The rigth answer is D.
The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).
Answer:
What becomes more will be less
Answer:
They would be 60,000 miles long. Which is enough to go around the world twice.
Explanation:
Yes, evolution through selection procedure better organism in an absolute sense and yes, we are climbing the Scala nature
Explanation:
The process of natural selection influences the production of beneficial organism in a population. in this process organism with great evolutionary adaptation are produced. the organism which has better fitness in evolution has a great contribution in a gene pool.
Diversifying, directional, stabilizing, sexual etc are various ways in which the process of natural selection affects the variation and quality of traits in the population.
These changes can<span> be caused by environmental factors such as ultraviolet radiation from the sun, or</span>can<span> occur if an error is made as </span>DNA<span> copies itself during cell division. Acquired </span>mutations<span> in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.</span>
