Answer:
- increasing use of hybrid crops
- altering genes in DNA to create new plants
- developing disease or pest resistant crops
Explanation:
The use of genetic factors to influence the growth of a plant encompasses manipulating the genetic constituent (gene) of such plant.
For example,
- Increasing use of hybrid crops entails mating two pure bred plants based on a gene of interest responsible for a particular trait, to form a hybrid.
- Altering genes in DNA to create new plants is also a genetic factor as it has to with gene modification.
- developing disease or pest resistant crops means that the genetic make up of such plant has been modified to be resistant to pest/disease.
Answer:
Yes it is true because static friction help us to make grip between the foot and the ground surface
Explanation:
Yes, as we know that the friction between two surface is of two types
1) Static friction
2) Kinetic friction
When two surface moves relative to each other then the friction force between two surface is kinetic friction and it always opposes the relative motion of two rough surface
While when one surface has tendency to move with respect to its contact surface but if it can not move on it then in this case it is static friction
So relative motion is not possible in this type of friction
So static friction helps to prevent slipping
It will be a straight horizontal line on the graph
Boiling water has a lot more heat than the oven's air (even though the air has a higher temperature). ... A match has a greater temperature than the iceberg because the average molecule in the match is moving faster than the average molecule in the iceberg
Answer with Explanation:
The direction of the electric field line at any point gives us the direction of the electric force that will act on a positive charge if placed at the point. We know that if we place a charge in an electric field it will experience a force, as we know that force is a vector quantity hence it requires both magnitude and direction for it's complete description. The direction of this electric force that acts on a charge is given by the direction of the electric field in the space. In case the charge is negatively charged electric force will act on it in the direction opposite to the direction of electric field at the point.
