Which glands produce ear wax?
apocrine glands
eccrine glands
ceruminous glands
merocrine glands
The Correct Answer is C
A. apocrine glands: Apocrine glands are sweat glands found in regions like the axillae and groin. They secrete a thicker fluid that, when acted upon by skin bacteria, produces body odor. They are not responsible for earwax production.
B. eccrine glands: Eccrine glands are the most numerous sweat glands, found across much of the skin. They secrete a watery solution important for thermoregulation but do not contribute to earwax formation.
C. ceruminous glands: Ceruminous glands are specialized modified apocrine glands located in the external auditory canal. They produce cerumen, or earwax, which protects the ear canal by trapping debris and providing antimicrobial properties.
D. merocrine glands: Merocrine secretion refers to the method by which many glands, including eccrine sweat glands, release their products through exocytosis. These glands do not produce earwax and are mainly involved in sweat production.

Correct Answer is C
Explanation
A. Elastic cartilage CT:Elastic cartilage provides flexibility and maintains shape in structures such as the external ear and epiglottis. It is not strong enough to withstand the compressive forces required at the symphysis pubis.
B. Hyaline cartilage CT:Hyaline cartilage covers articular surfaces and provides smooth movement at joints, but it lacks the tensile strength and shock absorption needed at the symphysis pubis.
C. Fibrocartilage CT:The symphysis pubis is composed of fibrocartilage, which contains dense bundles of collagen fibers. This structure allows it to resist compression and tension while providing strength and flexibility to support the pelvis.
D. Dense regular CT:Dense regular connective tissue forms tendons and ligaments, which provide strong attachment in one direction. It is not suitable for the multidirectional stress placed on the symphysis pubis.
Correct Answer is A
Explanation
A. transcription:Transcription is the process by which the DNA sequence of a gene is copied into messenger RNA (mRNA). This mRNA then exits the nucleus and carries the genetic code to ribosomes for protein synthesis.
B. replication:Replication is the process of copying the entire DNA molecule to produce two identical DNA strands during cell division. It does not produce mRNA and does not involve transporting genetic information out of the nucleus,
