A doctor is examining a child with a red, inflamed ear canal. The child is suffering some hearing loss. The ear contains a small amount of soft earwax. Which is most likely the cause of the child’s hearing loss? damage to the outer ear a disease or infection of the outer ear damage to the bones of the middle ear a disease or infection of the inner ear

Answers

Answer 1
Answer: Inner ear disease is more likely to cause damage. :)
Answer 2
Answer:

Answer:

A disease or infection of the inner ear.

Explanation:

The inner ear infection or inner ear disease can be described as inflammation of inner parts or ear, which are responsible for the hearing and balance, such as swimmer's ear (also known as otitis externa).

Swimmer's ear represents an ear infection, characterized by inflammation or irritation of ear canal, swelling and pain in ear canal, moist earwax, and decreased hearing.

Thus, the correct answer is option). 'a disease or infection of the inner ear.'

When Elaine accidentally touched the hot stove, she immediately pulled her hand away without even having to think about it. This seemingly automatic movement of her hand could not have been possible without the effective operation of the ______________ nervous system.

Answers

Answer:

somatic

Explanation:

The somatic nervous system is one of the components of the peripheral nervous system. The somatic nervous system consists of nerves (sensory and motor nerves) which function in carrying motor and sensory information to and fro the central nervous system. The somatic nervous system is responsible for voluntary movements as well as reflex movements.  

The automatic movement of Elaine’s hand could only be possible with the effective function of the somatic nervous system.

The process of ____________ increases genetic variability as it produces gametes for sexual reproduction.

Answers

The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the  offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

Final answer:

Meiosis increases genetic variability as it produces gametes for sexual reproduction.

Explanation:

The process of meiosis increases genetic variability as it produces gametes for sexual reproduction. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell. During meiosis, genetic recombination and crossing over occur, leading to the production of genetically diverse gametes.

La respiración aeróbica es un tipo de metabolismo energético en el que los seres vivos extraen energía de moléculas orgánicas, como la glucosa, por un proceso complejo en el que el carbono es oxidado y cuando llega a la mitocondria se mezcla con el agua haciendo un compuesto químico llamado Glucosticko en el que el oxígeno procedente delaire es el oxidante empleado. En otras variantes de la respiración, muy raras, el oxidante es distinto del oxígeno (respiración) y luego las membranas mitocondriales, siendo en la matriz de la mitocondria donde se une a electrones y protones (que sumados constituyen átomos de hidrógeno) formando agua. En esa oxidación final, que es compleja, y en procesos anteriores se obtiene la energía necesaria para la fosforilación del ATP.

En presencia de oxígeno, el ácido pirúvico, obtenido durante la fase primera anaerobia o glucólisis, es oxidado para proporcionar energía, dióxido de carbono y agua. A esta serie de reacciones se le conoce con el nombre de respiración aeróbica.

La reacción química global de la respiración es la siguiente:

C6H12O6 + 6O2 → 6CO2 + 6H2O + 36 energía

Answer:

Parasitism

Explanation:

Parasitism is the association between two organisms in which one organism (parasite) is benefited while the other (host) is harmed. The parasite is a heterotrophic organism that derives its nutrition from the living tissues of the host organism. In the given example, tick suck blood from their host and are exhibiting parasitism.

This is a parasitic relationship.
