Stable and nonreactive. Using a chemical equation, we can find out the law of conservation of matter, which tells us whether it is an balanced or non balanced equation.
Answer:
Prenatal period.
Explanation:
Two main types of reproduction that exist in living organisms are sexual reproduction and asexual reproduction. The fusion of the male and female gamete leads to the formation of zygote in case of sexual reproduction.
The prenatal period may be defined as the time development required for the fetal to grow in the womb. The prenatal period starts from the conception and remains till the birth of the child. Three main stages of prenatal period are germinal stage, embryonic stage and fetal stage.
Thus, the answer is prenatal period.
Zwitterion
Zwitterion also known as dipolar
ion refers to a substance that has at least one positive and one negative
electrical charge at different locations and the net charge of the entire
molecule is zero. Examples of zwitterions are amino acids.
Answer: A Fixed Action Pattern
Explanation:
A fixed action pattern is an ethological term and off course a natural activity pattern that causes animals to act in a specific behavior pattern distinctive to their species. It is a pattern that is relatively unchangeable within the species and usually ends even when it is interrupted. You can say that, it is innate releasing mechanism or network where sign stimulus exists, once released from neural network; fixed action pattern leads to completion as well.
Answer:
Chemical weathering
Explanation:
Chemical weathering is the process when rain chemicals react with rocks and minerals. In this process, the rocks are weakened. This chemical happening provokes the chemical reaction in the rock or in the mineral.
Chemical weathering is a spontaneous process and it leads to a more stable state for natural materials under a given set of conditions.
