What can be inferred from this excerpt is : ( D ) Individuals with favorable variations survive and reproduce.
<h3>Effects of genetic variations in species</h3>
When the insecticide was sprayed some of the cockroaches survived and continued reproduction due to their resistance to the spray.Therefore it can inferred that although the cockroaches share the same genetic materials, the variations in individuals within the same specie played a role in the survival of some of the cockroaches.
Hence we can conclude Individuals with favorable variations survive and reproduce.

Answer:
When neurotransmitter molecules bind to receptors located on a neuron's dendrites, ion channels open. At excitatory synapses, this opening allows positive ions to enter the neuron and results in depolarization of the membrane—a decrease in the difference in voltage between the inside and outside of the neuron

Movement of a part superiorly is that you elevates when you move a part superiorly (closer to the top of the head), like shrugging your shoulders.
Answer:
Because mitosis is a cell multiplication
Explanation:
Mitosis is a cellular process that generates from a single cell, two identical cells in size and ploidia. Mitosis is a process of cell mutiplication that allows to transform the unicellular zygote into a multicellular organism; also allows the replacement of damaged or old cells for new cells in the different tissues.
