Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>

Answer:
nucleus
Explanation:
The organelle would most likely be the nucleus.
<em>The nucleus happens to be a membrane-bound organelle that is somehow round in shape. It houses most of the genetic components of the cell, including proteins and nucleic acids in the form of DNA</em>.
<u>Fungi themselves belong to the eukaryotic category of living organisms and as such, every fungus cell is expected to have a nucleus and other membrane bound organelles such as mitochondrion. </u>
Hence, the organelle would most likely be the nucleus of the fungi cell.
Answer:
C. Niche overlap is small and the carrying capacities are similar.
Explanation:
The Lotka-Volterra model is used to predicts if coexistence of two species is possible .The Lotka–Volterra models show that coexistence is more likely if niche overlap is small and the carrying capacities are similar.

Answer:
The cardiac muscle is made up of branched muscle cells, which have 1 or 2 nuclei and which the contact area between the heart fibers gives rise to specialized regions at the level of the plasma membrane called intercalary discs. The intercalary discs unite the cardiac muscle cells with each other, which provides greater adhesion to the tissue and intervenes in the rapid communication between cells. This allows its simultaneous contraction and the production of the beat.
Explanation:
The intercalary discs are the union systems that associate the cardiac muscle cells to form the myocardial fibers, the cardiac muscle is the muscle tissue of mixed components, which is located exclusively in the walls of the heart. For this reason, it has the function of generating the necessary contractions for the blood to reach all parts of the body.The intercalary discs are a special type of intercellular junction, a gap that guarantees electrical communication between these cells; and on the other hand, it provides places of adhesion and anchorage of one cell with another. The intercalary discs provide the structural foundation that allows the heart to behave as a functional syncytium.
