Not to be too picky, but the question ought to say a positively charge ion rather than atom.
I will assume that is what you mean. An ion, using ordinary means, will be positive if it loses electrons (which are negative).
An ion can never gain protons. Left alone, the nucleus will remain unchanged for the rest of eternity. D is wrong.
C is wrong. If electrons are gained, the ion will go negative.
B is wrong for the same reason D is. An ion can't gain protons and it can't lose them.
A is the answer.
Hey,
option (C) is right ...
Atrioventricular septum is the surface indentation that separates the atria from the ventricles.
<h3>What is an atrioventricular septum? </h3>
The interatrial and interventricular septal cross the atrioventricular annular plane and merge with the septum tricuspid and anterior mitral leaflet attachment at the septal atrioventricular junction, which is a critical region of the heart.
The tricuspid and mitral valves seem cruciate on a four-chamber view when both septa are converging, earning the term crux of the heart, cardiac crux, or crux cordis.
The atrioventricular septum, a septal component dividing the atria from the left ventricle, is a distinctive anatomic characteristic of the atrioventricular junction.
Therefore, the atrioventricular septum is the indentation that separates the atria from the ventricles.

Exocytosis occurred, where a vesicle or liposome is transported through the cell's cytoskeleton to the cell surface membrane to fuse with it, releasing the contents from within the vesicle and into the extracellular environment.
It does not matter if the vesicle or liposome had previously fused with a lysosome previously.
So long as it is a vesicle/liposome, which has a phospholipid bilayer membrane (I.e. the same as the cell surface membrane), and fusion occurs, it is exocytosis.
Hope this helps! :)
Answer:
b. Mitochondrial respiration
Explanation:
Mitochondrial respiration of plants involves the participation of two major electron transport routes:
1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.
2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.
Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane. This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).
