Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.⇔⇔

Mitosis is a type of cell division. organize the images below to show the steps of mitosis.

barxatty [35]

Answer:

The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)

Explanation:

Interphase: Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F)
Prophase: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)
Metaphase: The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area. (FIGURE C)
Anaphase: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H).
Telophase: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)
Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D).
Decondensation of the genetic material of each new cell (FIGURE B).

Which essential fatty acid is rarely found to be deficient as it is typically consumed in abundance in the majority of diets?

galben [10]

Linoleic acid tends to be found in a great amount of foods in the modern diet. This type of fatty acid is found in vegetable oils, nuts, and seeds: with the high amount of items that are eaten from these food groups by the average person, the amount of linoleic acid consumed is typically far more than is required.
