All proteins are synthesized by ribosomes in the cell. some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. most proteins made by free ribosomes function in the cytosol. proteins made by bound ribosomes either function within the endomembrane system or pass through it and are secreted from the cell. which of the following proteins are synthesized by bound ribosomes?

Answers

Answer 1

Answer: ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.

Answers

Sunny's poster has a couple of errors in the direction of the arrows. The correct directions of the arrows should be:

Arrow A should point to the tissue (not the organ system).
Arrow B should point to the organ (not the cell).
Arrow C should point to the organ system (not the muscle tissue).

The correct order of the levels of organization in the human body is:

Cells
Tissues
Organs
Organ systems
Organism

Therefore, arrow A should point to the tissue (a group of cells that perform a specific function), arrow B should point to the organ (a structure made up of tissues that work together to perform a specific function), and arrow C should point to the organ system (a group of organs that work together to perform a specific function). By correcting the directions of the arrows, Sunny's poster will accurately represent the levels of organization in the human body.

What is the leading cause of water contamination in countries without water treatment plants?

Answers

Answer: Sewage

Explanation:

The leading cause of contamination in the countries without having water treatment plants is sewage. The sewage disposal is the main waste that needs to be treated.

Sewage has many harmful bacteria growing on it. This can be unhealthy if people are exposed to it. Sometimes the pipes leakage can take place infecting the nearby water bodies.

This can be a very serious issue affecting the freshwater which is used by the people for many domestic and commercial purposes.

The answer is sewage
