Answer:
The correct answer will be option-Selective survival and reproduction is a requirement of evolution by natural selection.
Explanation:
Evolution is a slow process of change in the heritable features of species over a successive generation of time.
The process of evolution takes place during a long period of time only when the advantageous mutations are passed on to the generations and become established.
The mechanism of this process is natural selection which increases the reproductive rate as well as the survival rate of the species.
Thus, the selected option is the correct answer.
Answer:
This conversion of one form of energy to another is called energy transformation.
Explanation:
Eye is one of the most important sensory organ of our body that helps in the perception of light.
When we see a light at that time light energy is converted into neural messages and then carried to the brain by ophthalmic nerve for processing.
Here the law of conservation of energy is maintained which states that energy cannot be created nor destroyed, energy can only be transformed.
The answer is lag. The number of bacterial cells doubles at a constant, exponential rate during log phase, while growth rate and death rate are the same during stationary phase. The fourth phase is the death phase, when the rate of cell death is faster than the population growth.
The pectoral muscles are found on the anterior chest wall (thoracic wall) of a pig. Three pectoral muscles are:
1. Pectoralis major- the most superficial muscle in this region.
2. Pectoralis minor- the muscle that is below the pectoralis major
3. Serratus anterior- the muscle that is adjacent to the chest wall
