Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
Answer:
Option A, The animal can only live in Australia
Explanation:
At present the Koala are found in several states of Australia such as
a) Queensland
b) NSW
c) Victoria
d) South Australia
Though the Koala is found on the eucalyptus trees of the temperate rain forest , they are only found in Australian geographies . There are several other place on planet earth where there is rainforest with eucalyptus trees and temperate climate, even though the Koalas are limited to Australia.
Hence Option A is correct.

Prokaryotic have no organelle but the eukaryotic do have cells
C)old or young
A dichotomous key is a tool or a used assessment that is utilized by most scientists like biologist and ecologist to organize and classify organisms into sets of classifiable structures like trees, animals, birds, cats, dogs. These are broad descriptions that systematizes a whole family of species into a set category or a whole kingdom in a simple language such as plants or animals.
