The answer is; catalyst
These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.
One of the 4 nucleic acid bases. They connect the two strands of the DNA double strand by means of hydrogen bonds, the principle of so-called complementarity of bases. derived from pyrimidine. It is part of nucleic acids, where it forms a complementary pair with guanine using three hydrogen bonds.
Pigments absorb light used in photosynthesis.Set of wavelengths that a pigment doesn't absorb are reflected.
Answer:
1. Mitochondria
2. Chloroplast
3. the formation of eukaryotic cells
4. DNA
Explanation:
The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.
The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.
The evidence which supports their ar:
1. The same size of the organelles to the bacteria
2. The presence of the circular DNA of the organelles like bacteria
3. The similarity in the 30s and 70s ribosomal subunits.
Emperor penguins need lungs to breathe. In penguin lungs, air never stops. ... Once the air goes farther into the trachea it splits into two different directions into both lungs. To get the oxygen into the blood cells, it must come "within small distance of the penguin blood cells".
