<u> Allele frequencies to change from one generation to the next.-</u>
<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>
- Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
- When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.
Why do allele frequencies change from one generation to the next?
Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.
No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.
What are 5 factors that cause changes in allele frequency?
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
- These include natural selection, gene flow, genetic drift, and mutation.

Answer:
(B)False
Explanation:
active transport is the movment from a region of higher to a region o lower concentration
I believe you are right;
The Calvin Cycle occurs in the chloroplast during photosynthesis
The Krebs cycle occurs during cellular respiration in the mitochondria
Light energy is only needed for photosynthesis in the chloroplast
Hydrogen ions are present in both cycles<span />
Answer:
What little is known is that the Earth's magnetic field creates the so-called A "magnetic shield" that protects against other dangerous forms of radiation, namely cosmic rays and solar wind.
While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.
In addition to the growing problems of Earth's environment, there are other conclusions that can be drawn from the weakening of its magnetic field:
1) C-14 carbon dating should be reconsidered;
2) There is an age restriction for both the Earth's magnetic field and the Earth itself.
Explanation:
Electromagnetism is a branch of classical physics that investigates the causes and interconnections of electrical and magnetic phenomena, explains the light phenomena and laws of optics, and all other types of electromagnetic waves.
The development of electromagnetism began in the early 19th century with the experiments of HC Ørsted and M. Faraday. reached in A. Einstein's special theory of relativity.
On a global scale, two important force fields connect to planet Earth: Earth's gravitational field and Earth's magnetic field. The gravitational field draws us towards the earth, keeping us from flying into space at Earth's rotation. It also prevents the atmosphere from leaving our planet. The atmosphere, on the other hand, provides protection against some types of cosmic healing. For example, ozone in the atmosphere protects from ultraviolet rays, a deadly form of radiation.
It is necessary to calibrate the ocular micrometer with each objective because the magnification of each objective lens are different. The numerical value is specific and only holds for a specific objective ocular lens. So, they should be checked accordingly.
