Analogy refers to traits or structures like body shapes, fins which evolved independently that are similar in organisms that are not related by the same common ancestor. For example dolphins and shark have similar body structures like fins but they are unrelated. Whale and shark too. Whales are mammals, sharks are fish.
Homology refers to traits or structures
posses by organisms that are related by common ancestors. Example wolf and whales.....they are both mammals.
<u>Answer</u>: The energy source that generates wind is actually the sun.
<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.
Answer:
Beginning the age of European exploration
Explanation:
Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
Answer:
It is important to have a standardized system of classification so people can easily identify different things. It allows scientists to identify, name and group different organisms. It is important so scientists are able to easily communicate about different organisms without confusion.
It is necessary to classify organisms because: It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences
if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world. Instead, all organisms would be categorized differently in every part of the world, with different names.if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world.
