No as lysosomes also can be found in plant cells and other organisms.
Answer:
Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and amplifies hydrogeological risk, such as landslides or floods
Explanation:
Answer:
The correct answer is B. The virus can infect the host.
Explanation:
- As the host and the virus both remain in the agar plate, the virus is capable of infecting the host cells.
- The host cell multiplies and grows by utilising the nutrient from the agar medium.
- After the virus particles infect the host, they replicate inside the host and produce new progeny virions which get released out of the host cell by killing it.
- The newly formed virions infect other host cells and the process continues.
- The killing of the host cells by the viruses result in the generation of clear zones on the agar plate which is also known as the zone of exclusion.
- In the zone of exclusion region, the host cells have been killed by the viruses.
<u>T cells lymphocytes </u>are a type of white blood cell that actively target and destroy infected cells via the production of antibodies.
The functions of proteins include:
- They transport oxygen in the blood of vertebrates.
- They play a key role in moving materials within cells.
- They help the body recognize and destroy foreign microbes and cancer cells.
- They catalyze chemical reactions.
<h3>Functions of proteins</h3>
Proteins are macromolecules that helps in the maintenance of metabolic activities and repair of worn out tissues of the body.
There are several functions of proteins which has helped in it's classification. The different types of Protein found in the body are:
- Antibodies: These are proteins that function to recognize and destroy foreign microbes and cancer cells.
- Enzymes: These are proteins that catalyze chemical reactions in the body.
- Transport proteins: They play a key role in moving materials within cells.
- Haemoglobin: These are blood proteins that transport oxygen in the blood of vertebrates.
