Answer:
The accurate description for the binary star systems are that they have stars that might appear to wobble and also, often have one star that is brighter than the other. The binary star systems are often refer to as the double star system which consists of only two star in the system.

Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.
Answer:
Cells will progress through mitosis even when they are not ready.
Explanation:
Being a protein, cyclin controls the progression of cell in the cell cycle, when its concentration will be more it activates cyclin dependent kinase enzyme which are necessary in the synthesis of cell, hence mitosis occurs even when it is completely not ready for it. In this condition cytokinesis will not occur and hence mitosis will occur in which the cell will divide with more than one nucleus. This type of cells are called multinucleated cell.
