The blue triangles mean a cold front
Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!
Mitosis and meiosis
The statement is true. While mitosis's main function is to repair and grow, meiosis fulfills its function in reproduction, forming the egg and the sperm, the cells involved in the fecundation to form a new individual.
Answer: Contour ploughing
Explanation: The soil conservation can be defined as the techniques that are opted to conserve soil. It is necessary for the soil to be conserved as it is necessary for the growth of plants.
There are various methods that can be used to conserve soil. Contour ploughing is one of them. In this method furrows are made that move left to right to maintain a constant altitude.
This technique reduces the runoff which helps in the soil conservation.
