Answer:
The tail of an ATP molecule is made up by 3 phosphate groups link together by the help of 2 high energy phospho anhydride bonds.
Explanation:
ATP or adenosine tri phosphate is an energy rich compound that contain adenine base, ribose sugar and 3 phosphate groups.
These 3 phosphate groups makes up the tail of ATP molecule.The 3 phosphate groups are designated as alpha phosphate,beta phosphate and gamma phosphate starting from the C5 atom of ribose sugar.
When ATP undergo hydrolysis the terminal phosphate group or the gamma phosphate group is cleaved from the ATP molecule resulting in the formation of ADP and inorganic phosphate along with the generation of high amount of free energy that is utilized by the cell to perform various cellular and physiological activities.

Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.
Answer:
This suggests that the moustache is a releaser for aggression.
Explanation:
<em>Fixed action patterns</em> are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called sign stimuli or releaser. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed.
The black feathers resembling a mustache in a <em>Northern flickers</em> male are an external sensory stimulus. This trait that can provoke another male to respond aggressively, as a f<em>ixed action pattern</em>.
This trait might be considered as an <em>unconditioned stimulus</em>, which <em>provokes an unlearned or reflex reaction</em>. These aggressive responses are triggered by reflex.
