Answer quickly as (50 ) (biology) write a paragraph that describes the experiment conducted by miller and urey. what was their hypothesis? what was their hypothesis? what was their procedure? wht conclusion could they draw from their results?

Stanley Miller and Harold Urey conducted an experiment, simulating the atmosphere as it was before, to explain how compuds would form in those atmospheric conditions (the atmosphere changes over time).

The hypothesis was used as a way of demostrating the origin of life, since in this experiment, organic materials were formed from inorganic materials.

To get the results, they simulated the earth's eraly atmosphere with different gases (the ones found in the atmosphere millions of years ago), water (simulating the ocean) and electrodes (simulating lightnings).

Hope it helped,

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.

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
