The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron  are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />

Oksana_A [137]

Answer:

D. Changes in the environment changed each morph's ability to evade predation in different ways.

Explanation:

The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.

When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number  as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.

Therefore, option D is best option.

Hope it help!

What is different about normal cell division and cancer cell division?
Alex17521 [72]

Your body constantly produces new cells. Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells.
