There were more dark moths around factories because trees were darker near factories because of pollution. More light moths were found in the country away from the factories, in the forests with no factory pollution
If your choices are the following, then the correct answer is C:
a. The aerobic bacteria were able to capture the sunlight and generate sugars from it.
b. The aerobic bacteria helped protect the cell against desiccation.
c. The aerobic bacteria metabolized sugars and generated large amounts of ATP.
d. The aerobic bacteria helped protect the cell against predation.
This is actually the endosymbiotic theory of how we humans (and other organisms alike) have evolved to have mitochondria inside our cells. Evidence to support this is that mitochondria have their own DNA different from ours.
<em>A</em> can't be the answer because that is more related to plants. <em>B and C </em>are also wrong because they simply do not provide those functions.
Answer:
About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.
Hope this answer is right!!
Cell X is likely a prokaryotic cell. Option B) is the correct answer.
<u>Explanation</u>:
- The prokaryotic cells are present in unicellular organisms such as bacteria and lack Nucleus in it. The cell X is not filled with x-mark in the nucleus.
- The prokaryotic cells consist of the cell membrane, cell wall and a genetic material composed of DNA. All these are marked with x-mark for cell X.
- Chloroplasts are not present in prokaryotic cells and the space for it is left blank in cell X without the x-mark.
- This information clearly shows that prokaryotic cell structure is viewed likely in cell X.
