Answer:
Explanation:
Dispersion and vicariance are the processes by which speciation is generated in biogeography.
A phylogeny represents the evolutionary relationships between different species.
In this phylogeny, species 5, 1, 6 and 3 originated from vicariance processes, and their position in the phylogenetic tree is due to the order of separation of the mentioned regions. Species 2 and 4 originated from dispersal processes, and are expected to have a closer evolutionary relationship with the species that were in the areas from which they were dispersed, in this case, with Africa and Australia respectively.

Mitochondrion
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
Answer:(B) decrease protein production
Explanation: nitrogen gas in the atmosphere is the source of nitrogen which is useful to plants.
In the nitrogen cycle, nitrogen gas is converted to it's compounds and then back to it's gas form.
The nitrogenous cycle involves fixation, mineralization, nitrification and denitrification .
In the first three states, nitrogen undergoes changes into a state where it can be absorbed by plants.
In denitrification,nitrates (useful form of nitrogen) are converted into gaseous nitrogen.organisms involved in this process are called denitrifying bacteria eg Pseudomonads sp.
Nitrogen is an important element.
It is useful for the production of protein, DNA, RNA and chlorophyll.
When it is deficient in the soil,it affects the synthesis of proteins and yellowing of leaves due to decrease in chlorophyll
A trilobite. Trilobites became extinct about 250 million years ago while a ammonite became extinct around the same time as dinosaurs(65 million years ago). You wouldn't find a human skull or a dinosaur footprint
