Answer:
External auditory meatus
Explanation:
The pinna leads into the external auditory meatus which is a tube that directs sound waves to the tympanic membrane. The tube is lined with hairs which trap solid particles that may enter the ear. It is also lined by wax secreting cells whose function is to secrete wax that traps dust and prevents entry of solid particles. The wax also maintains the flexibility of the eardrum.
Answer:
I personally believe that lab experiments are useful and an effective way to test and gather data. Even though they can often lack ecological validity and mundane realism they can easily be replicated and results can be retested, helping to prove/disprove data, ultimately leading to the creation of practical applications.
- That psychologist can make statements about cause and effect because they involve the deliberate manipulation of one variable while trying to keep the other variables constant, unlike non-experimental methods.
- Lab experiments can also be replicated due to the standardised procedures and measures, ultimately making it easier to check the reliability of the research/results and prove/disprove results if the research is conducted by another researcher.
C. Law of segregation is the Mendel's law that states that gametes carry one allele for each trait.
The correct answers are:
• Liver cells are abundant in SER.
This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.
• The testes and ovaries are tissue types whose cells are abundant in SER.
This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).
• Cholesterol is made in the SER.
ER is the organelle at which all membrane lipids are synthesized.
• Phospholipids are synthesized from cytosolic water soluble precursor molecules.
Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
It is the sun. You start with photosynthesis.
