A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms.
Answer is: <span>patient demographics and social history.
</span>Patient demographics is<span> for the identification of a patient and his categorization into categories for the purpose of statistical analysis.

The four phases of the menstrual cycle are menstruation, the follicular phase, ovulation, and the luteal phase. Common menstrual problems include heavy or painful periods and premenstrual syndrome (PMS). Knowing when in the menstrual cycle a woman is most likely to conceive can increase the chance of pregnancy.
Two organisms have the same phenotype but different genotypes when One organism is purebred dominant, and the other organism is heterozygous. So, the correct option is B.
<h3>What do you mean by Genotype?</h3>
Genotype may be defined as the ultimate combination of those alleles which are selected for specific studies.
When an allele is dominant over others, its purebred dominant and heterozygous (hybrid) may have different genotypes but the same phenotype.
Therefore, the correct option for this question is B.

Answer:
Chemically gated Na+-K+ channels
Explanation:
The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.
When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.
Thus, Chemically gated Na+-K+ channels is correct.
