forsale [732]

Codominance or incomplete dominance is the answer in this question. This pattern of color expression is most likely to be an example of incomplete dominance or codominance. Codominance is defined as a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. Incomplete dominance on the other hand is a form of intermediate inheritance in which one of the allele for a specific trait is incompletely expressed over its paired allele.

In terms of ATP, how much more energy does the aerobic respiration process produce?

andrew-mc [135]

Answer:

Aerobic respiration process produce either 36 ATP or 38 ATP depending on the amount of NADH moles while Anaerobic produces 2 ATP. Aerobic respiration produces 32-34 ATP more

Explanation:

Aerobic respiration has 3 steps which includes; Glycolysis which produces 2ATP; Krebs cycle which produces 2 ATP and Electron Transport Chain which produces 32 - 34 ATP depending on the molecule of NADH introduced into the reaction from the kreb cycle

iVinArrow [24]

Answer: Option C

Explanation:

Color blindness is a common hereditary condition which means it usually passes from parents. Red green color blindness is passed on from the mother to the son.

The chromosome number 23 is the sex chromosome also responsible for colorblindness. As it is sex linked the son can receive the recessive allele from the mother.

The mother of the child had a recessive allele which she transferred into her son. As it is sex inherited disease the son is affected by gene carried from mother.

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex

OLEGan [10]

Answer: From the question,the correct order of how hearing works is listed below:

--> sound wave is generated from hitting a key on a piano,

--> Incus moves,

--> Stapes moves,

--> Sound wave enters inner ear,

--> Fluid in the cochlea moves,

--> Fluid wave moves across Organ of corti based on frequency,

--> Ions enter hair cells,

--> hair cells bend,

--> auditory nerve transmits the signal to the auditory cortex,

--> auditory cortex recognizes the sounds.

Explanation:

In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:

--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)

--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).

--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).

To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.

As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.

In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.
