Radio waves have the longest wavelengths and the least energy.
Answer:
false
Explanation:
This cannot be true because other planets, Earth included orbit the sun witch would have to emit its own gravity
Answer:
Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors can also cause DNA to change. These external agents of genetic change are called mutagens.
There are 384 fluid ounces in 3 gallons. The teacher does not have enough for each student to have 12 fluid ounces.
384÷12=32
4 students would go thirsty.
Even a country in which the birthrate and death rate are equal can experience population growth if it also has immigration.
- In evolutionary time, migration will often quickly converge gene frequencies among populations. Migration is a powerful mechanism for balancing the gene frequencies of subpopulations in a species in the absence of selection. Gene frequencies will eventually equalize if the migration rate is larger than zero.
- Migration refers to the movement of people, groups, or populations. Migration facilitates gene flow, or the transfer of genes from one population to another, in terms of genetics. Migration—or, to be more precise, gene flow—alone will quickly bring the gene frequencies of the two populations together if they initially had distinct gene frequencies and if selection is not at work.
Therefore, immigration is the correct answer.
