By defining diffusion we know that it is a movement of molecules from a region of high concentration to a region of low concentration. What this does is to evenly distribute molecules in a given area. In the case of spraying air freshener in a large room, the volume of air freshener will be evenly distributed around the room. Hence no specific corner in the room will have too much or too little.
Answer:
I will add the following statement:
<u>Taxonomic determinations were made based on the general lineage species concept.</u>
Explanation:
Taxonomic determinations show inferred evolutionary relationships in the form of multiple branching lineages connected by nodes. So, the sequences can easily be identified at the end of branches. And these taxonomic determinations were made based on the general lineage species concept.
Hence, I will add the following statement:
<u>Taxonomic determinations were made based on the general lineage species concept.</u>
The answer is a process that selects variation that help survival and that spreads the variation to more offsprings.
The idea is that there is a higher chance of survival if the organisms has certain characteristics and it is more likely to pass on their genes of this characteristic to the next generations.
For example, there's dark colored fish and white fish. In the deep ocean, dark colored fish can camouflage themselves. However, white fish can be seen easily by predators. Therefore, eventually more dark colored fish survives and more offsprings are dark ones.
Answer:
Dendrites
Explanation:
Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.
