Answer:
D. The auditory tube drains into the nasopharynx.
Explanation:
The auditory tubes, commonly known as eustachian tubes have their pharyngeal openings in the lateral wall of the nasopharynx. Auditory tubes also prevent the mucus to enter the middle ear by channelizing it into the nasopharynx. This clearance of mucus does not allow any infection to spread to the middle ear.
The correct statement about the pharynx is that the auditory tube drains into the nasopharynx.
The correct statement about the pharynx is D. The auditory tube drains into the nasopharynx.
The palatine tonsils are actually embedded in the lateral walls of the oropharynx, not the nasopharynx. The pharynx contains the larynx, not the vocal cords. And the pharyngeal tonsil is located in the nasopharynx, not the laryngopharynx.

The correct answer is:
"A karyotype can be used for reporting medical concerns and possible genetic disorders
Explanation;
A Karyotype is the number of the chromosome in a cell. In humans, the typical amount of chromosomes is 46. Seldom humans have a varying number of chromosomes and then the karyotype (for example the number) can be used for inscribing for example of genetic disorders- so the answer is that it can be used for reporting of genetic disorders.
B. Viruses have no RNA.
C. Viruses have no metabolism.
D. Viruses have a protein shell that protects them.
Explanation:
Meiosis I has one diploid parent cell and ends with two haploid daughter cells, splitting the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
Autotrophs and heterotrophs are two main types of organisms based on how they obtain energy. Autotrophs can produce their own food through photosynthesis, while heterotrophs rely on consuming other organisms for energy.
Autotrophs and heterotrophs are two main types of organisms based on how they obtain their energy. Autotrophs can produce their own food through photosynthesis, while heterotrophs rely on consuming other organisms for energy. Autotrophs typically contain chloroplasts and are capable of converting sunlight into glucose, such as plants, algae, and some bacteria. Heterotrophs include animals, fungi, and most bacteria, which obtain energy by consuming organic matter.
