Answer:

D. at the bottom of the lake buried by a landslide.

Explanation:

Hello,

Fossils are known as the ancient remains of the animals or plants that lived on earth so long ago. They are produced when different tissues of plants and animals parts are decomposed by microorganisms present in the soil, in addition to hard remains of bones, wood, shells and exoskeletons that are still accumulated. Such remains are usually buried under several layers of soil and debris, thus, they get compacted and consequently transformed into rocks.

Now, the most suitable environment for the preservation of fossil remains is at the bottom of a lake buried by a landslide, since the several layers get deposited over the fossil remains, taking care of them and subsequently promoting fossil preservation.

Best regards.

How long would it take a current of 10A to deposit 6.36g of copper during the electrolysis of copper (ll) tetraoxosulphate VI so
zhuklara [117]

It take 0.54 hours to deposit 6.36g of copper

<h3>Further explanation</h3>

Faraday's Law I

"The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis

W = e.i.t / 96500

\tt \large {\boxed {\bold {W \: = \: \dfrac {e \times  i \: x \: t} {96500}}}}

e = equivalent = Ar / valence

i = current, A

t = time, s

W=6.36 g

e = 63.5 : 2 =31.75

i = 10 A

\tt t=\dfrac{W\times 96500}{e.i}\\\\t=\dfrac{6.36\times 96500}{31.75\times 10 }\\\\t=1933.04~s\approx 0.54~hours

In what type of reaction or process does heat flow into the system
SCORPION-xisa [38]

Answer:  The correct answer is:  " endothermic . "

______________________________________

<u>Note</u>:  Heat flows <u> into </u>  [heat <u> may be </u> absorbed within] an "<u>endothermic</u>" reaction or system

          To the contrary, heat flows <u> </u><u>out </u>  [heat  <u> may </u><em> </em>exit from or <u> may be </u> released from] an "<u>exothermic</u>" reaction or process.

<u>Hint</u>:  Think of the "prefixes" of:  "<u>endo</u>thermic"  and "<u>exo</u>thermic" :

_____________________________________

  1)  endo- = "within" (as in "endothermic" —heat tends to be absorbed/"within"/"released within"/released within"/into" ;

  2) exo-   = " outwards"/"exit" (as in "exothermic") —heat tends to '"exit"/leave/escape from/"be released out of/form".

_____________________________________

Hope this is helpful to you!

Best wishes to you in your academic pursuits

     —and within the "Brainly" community"!

The electrical wires in your home use what type of circuits?
Helga [31]
The house wiring should be done parallel because, in parallel connection there will be more advantages than a series connection.

Let a house is wired in series and it contains a fan, tube light, TV, refrigerator. All the devices are connected in series. Now, due to some disturbance the fan speed working or it burned. Then since the connection was a series, due to one appliance failure causes the whole circuit to fail. If it is burned that means it making an open circiut. Then there will be no current flow in the circuit.

Now if it was a parallel connection as we know already, the parallel connection is nothing but individual appliances connected to the same line by tappings. That means there's no dependency of one appliance on another. So if an appliance fail or burns it doesn't effects the remaining appliances. And there will be uninterrupted supply to the healthy appliances can be achieved.

That’s why we use parallel for house wiring
