It interacted with the biosphere and the atmosphere.

poizon [28]3 years ago

Answer: option (1)

Explanation: This experiment clearly represents the interaction between the atmosphere and the biosphere.

        Biosphere refers to the overall life forms on earth and their relationship with other elements that are present in the lithosphere, hydrosphere of geosphere.

Here the leaves where Jake tied plastic bags re considered to be part of biosphere, which he keeps it to react with the atmosphere.

Thus the correct answer is option (1).

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN
Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

  • <em>In any one species, the amount of adenine closely approximates that of thymine.  </em>
  • <em>In any one species, the amount of guanine closely approximates that of cytosine.  </em>
  • <em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA      A            T            G            C </u>

Streptococcus    29.8       31.6        20.5       18.0

Yeast                   31.3        32.9       18.7         17.1

Herring                27.8       27.5       22.2       22.6

Human                30.9       29.4       19.9        19.8

E. Coli                  24.7       23.6        26.0      25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

How does one prevent such a fire from happening​
valentina_108 [34]

Answer:

water

Explanation:

Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material. It simply cannot oxidize any further so it will not “burn”. This smothers the fire. The same thing would happen if you used the ashes that remained after a completely spent fire. Or, as I mentioned before, CO2.

lina2011 [118]

The organelle that provides evidence for this theory is the mitochondria and the chloroplast.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.

In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled  the cells to meet their needs for survival an growth.

The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.

In conclusion the endosymbiotic theory describes  how eukaryotic cells arose from simple prokaryotic cells.
