Answer:

False

Explanation:

The glycocalyx is the layer surrounding the plasma membrane of the eukaryotic and prokaryotic cells.

The glycocalyx is composed of the carbohydrates and the protein molecules like the proteoglycans, glycosaminoglycans and the other glycoproteins.

The glycocalyx has been identified in the bacterial cells as a protective layer from the host bu in eukaryotes the glycocalyx helps in the cell to cell interaction and communication.

Since the glycocalyx is not composed primarily of the proteins but of the carbohydrates and the proteins therefore false is the correct answer.

Answer: False. It is not glycocalyx.

Explanation:

Glycocalyx is a carbohydrate enriched membrane bound layer that surrounds the cell plasma of eukaryotic cells and prokaryotic cells, especially bacteria. It act as a barrier between the cells and its environments. In bacterial cell, it act as protective coat from host factors.

Glycocalyx help in cell to cell interaction or communication in eukaryotic cell. It is involved in diseases development and progression.

Varvara68 [4.7K]

Answer:

Nephrons in birds, mammals, and reptiles are all extremely similar, more so than other structures in the bodies of different species, solidifying the relatedness through similarity.

Explanation:

Birds can be said to have "mammal-like" nephrons from the number of loops and overall structure of their kidneys, which, although they look very different, serve the same purpose and do it in largely the same way. Reptiles also have mammal-like nephrons, and it can be assumed that this evolutionary trait was kept because the specific structure of the nephrons is generally the most efficient.

TRUE OR FALSE:
pentagon [3]

Answer:

The given statement is false.

Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.  

Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.

Thus the amount and type of precipitation in tropical and temperate rainforests are different.
