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.

Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.

What are the possible genotypes of the parents of a male child who is colorblind?

viva [34]

Color Blindness is an X-linked trait. This explains why males are much more likely to have it than females. Offspring inherit Color Blindness from their mother, because the father only contributes the Y chromosome. A female can only have the disorder if her father has it and her mother either has it or is a carrier

Many fish species release thousands of eggs during reproduction. Which factor helps keep these fish populations from becoming to

Sophie [7]

two factors that determine range are, in constant flux as abiotic and biotic factors change overtime Abiotic factors - temperature, rainfall, the presence of geographical structures like mountains and oceans, and large scale ongoing and historical process such as continental drift Biotic factors - past and current presence of other species that provide habitat, food, or competition Ranges are dynamic

What has allowed animals to adapt over time?

jeka94

Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.

Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.

<h3>What is an adaptation?</h3>

A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
Among the adaptations that helped animals live and prosper on land are:

Gas exchange using a moist membrane
The ability to traverse land (limbs instead of fins)
The capability of body water conservation
The capability of reproduction and early habitability
The capacity to endure fast environmental changes

<h3>What are the types of adaptation?</h3>

Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.

Physiological- When an animal's body's internal mechanisms adapt to its surroundings.

Structural - Over the course of millions of years of evolution, the animal's bodily features alter.

Behavioral - Animals adjust their behavior in reaction to their environment.
