The nervous system is one of the most important elements for our existence and survival, since it allows the management, organization and functioning of the rest of the corporal systems.
The synapse is a communication mechanism that occurs between two or more neurons in order to massively transmit a nerve impulse in order to coordinate a function in the organism.
The Chemical Synapse is the type of major synapse in our body. In these synapses the information is transmitted chemically, through the sending by the presynaptic neuron of different neurotransmitters that the postsynaptic neuron captures through different receptors, whose action generates an alteration in the form of excitatory or inhibitory postsynaptic potential that may end or not with the generation of an action potencial by the postsynaptic neuron. They are versatile synapses, since some neurons can inhibit the action of others depending on what is activated. There is no physical contact between both neurons.
Answer:
d. how much genetic material you share with someone you might help
Explanation:
In family groups or populations there are certain behaviors that might have possitive effects on other individual´s fitness. These behavior are known as prosocial.
<u>Prosocial behavior</u> requires cooperation among individuals that are helping each other. Although sometimes this might implicate a sacrifice of the one that provides the help, in a long-term period the whole group will be beneficiated.
Altruist actions occur when one of the organisms help another one.
To explain these behaviors, Hamilton proposed an explanation for altruism as <u>"inclusive fitness"</u> (1964). According to this, <em>an organism might help another one if this helps beneficiate its genes, that are shared with the organisms that receive help</em>. The concept of inclusive fitness links the evolution of altruism with blood relationship. This means that helping relatives increases the reproductive success of the helping individual, as its genes are represented in the beneficiated relatives. Altruist acts occur to favor close relatives.
The inclusive fitness concept points to the strategy of an organism to ensure the maintenance of its genetic material in the population for a long period of time, even if it requires some kind of harm for itself or is in its detriment.
In organisms that reproduce sexually, in general, help is directed to the progeny, although it is not always like this.

I put them in order of smallest to largest, I wasn't 100% sure that's what you wanted, but I hope this helps!
Carbohydrates or starch polymers are formed by condensation which bonding together of monomers (monosaccharides) and loosing a molecule of water in the process. These polymers include glycogen and starch and they may be formed by aggregation of monomers in the cells assisted by enzymes.
Fat polymers are formed through the attachments of monomers such as alkyl or allyl chains, aliphatic or aromatic to one of the three hydroxyl groups of glycerol, consuming one or two or all 3 hydroxyl groups of glycerol now called mono, bi or triglycerides respectively.
Proteins polymers are compounds derived from amino acids monomers. Amino acids have carboxy snd sn smino group on the same carbon. The amino acids polymerize by condensation to form protein chains.
Size of the biomolecules is normally based on the molecules of concern, in this case i would state that fatty acids or fatty polymers usually have 4 to 28 carbon atoms, Starch contains about 30 glucose units (amylopectin) while number of amino acid units in a protein depends on the sequences of the bases in the gene that encode a particular protein.
