Answers

Answer 1

Answer:

The rift valley formed when the crust pulled apart.

Explanation:

The Great Rift Valley in Africa formed when the crust pulled apart along a divergent margin.

Rift valley systems are produced within a continent at divergent margins within a plate. The rifting system makes the earth in that region prone to frequent earthquakes as the continents continues pulling apart. It results from the divergence of the Arabian plate and the Somalia/Nubian plate. It is one of the longest rift valley systems on earth.

For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.

What is diffraction?

The phenomenon of waves interacting with particles is known as diffraction. This happens when the aperture's or obstacle's size is of the same order of magnitude as the wave's wavelength.

The wave transmitted through an aperture that has a width smaller than its wavelength expands out completely and behaves like a point source of waves.

The small bending of light as it travels around an object's edge is known as diffraction. The ratio of the wavelength of the light to the opening size determines how much bending occurs.

Therefore, For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.

The karyotype, or chromosomal profile, for humans is shown. A karyotype can be used to investigate genetic disorders. The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle what is a result if preventing spindle fibers from forming

Answers

Answer:

The correct answer is - Mitotic division stops in metaphase and cannot proceed to anaphase.

Explanation:

Spindle fibers do not form during metaphase of cellular division the chromosome would not move in opposite pole and the cell will not move to anaphase.

The chemical colchicine stops the assembling of the microtubules during metaphase of the cell division which prevents the formation of the spindle fibers and the cell did not move to the anaphase from metaphase in mitotic division.

Answer:

If cells do not work together, the organism would die.

Explanation:

Production would likewise be impossible if the Golgi did not generate secretory vesicles, thus organisms would perish quickly if cells did not cooperate.

Because secretion would be impossible, a build-up of substances would ensue, causing other compartments in the cell to malfunction.

Food, germs, and bacteria would not be brought into to the cell to decompose down and cause illness.
