Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

When plotting, mark the values as [tex]x[/tex] and [tex]y[/tex] values. Then go to the x-axis on the graph and plot the point x-axis point on the graph. Plot the [tex]y[/tex] point on the y-axis for the first [tex]y[/tex] point. Do the same for each point.

Answer:

The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;

This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. ... The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.

Cutting

Explanation:

Answer: 1. Leaves have a large surface area; this allows them to absorb more sunlight. They are also thin, meaning that carbon dioxide has a shorter way to travel.

                2. stomata allow the entrance of carbon dioxide. The more complex adaptations are of the internal leaf structure.

Answer:

b) carbohydrates

When white blood cells are unable to function correctly, the body is less able to fight bacteria and close wounds. People with uncontrolled diabetes may develop poor circulation. As circulation slows down, blood moves more slowly, which makes it more difficult for the body to deliver nutrients to wounds.

Answer:

The purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another. Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.

Explanation:

All of the finches evolved from one ancestral species and adapted to their specific niche. of them evolved from one ancestral species, which colonized the islands only a few million years ago.

Darwin's finches, which was residing in the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. All of the finches evolved from one ancestral species and adapted to their specific niche.

The evolutionary history of Darwin's finches is identified by a gene that explains variation in beak shape within and among species.

The major factor influencing the survival of the medium ground finches is weather and the availability of food.

As all of the finches evolved from a single ancestral species and adapted to their specific niche, it is a specific example of competitive advantage exhibited by Darwin’s finches.

Thus, the correct option is C.

Answer: D

Explanation:

Answer:

Evidence is proof, in some form or another, offered to defend a belief or a claim. Anecdotes are short stories told to illustrate a point or support a claim.

Frequent earthquakes in an area indicates that there are tectonic plates boundaries and there is sudden regression of underground rocks. Through the areas when there is sudden movement and dynamic stress along with the sudden triggering.

Tectonic plates are larger pieces of earth's crust  and uppermost mantle. Tectonic plates movement cause the earthquakes to occur.

The other types of earthquakes are that of volcanic earthquakes, induced earthquakes and collapse earthquakes.

Therefore, earthquakes are mainly due to various conditions and other environmental activities that are not under control.

Answer:

Answer below

Explanation:

Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.

Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.

In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,

Non-motile cilia are structures in a cell membrane that also increase surface area. Non-motile cilia are like oars that push through the cell membrane. They are thinner and longer than microvilli. Non-motile cilia are also called primary cilia.
