Answer:

Decrease a person ability to hear because pinnae funnel sound into the ear canal and if its enlarge example swollen, the tunnel will be more narrower for sound to pass

Answer:

C. Decrease a person’s ability to hear because pinnae funnel sound into the ear canal

Explanation:

In mammmals, especially humans, the pinna also known as auricle is a large fleshy cartilage outer structure of the hear which is situated on the lateral aspect of the head. The pinna direct sound waves toward the auditory canal. Although the pinna may direct sound into the auditory canal  but this portion of the ear is not vital for hearing.

The only main importance of the auricle is just to capture sound, the most important aspect of the outer ear is the ear canal itself, if the ear canal is not open, hearing will be dampened.

When both participants in a species' interaction develop adaptations in direct response to one another, this could progress into
fomenos

Answer:

coevolution

Explanation:

Coevolution refers to the process where two or more species modify each other's evolution via natural selection. Darwin mentioned how insects and flowering plants could coevolve by reciprocal evolutionary modifications. Coevolution has firstly been associated with mutualism between species including, for example, birds and flowering plants. However, coevolution may also involve host-parasite relationships, such as associations involving parasitic organisms and their sexually reproducing hosts. Finally, there are situations where coevolution involves both parasitism and mutualism (i.e., antagonistic coevolution).

In what two ways are active transport proteins similar to enzymes
Ksju [112]
  1. They change conformation/shape when the right molecule bind in their active site.
  2. They enable reactions to proceed ‘downhill’. For enzyme, when the reactants are more than the products, the reaction proceeds to the right of the reaction. Career proteins also carry molecules down their concentration gradient.
  3. Both career proteins and enzymes are not denatured  during the process of their biological activity

Len [333]

Answer:

D. 3 mi/min

Explanation:

Given:

Distance = 75 miles

Why can overproduction underproduction and production of proteins at incorrect times be a problem?
lyudmila [28]

Answer:

Overproduction can cause many diseases like

Proteinuria and  Amyloidosis

Underproduction may also leads to many problems like

Celiac disease and Congestive heart failure

Production of proteins at incorrect times may lead to severe conditions like

Ulcer

Explanation:

Overproduction of Proteins:

Proteinuria

This is the condition caused by the overproduction of proteins within the body. The urine of Proteinuria patients contains an abnormal amount of protein. This is linked with kidney disease. Filtration damage in kidneys causes the release of proteins like albumin leak in the urine.

Amyloidosis

This is the disease in which amyloid protein in high concentration get deposited in the organs, which causes these organs to malfunction. Organs which are affected by this condition are kidneys, heart, spleen, liver, nervous system, intestines or stomach.

The Underproduction of Proteins:

Low level of protein production can lead to many conditions such as

Celiac disease:

This is the disease in which the patient is intolerant to gluten protein which can damage the small intestine by activating the immune response.

Congestive heart failure:

This is the condition in which heart-pumping power becomes weak due to the underproduction of heart muscles.

Production of proteins at incorrect times:

Incorrect timing of the proteins may lead to severe conditions like

Ulcer:

The Stomach produces enzymes pepsin and HCl which cause the food to digest. If this protein produces at the wrong time with regular interval it may cause Ulcer.

The phenotype of an animal typically does not depend on A) the genotypes of the parents. B) seasonal changes in the environment.
ratelena [41]

Answer: The correct answer is-

C) The source of the animal's food.

Phenotype of an organism can be described as the physical characteristics or traits that the individual possesses ( such as hair color, eye color, skin color).

It is depicted by the genetic makeup ( that is genes) of the organism that is inherited from parents and is also influenced by some environmental factors.

Thus, it does not depend on the source of the animal's food.

Therefore, option C) is the right answer.
