People started domestication in the beginning of the Neolithic era.
Answer:
Neurotransmitters
Explanation:
Examples of neurotransmitter are acetylcholine, epinephrine, dopamine, GABA, serotonin, and etcetera. They are released from synaptic vesicles in the presynaptic membrane. They then diffuse through the synaptic cleft or neuromuscular junctions and bind to their receptors on the postsynaptic membrane and invoke an impulse.
Eukaryotic cells are mostly found in Archea and multicellular organisms meanwhile prokaryotic cells are found in unicellular. The major difference between the two is eukaryotic cells have a nucleus, or a nucleotide region. Therefore I believe the answer is C.
Answer:
habitat loss, over-harvesting, and introduction of exotic species
Explanation:
Genetic variation in a population allows for phenotypic variation, meaning that different traits exist in the same population. When the environment changes, the members of the population are tested by natural selection with regards to how well adapted their specific traits are to the new environment. If the traits they have do not suit their environment, this results in reduced survival and fitness, leading to less of that trait in the population. However, if the traits they have are adapted to the environment, they become naturally selected for with better survivability and fitness (leading to a higher frequency of that trait in the population). Thus, evolution has occurred.
