What do structures B and C have in common?
A.both contain chyme
B.both contain partially disgested food
C.both contain waste material ready for removed
D.both contain stored food
The structures B and C have in common is that both contain partially disgested food. Thus, the correct option is B.
What are structures B and C here represent?Structure B represents the food pipe or esophagus, while structure C represents the stomach.
Chyme is produced only when food is fixed with gastric juice which is only present in the stomach, hence option A is incorrect.
Waste material is found in the rectum of the body structure, not in the esophagus and the stomach. Thus, option C is also incorrect.
Therefore, the correct option is B.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which
type of limiting factor causes this?
density dependent
density independent
population dependent
population independent
Answer:
Density Independent
Explanation:
Density independent is the factor that will affect a population no matter its size. Temperature, natural disasters, and oxygen levels all influence this.
The correct term to describe the type of limiting factor that causes the destruction of both the small population of trees and the large population of birds in this scenario is "density-independent." Density-independent factors are environmental factors or events that affect populations regardless of their size or density.
What is density-independent?Density-independent factors are environmental factors or events that affect populations regardless of their size or density. These factors exert their influence on population dynamics independently of population density. Density-independent factors include natural disasters like earthquakes, floods, hurricanes, and forest fires, as well as extreme weather events, habitat destruction, pollution, and certain diseases.
In this case, the forest fire is an example of a density-independent factor because it can impact both the tree population and bird population regardless of their respective sizes or densities.
Therefore, the correct answer is "density-independent."

The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. How does this promote evolution?
The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. This promote evolution because the environment selects the most evolved animals to survive that environment.
What is the evolutionary process?Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. When new species of organisms are formed from gradual changes in preexisting species.
So although there are several eggs initially only those that survived the environment are able and evolved to reproduce, so the evolution of species is carried out.

What is the function of surfactant on the inner surfaces of alveoli?
What are the microscopic structures within the lungs?
What important information did you learn about from this video?
Answer:
1-The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
2-The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.
3-The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.
4-The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.
