The left atrium lacks a group of pace maker cells.
There are three physical types of media, theses are solid, liquid and semi-solid.
In liquid media, growth occur throughout the media. In solid media, there are firm surfaces for bacteria to form discreet colonies. This type of media usually contain 1-5% agar. For semi-solid media, this type of media has soft constituency at room temperature and does not flow freely.

D. is correct: Koalas evolved after trout.
(A is false, B is also false bc amoeba are unicellular, C is false too, they are definitely not in the same class)
Valinomycin is an Ionophores- i.e it makes the inner membrane permeable to compounds which are ordinarily unable to cross.
The amphipathic molecules dissolve in phospholipid bilayers of the mitochondria
It shields the electric charge as the ion passes through the membrane, providing a polar environment for the ion and a hydrophobic face to the other side. mobile carrier catalyzes the electrical movement of K+ across phospholipid bilayers. Hence Accumulation of potassium inside the mitochondria
This dissipates the essential transmembrane electrochemical gradients causing tremendous metabolic upheaval in the mitochondria.
For the answer to the question above, I believe the answer is <span>"The forelimbs are similar because all of these organisms inherited the basic forelimb design from a common ancestor."
We've just evolved from our ancestor.
I hope my answer helped
