Explanation:
The North Atlantic right whale was classified as an endangered species in 2015. A major cause of death for these whales is collisions with shipping vessels. Several measures have been enacted to prevent such collisions in regions with a high abundance of right whales. In 2002 and 2006, shipping vessel lanes were rerouted around some of these regions. In 2008, speed restrictions were placed on the shipping vessels that were permitted to travel through these regions.
The graph below shows the estimated abundance of North Atlantic right whales from 1990 to 2015. The years in which these measures were enacted are marked on the graph.
The data in the graph is best supported by : ( D ) While changes to vessel lanes and speeds may have been beneficial to right whales, additional actions are needed to prevent population declines.
Description from the GraphFrom the data presented in the graph the population of the right whales was favored by the changes in vessels lanes but the population began to decline again in and around 2009 therefore this is evident that additional actions are needed to prevent population declines other than changing vessel routes and placement of speed restrictions.
Hence we can conclude that While changes to vessel lanes and speeds may have been beneficial to right whales, additional actions are needed to prevent population declines.

What are the structures and functions of the tissues lining the respiratory organs?
What is the function of water on the inner surfaces of alveoli?
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.

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.

This year, druehl, inc. , will produce hot water heaters at its plant in delaware, in order to meet expected global demand. To accomplish this, each laborer at the plant will work hours per month. If the labor productivity at the plant is hot water heaters per labor hour, how many laborers are employed at the plant?.
2400 laborers are employed at the plant in given case.
What do you mean by global demand?The overall demand around the globe for a good or service is called global demand.
N should represent the number of workers engaged at the plant. The total number of heaters made by all employees in an hour is:
watts = 0.15 watts per hour * N
The total number of heaters in a month will be:
heating units = 0.15 * N * 160
This must be 57600 to satisfy the anticipated demand, so:
If we solve for N using 57600 = 0.15 * N * 160, we get:
N = 57600 / (0.15 * 160) = 2400 laborers.

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.
