I would say the alveoli. They are tiny air pockets in the lungs: this is where the diffusion of oxygen and carbon dioxide occurs.

Hope this helps! x

A patient presents with low copper. which portion of cellular respiration would suffer?
Alex73 [517]
Copper deficiency is a rare disease that leads to hematological disorders. It is an essential trace element. It is an essential part of some enzymes (c0-factor) that plays role in cellular respiration. Copper is also an anti-oxidant that scavenges free radicals. In case of cellular respiration copper is responsible for electron transfer of oxygen.

Deb is studying the difference between 2 types of soil. She notices that her plants grow more when they have additional nitrogen
Dennis_Churaev [7]

The molecule, which the plant is most likely synthesizing using the extra nitrogen is PROTEIN.

Plants and animals do not have the capacity to use atmospheric nitrogen as nutrient. Atmospheric nitrogen has to be converted to forms that are usable by plants and animals before they can utilize it. Nitrogen fixing bacteria are the ones that are responsible for converting atmospheric nitrogen to the forms such as nitrate and ammonium, which can be used by plants. Animals get their own portion of nitrogen when they eat plants or other animals. Nitrate is the form of nitrogen that is mostly used by plants. Excess ammonium in plants are usually used directly to synthesize proteins. Nitrogen is a very important component of chlorophyll, which is essential for photosynthesis. Nitrogen is also found in the genetic materials of plants and it is needed for their growth and development.  Animals used nitrogen to synthesize proteins, nucleic acid and other biological compounds that contain nitrogen.

Why do we need to de-starch a leaf to proceed with an experiment?
Ronch [10]
We de-starch leaves so as to remove the starch produced in it during photosynthesis stored as food. Removing the starch would help us to infer our observations clearly as there is no change or substance that would effect the experiment we want to carry out. For example , the indicators we use might give blue-black or green colors just because of the presence or absence of starch.

a culture of e. coli is irradiated with uv light. the highest frequency of mutations would be obtained if after the irradiation,
Klio2033 [76]

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

  • A base (adenine)
  • T base (thymine)
  • G base (guanine)
  • C base (cytosine)

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.
