of sugars (carbohydrates). It is performed by plants, some algae and bacteria.
In the reaction of photosynthesis, sun energy combined with carbon dioxide (CO2) and water (H2O), to form glucose (C6H12O6) and oxygen (O2). Photosynthesis consists of two stages: the light-dependent reactions (in thylakoid membrane) where ATP is formed and the Calvin cycle (in stroma) where ATP is used.
