The remains are called fossils. Fossils are remnants of animals, plants, or microorganisms that have been solidified in the process of fossilization, where the organism is surrounded by sediment, minerals, and other solid objects which are compressed and heated around the organism over time. This forms a solid mass with the preserved organism inside, other known as a fossil.

gogolik [260]

Answer:

No, I don't reckon that water is alive. I don't think that it is "dead" either. It simply just... exists. However, it DOES hold life within it. But the water itself is not alive, because for something to be considered "alive", it must meet the requirements of responding to stimuli, reproducing and growing, and must be dependent on its environment. Water itself cannot be dependent on an environment, because it IS an environment.

This is just my opinion though :)

Which is not the precursor for the de novo purine biosynthesis?
amm1812

The correct option is (B) Lysine.

The precursors glutamine (N2 and N9), glycine (C4, C5, and N7), aspartate (N1), co2 (C6), and folate are used to create the purine ring (C2 and C8). All are precursors to the purine ring, with the exception of lysine.

How is Purine synthesized de novo?

  • In all cells, the cytosol is where purine biosynthesis takes place.
  • There are 11 steps that are catalyzed by enzymes that build the purine ring. Each enzyme includes several monomers because it is oligomeric.
  • The reaction does not release the intermediate products that are created. They are instead transported to the next enzyme in the process.
  • The biosynthesis process in the human body can provide the body's need for purine in metabolic processes. Clinical symptoms might become unpleasant if purine synthesis is inadequate or if biosynthetic routes are aberrant.

Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum
Volgvan

Answer:

The correct answer is - option A. Glass thermometer.

Explanation:

Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.

In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.

Thus, the correct answer is - option A. Glass thermometer.
