Which of the following best describes the highlighted layer on your screen

Option (A)

Explanation:

The image shows the interior of the earth, where the arrow points the core of the earth.

The core is the innermost region of the earth. It is comprised of extremely hot elements such as iron (Fe) and nickel (Ni) whose densities are very high in comparison to the other elements forming the crust and mantle. The density of the earth's core is approximately 13 g/cm³. The temperature and the pressure condition in this region are extremely very high that it is not possible for life to exist.

Thus, the correct answer is option (A).

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
