Answer:
C. The process occurs in the mitochondria of Eukaryotes.
Explanation:
- In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.
- Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).
Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.
Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

Answer:
Yes
Explanation:
Yes, the impact on one species over time can impact ecosystem.
An ecosystem is consist of biotic and abiotic organisms. There is a major relationship between biotic and abiotic or biotic and biotic components.
The relationship between biotic and biotic components is called food chain, in which one organisms depends on others for their survival and balance the energy flow in the ecosystem. So impact on any one species in the food chain will impact the whole ecosystem.
For example: Plants are the producers in the food chain, and if plants will be impacted or destroyed over time, the consumers depending on the plants will die from starvation and disturb the energy flow in the ecosystem. Along with this, plants are also related to abiotic factors such as maintenance of oxygen and carbon dioxide in the atmosphere, so the balance of these gases will also get disturbed.
Electrons in oxygens are 8.
The first level has 2 while the second has 8 too
Answer:
180seconds
Explanation:
From the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.
Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters
To calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use the following formula;
Speed (m/s) = Distance (m) ÷ time (s)
Time = Distance/speed
Time = 5.4 x 10^10 ÷ 3.0 x 10^8
Time = 5.4/3.0 × 10^ (10-8)
Time = 1.8 × 10^2
Time = 180seconds.
I’m pretty sure ribosome? please don’t report if i’m wrong, havent done this in a while but hope it helps :)
