Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius

Answers

Answer 1

Answer:

The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.

Explanation:

The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.

The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.

The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.

How does oxygen enter the urchins system?

Answers

Answer:    

Enters through the gills and tubed feet.

Explanation:

The oxygen obtained by a Purple Sea Urchin is dissolved in water.  Oxygen enters through the gills and tubed feet. When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through the body (through the canals).

Any Questions?

Oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.

What is the water vascular system?

The water vascular system is seen in the phylum of the echinodermata, which is essentially a network of canals and tube feet that run throughout the urchin's body, and the tube feet are helpful for the attachment to the surface and for the respiration. When the tube feet are extended, oxygen from the water diffuses across the walls of the tube feet and into the urchin's body, while carbon dioxide is released into the water.

Hence, oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.

The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38

Answers

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

__________ give you energy and help you feel satisfied after eating.

Answers

Animals, including humans, derive chemical energy from their food to support their metabolism, including their muscular activity.

What is the source of energy from food?

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

Cells release energy from nutrients through the process of respiration. The majority of the time, glucose has already been produced from the food.

Because they work quickly and provide energy as soon as they are taken, carbohydrates—which have 4 kcal per gram—are the foods that are used as an energy source the most frequently.

Therefore, food give you energy and help you feel satisfied after eating.
