The pap smear is ________ percent approximate in detecting cervical carcinoma
Katen [24]
Pap smear (Papanicolau smear) is a procedure that involves swabbing the endocervix (inner part of the cervix), ectocervix (outer part of the cervix), and the vaginal walls. This smear will then be fixed and then viewed through a microscope to check for atypical cells (or cancer cells). Pap smear has a 95% sensitivity so pap smear can detect cervical carcinoma 95% of the time.

slavikrds [6]

Answer:

Distinguishing between Similar Traits

Similar traits can be either homologous structures that share an embryonic origin or analogous structures that share a function.

LEARNING OBJECTIVES

Explain the difference between homologous and analogous structures

KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
