Answer:

C. causes cell lysis

Explanation:

The slow release of the bacteriophage progeny from a bacterial host cell causes bacterial cell lysis and further kills the host cell which is the bacteria, this results to the liberation of progeny viruses which then infect new bacterial cells.

Only a type of bacteriophage called the filamentous bacteriophage reproduces without killing the bacterial host cell.  The filamentous phages infect majorly gram negative bacteria.

6. Which of the following organelles are not involved in protein synthesis?
Tomtit [17]

Answer:

d. smooth endoplasmic reticulum

Explanation:

Organelles are structures found in inside the cell which carries out a specific function. Types of organelles include endoplasmic reticulum, Golgi body, ribosomes, nucleus etc. The function in the question is protein synthesis.

Ribosomes are the sites of protein synthesis in the cell of living organisms.

- The nucleus is involved in the synthesis of protein because it directs all the cellular processes in a cell including protein synthesis.

- Rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum whose surface is attached to by ribosomes, hence, giving it its rough surface. Since ribosomes (organelle for protein synthesis) are attached to the RER, the RER are involved in protein synthesis.

- Golgi bodies are organelles that functions to package, process and sorted the proteins produced in the ribosomes.

- The smooth endoplasmic reticulum (SER) are NOT involved in the synthesis of protein because they have no ribosomes attached to their surface. Instead, they are involved in lipid synthesis.

Which of the following starts to break down as soon as they enter the mouth?
MissTica

The answer is carbohydrates.

Food  in  the mouth is moistened and lubricated  with saliva. Saliva contains an enzyme called salivary amylase. 

Salivary amylase is an enzyme that breaks down complex carbohydrates molecules into simple or smaller carbohydrate molecules  called maltose. The enzyme acts on carbohydrates in the mouth, initiating the process of digestion.

Salivary amylase  is made by the salivary glands in the mouth. Maltose is later converted to glucose in the small intestine by another type of amylase called pancreatic amylase.
