Explanation:
the moon does not have an atmosphere so light does not scatter therefore the moon looks black.
Yes but it uses lots of chemistry
Total magnification of objects is 12x.
Dissecting microscopes are microscopes with only one set of lenses so they have less magnification than a compound microscope.
The eyepiece, or ocular lens of microscope, usually has a magnification of 10x. The numbers on magnification knob range from about 0.7 to 3. So, when you want to calculate the total magnification multiply the magnification on the eyepiece with the number on the magnification knob.
The correct answer is upwelling from equatorial to Polar Regions results in bringing oxygen from the epipelagic zone to deeper oceanic zones.
It is a process in which the wind mediated motion of nutrient-rich, dense, and cooler water is moved towards the surface substituting the nutrient depleted and warmer surface water. The epipelagic zone refers to the upper layer of the ocean, which is abundant in oxygen and gets the majority of the sunlight for the procedure of photosynthesis. The upwelling of water from the equatorial to the polar region brings oxygen.
Answer:
Mutation.
Explanation:
Mutation may be defined as the sudden heritable change in the DNA sequence of the organisms. Mutation can results in the change in the genotype and phenotype of the organisms.
Two main types of mutation are spontaneous mutation and induced mutation. Induced mutation occurs intentionally with the help of the mutagens. Spontaneous mutation is the natural mutation that occurs for the no known reason.
Thus, the answer is spontaneous mutation.
