If the facts about proton pumping are true, then protons are pumped into the matrix of the mitochondria.
<h3>What causes the electron transport chain's proton pumping?</h3>
Proton pumps are found in the electron transport chain's complexes I, III, and IV. The complexes absorb the energy generated when electrons migrate energetically downward and use it to pump H +start superscript, plus, end superscript ions out of the matrix and into the intermembrane gap.
<h3>when outside of the Matrix are protons pumped?</h3>
At complexes I, III, and IV, the matrix is pumped of protons (2 per complex). The resultant proton gradient drives ATP synthesis: 2 H+ are generated for every ATP. The inner mitochondrion is charged differently due to the proton gradient.

Answer:
the correct answer would be D
Explanation:
Meiosis I
Prophase I - homologous chromosomes form a tetrad, where they begin cross-over through the process of synapses.
Metaphase - homologous chromosomes then align along the metaphase plate.
Anaphase I - spindles then separate the homologous chromoses, pulling them to opposite poles of the cell
Telephase I - the cell creates a cleavage burrow inwhich the cell divides into two new cells with 46 chromosomes in the process of cytokinesis
Meiosis II
The same as mitosis
Prophase II - Nuclear envelope disintegrates, Sister chromatids migrate towards the metaphase plate.
Metaphase II - Sister chromatids align along the plate by their centromere.
Anaphase II- spindles pull the chromatin to opposites poles
Telephase II- cleavage burrow forms and cells seperate through cytokinesis
end result
4 haploid gametes are formed
Capsid proteins basically "trick" the cell by sticking to receptors on its surface.
Hope this helped thy out.
Answer:
<h3>The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.</h3>
