Answer:
Embryotic stem cell research benefits our society with the possibility of it helping various diseases and it only requires a small number of cells. The negatives of stem cell research are the cost and ethical controversary. To start, stem cell research could help with diseases like Alzheimer's and certain cancers like Parkinson's. Also since cells replicate incredibly fast, procedures wouldn't need many cells depending on the case. Stem cell research can vary in costs from about $5000 to $20,000 which for many people is difficult because stem cells are very temporary in many cases. Many groups of people don't agree with stem cell research since human embryos are destroyed in the process of harvesting embryonic cells and it is "potential life".
Thats all i could do i hope this helps
<u>Answer:</u>
<em>Scientists are constantly learning more about fossils to understand the evolution of earth and other living species.</em>
<u>Explanation:</u>
It helps to study the structure of the organisms that are already extinct. Fossils are the conserved remains or traces of animals, plants, and other organisms that exist no more.
Fossils are the significant proof for evolution as it demonstrate that organism on earth was unique from the organism found on earth today. It is also used to study the tectonic history.
Answer:
Chlorophyll a is the chief pigment associated with photosynthesis. As we can see,chlorophyll a absorbs red and blue wavelengths to a higher extent. Green light isn't rejected but rate of photosynthesis is more with red and blue wavelengths of light.
Explanation:
The spectral absorbance of photosystems and chloroplasts is lowest for green light...
All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color.
That would be the mitochondria. They produce the energy needed for activities that occur in the cell, thus its being called the "powerhouse of the cell"
