6 0

Easy answer: its too hot.

The deepest man made hole is Kola Superdeep Borehole. That was a Russian experiment to see how deep you could drill into earths crust, reaching down 12,262 meters. At that depth the temperature reached 180 °C. The scientists estimated that a 15,000 meters depth the temperature would reach 300 °C, and at that temperature the drill would cease to work and the project was stopped.

mario62 [17]

Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.

DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, _______ is mad
lions [1.4K]

DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, proteins are made by translating mRNA.

<h3>What is DNA and what is its function?</h3>

DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.

DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).
