Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
The nucleus controls everything in a cell
Answer: D.
Explanation: Members of the same species do not have the same number of cells. Think differences in height or weight. They do not have identical traits. Think siblings. They cannot create different species. Two wolves cannot make a coyote.
Glycine is an amino acid coded by GGA, GGU, GGC, GGG codons. Histidine is an amino acid coded by CAC, or CAU codons. It should be known that the mRNA chain that will be encoded must always have a START codon at the beginning and a STOP codon at the end.
Answer:
Los organismos unicelulares se componen de una sola célula que lleva a cabo todas las funciones necesarias por el organismo, mientras que los organismos multicelulares utilizan muchas células diferentes para funcionar.
