Answer:
Option 4: Mucosa, Submucosa, Serosa, Muscularis
Explanation:
The correct sequence of the wall in the alimentary canal from deep to superficial is Option 4: Mucosa, Submucosa, Serosa, Muscularis. This order is based on the layers of the wall that make up the alimentary canal. The mucosa is the innermost layer and is made up of epithelial cells that are responsible for absorption and secretion. The submucosa is beneath the mucosa and contains connective tissue, blood vessels, and nerves. The serosa is the outermost layer and is made up of connective tissue, which helps to protect and support the alimentary canal. The muscularis is the layer beneath the serosa and consists of smooth muscle that is responsible for propulsion and movement of food.
They are arranged in such a manner that hydrophobic cells remain inside and hydrophilic cells remain outside
This is because of their meanings
So to attract water they are arranged this way
Which of the images below represents a healthy coral reef ecosystem?
In the given image below image A represents a healthy coral reef ecosystem. Thus option A is correct.
The ecosystem present underwater and designed as building of reef and corals. Reefs are made up of colonies of coral polyps accumulated together in the form calcium carbonate.
Maximum coral reefs are made up of corals of stone and they protect coastlines from heavy storms and it is the great source of employment for local people. Coral reefs provides medicines as well as foods to a high number of population.
Coral reefs are sometimes get damaged from local and outer sources due to construction work and destructive fishing and provides medicines as well as foods to a high number of population.
Therefore,In the given image below image A represents a healthy coral reef ecosystem. Thus option A is correct.

Phosphorus is contained in living organisms, soil, and bodies of water. Thus, the correct answer for this question is D, i.e. all of the above.
The functions of Phosphorus are as follows:
Phosphorus is contained in the genetic material of living organisms. It is also present in the soil which is one of the essential primary macronutrients along with nitrogen and potassium. Phosphorus is also present in water bodies.
Therefore, phosphorus is contained in living organisms, soil, and bodies of water. Thus, the correct answer for this question is D, i.e. all of the above.

Answer:
When we observe the position of a star its position changes over the course of a year. It will return to the same position a year after the first measurement. This effectively proves that the Earth is in orbit.
