Answer:

Endoplasmic reticulum is the defective organelle in most CF.

Explanation:

This is because of  mutation(deletion) in the proteins of these organelle. The CFTR  protein -a transmembrane regulator get stucked inside the E.R, thus  the  CFTR chloride protein channel is blocked. Therefore the outflow of Cl and water  out of the cell  is obstructed.

Consequently, the mucus from blocked fluid flow, clogs the lungs, the fallopian tube, sweat duct, and other places.

Which of the following statements about the smooth endoplasmic reticulum is/are correct?
olya-2409 [2.1K]

The correct answers are:

• Liver cells are abundant in SER.  

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.  

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

Fill in the blanks: The original organism is called the _____________, and new organisms are called the _____________.
NARA [144]

Answer:

The original organism is called the <u><em>parent (ancestor)</em></u> , and new organisms are called the <u><em>offspring</em></u>.

Explanation:

Reproduction is one of the characteristics of life. Every living organism tends to give rise to another organism. The organism which gives rise to another organism is termed as the parent. The organism which is born is known as the offspring.

There are two basic methods of reproduction. An organism can give rise to another organism by the method of asexual or sexual reproduction.

During asexual reproduction, identical copies of the parent organism are made. During sexual reproduction, two organisms reproduce to produce non-identical offsprings.
