Answer: D. Atomic Number
Explanation:
Atomic number of an element is the number of protons in the nucleus of an atom the element. An atom has three fundamental particles: protons, electrons and neutrons. Protons and neutrons are found in the nucleus of an atom while electrons are found outside the nucleus. The atomic number of an element determines the properties of the element. No two atoms of different elements have the same atomic number, but two or more atoms of the same element can have the same atomic number but different atomic masses. When atoms of the same element have the same atomic number but different atomic masses, they are said to be isotopes.
The answer is nucleus.
EXPLANATION
Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes.
The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes.
Well, a eukaryotic has a Membrane-Bound Nucleus.
I wish you added the diagram but I can tell that the long strings are the spindle fibres.
there is growing evidence that mitochondrial complexes i, ii, iii, and iv are part of a larger supercomplex. the advantage of having all four complexes within a supercomplex is that it makes the electron transport across various complexes easier and faster.
Mitchondria have four types of complexes-
Complex I- NADH/ ubiquinone oxireductase, blue
Complex II- Succinate dehydrogenase, pink
Complex III- Cytochrome c reductase
Complex IV- Cytochrome c oxidase
The electron flows through the various complexes in process of formation of the ATP molecules.
The advantage of having a supercomplex which accomodates all the four types of complexes is that the electron will then flow in solid state which is kinetically more favorable.
