Answer:
A major change over long periods of time is best described as macroevolution.
Explanation:
Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.
Answer:
The electrical signal will not be converted into chemical signal.
Explanation:
The synaptic knob is the bulbous enlargement also called synaptic terminal preset at the end of the axon.
The synaptic knob is a living cell and thus contains all the living features but they also contain the vesicles which store the neurotransmitters, therefore, synaptic knob acts as a site which converts the electrical signal into a chemical signal. The released neurotransmitter from the synaptic knob interacts with the post neuron or recipient neuron.
If the mutation develops in the neurons which result in the formation of neurons without synaptic knob therefore the electrical signal will not be converted into a chemical signal and thus signal will stop.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.

Answer:
The companies take away the bottle as "security deposit and however they can recycle and reuse it."
Explanation:
When buying different beverages from a person distributing, a deposit needs typically to be paid to the distributor from the containers that have been taken. However, the distributor will issue a refund once the bottle that was taken has been returned to the place of purchase. Therefore, the distributor will reimburse the redemption of the retailer the amount that was deposited for every container. The additional handling fees usually added in some countries. The deposits that remain unredeemed are taken to the state or kept by distributors.
