The replica fossil you just created models the actual formation of fossils on Earth. In your replica, what do the clay and the p

The making of replicas of the original fossils, is pretty much the say way, just different materials, in which the fossils originally have been formed and preserved.

When an organism dies, be it a plant or an animal, it gets fossilized only if very quickly after the death it is covered with sediments or mud. The sediments or the mud protect the plant or animal from the outside influences, so once it is kind of in a vacuum, or protective layer if you will, in which parts of the plant or animal that are long-lasting are preserved.

The clay and plaster used for the replica, work in the same way, because they wrap around the fossil tightly and isolate it from outside influences, with the result being different though, as they just make a copy of the fossil.

GarryVolchara [31]

Answer: W = 6.4x10⁻²¹J

Explanation: <u>Work</u> is the energy transferred to or from an object due to the application of a force along a displacement.

The ion Na is gaining energy to move from a lower potential to a higher one.

For this to happen, the work done is calculated as

W=q.\Delta V

in which

W is work in Joules (J)

q is charge in Coulomb (C)

\Delta V is potential difference in Volts (V)

The ion Na has one positive charge. In coulombs, the charge is

q = 1.6x10⁻¹⁹C

The potential difference in Volts is

\Delta V = 40x10⁻³ or 4x10⁻²V

Calculating

W=q.\Delta V

W = 1.6x10⁻¹⁹. 4x10⁻²

W = 6.4 x 10⁻²¹ J

The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.

<h3>Answer:<u><em> The Endosymbiotic theory</em></u></h3>

Explanation:

The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote). This theory explains the origin of eukaryotic cells.

Which one of the following nucleotide pairs would be found in a DNA molecule?
MrRa [10]

Guanine-cytosine is one of the  nucleotide pairs that would be found in a DNA molecule. The other is Adenine- Thiamine.

Explanation:

Pyrine bases – Adenine & Guanine-  pair with pyrimidines bases – Cytosine and Thiamine. Adenine pairs with Thiamine while Cytosine pairs with Guanine.

In RNA, however, while this same principle of base pairing is observed, rather than Thinmaine, RNA has Uracil in its place. Therefore, in RNA, Adenine pairs with Uracil. There is no Thiamine in RNA.
