Answer:
Neurons differ from other cells because neurons have extensions called axons and dendrites, they communicate with each other through an electrochemical process which we just talked about, and neurons have specialized structures such as synapses and chemicals such as neurotransmitters.
Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
The chances of producing male/female offspring is 50%
Answer:
The best answer to the question: Which process is the best interpretation of this scenario, would be: C) Microevolution.
Explanation:
Microevolution is defined as the changes in allele expression and frequency within a specific population and which take place within a relatively short period of time regarding evolution. There are different reasons why microevolution might take place, instead of genetic evolution at a much larger scale, and throughout a much larger period of time, which would be typical of macroevolution. These reasons are: mutations, natural and artificial selection, gene flow and genetic drift. In the case of the bird found in Galapagos by Peter and B. Rosemary Grant in 2002, the differences in the finches arose due to natural selection when confronted with a change in their climatic conditions, and therefore, the availability of food. These changes in the environment drove the birds with larger beaks to be first privileged in food acquisition and also in reproduction, making their genetic make-up more prevalent, while those with smaller beaks, due to shortage of food availability, became incapable of passing on their genes to future generations. Natural selection played its role and one set of genes expressed themselves more frequently due to the circumstances and the reproductive process. But when things changed, the situation reversed. This is all characteristic, given the small changes and the reversion, of microevolution, or evolution at a small scale.
