Answer:
B
Explanation:
Neurotransmitters such as acetylcholine, epinephrine are important at a neuron-neuron junction called synapses. When an impulse reaches the end of one neuron, at the synapse, it causes the release of neurotransmitters from synaptic vesicle that diffuse across the synapse and when they bind to their reports on the other end. An impulse is then generated on the subsequent neuron that travels down the axon to the next synapse.
Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
I think the answer to this is D.
While looking at a cell under a microscope, a scientist is able to see a
biological molecule. This molecule is a nucleic acid with double
strands and
<span>
contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, the scientist can conclude that </span>"
The nucleic acid is DNA and would be found in the cell’s nucleus."
