Our star—the Sun—is a bubbling, boiling ball of fire. See Picture 1 to the right. It constantly belches out great clouds of hot gas. This gas is all charged up with electricity, too. This stuff travels at astounding speeds, some of it right toward Earth! This means that Earth’s weather happens inside the Sun’s weather!
Thank goodness Earth’s magnetic field (see Picture 2) and atmosphere protect us from most of this blast. Otherwise, the Sun’s weather would be OUR weather. Yikes!
However, we are still affected by the Sun’s atmosphere and its violent activities. We call this part of our weather “space weather,” because it comes to us through space from the Sun.
Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
Explanation:
Factors b,d,e,g are favorable to fossil formation and preservation.
<span>Hard bodies are more easily preserved; rivers and oceans deposit muds that keep bodies intact for long times after death; large population and long existence provide more opportunity for fossils to form; and a low oxygen content impedes decay and inhibits predators. </span>
<span>Factors a,c,f,h are unfavorable to fossil formation and preservation. </span>
<span>Thus, Organism E with 4 positive factors is number 1 -- has the top chance of forming a fossil. </span>
<span>Organism D with 4 negative factors would be number 5 -- has very little chance of forming fossils. </span>
<span>Of the other 3, all have soft bodies, so are "disadvantaged" compared to E...but </span>
<span>Organism A has no OTHER disadvantages, so is probably number 2 (second best fossil chance). </span>
<span>Organism C has ALMOST everything going against it -- despite its large population and long existence, it has no other positive factors -- so I'd put it at number 4 (second worst). </span>
<span>To summarize, my rankings are </span>
<span>1. E, 2. A, 3. B, 4. C, 5. D</span>
Eukaryotes (IPA: [juːˈkæɹɪɒt]) are organisms whose cells are
organized into complex structures by internal membranes and a
cytoskeleton. The most characteristic membrane bound structure is the
nucleus. This feature gives them their name, (also spelled "eucaryote,")
which comes from the Greek ευ, meaning good/true, and κάρυον, meaning
nut, referring to the nucleus. Animals, plants, fungi, and protists are eukaryotes.
