Answer:
A. A majority of scientists agreed with it
Explanation:
The famous theory called the theory of common descent, states that all the living organisms of the earth have arisen from a common ancestor. This notion was first proposed by a French mathematician,Louis Maupertuis duirng 1740s who was of the view that all organisms had a single ancestor and evolutionary process with the passage of time resulted in the specie diversification.
After that, in 1790s another philosopher Immanuel Kant, suggested that all organisms seem to have a common ancestor. In the same period of 1790s, another scientist , Erasmus Darwin who was the grandfather of Charles Darwin also suggested that all the organisms might have a single ancestor who went through the process of evolution to bring all the majesty into life.
Charles Darwin was the first scientist who worked on this notion for alot of time and proposed the theory of common descent,in his book, On the Origin of Species.
After it, many scientists got agree with this theory such as, Vernon Kellogg in 1907 and T. Ryan Gregory in 2008 and many others explain that no reliable observations exists which contradicts the theory of common descent.
Therefore, option A is the best option.

Answer:
i think it's "C"
Explanation:
because if both have similar structure then just have some relation
The two major types of aquatic biomes is Freshwater and Marine. The major factor that differentiates between the two aquatic biomes is difference in Habitat.
The two major types of aquatic biomes is Freshwater and Marine.
Freshwater regions include rivers and lakes with comparatively low salt concentration.
Marine regions include Ocean, and Estuaries with comparatively high salt concentration.
The Habitat of the Freshwater and Marine life is the major differentiating factor between them.
The survival of fish is also dependent on the type of Freshwater and Marine environment.
Like, the marine water fishes can survive in a water concentration with high salt concentration.
The working of the organs of the aquatic organisms in Freshwater and Marine determines the concept of osmosis and various life important activities needed for the existence.
Fish in salt water need to maintain stable drinking conditions to maintain healthy life.
Freshwater organism finds easier to get adapted to the water environment. They are less sensitive as compared to marine water.

Answer:
The cells are connected by gap junctions.
Explanation:
A gathering of protein channels, which permits small molecules and ions to move between the neighboring cells is termed as a gap junction. The protein channels that form gap junctions comprise two connexons, of which one is situated in the membrane of one cell that combines and aligns with the connexon of the adjacent cell.
This association produces a spontaneous pathway, which permits the small molecules and ions to pass passively from one cell to another. The gap junctions are found in all the kinds of cells, however, they are not found in skeletal muscle, RBCs, and blood lymphocytes.
Thus, the passing of the fluorescent dye from one cell to another shows that the two cells are connected with the help of gap junctions.
