It serves as the blueprint for traits of all living things DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism's or each cell's development and reproduction and ultimately death.

tropical rain forests support more species per unit area than any other terrestrial ecosystem. what is one way rain forests are
TEA [102]

<em>Answer:</em>

<em>Rain forests recycle nutrients. (Apex)</em>

<em>Explanation:</em>

<em>Plants can convert atmospheric carbon dioxide to other carbon based compounds through photosynthesis. Rain forests are the largest carbon revisers and are responsible for most of the oxygen in the atmosphere  </em>

<em> </em>

<em>Basically they take in carbon dioxide,convert it to oxygen and then release the oxygen back into the environment. Thus helping to prevent the plant from heating up.</em>

If you suspect your culture of bacteria has 23 x 106 cells per mL, what would you want the final dilution to be in order to end
olya-2409 [2.1K]

The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × 10^6 .

For calculating the colony forming unit bacteria;

Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.

∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate

  23 x 10^6 cells per mL          =  96 × dilution factor

  Dilution factor  = 23 ×10^6 / 96

  Dilution factor  = 0.23 × 10^6

Therefore, the dilution factor in order to end up with 96 colonies of bacteria is 0.23 × 10^6 .

Anna007 [38]

Answer:

Starch + H2O = maltose

This reaction gives the Starch and H2O as the reactants and Maltose as the product.

Amylase is an enzyme which helps in the digestion of Starch molecules and its activity can however be measured through careful monitoring of the disappearance of amylase substrate which is in this case, starch.
