Plasma cells are designed to churn out Antibodies. These are proteins that have a variable region which is complementary ( perfect shape fit) for the virus' antigen and can therefore bind to the antigen, making the virus harmless or tagging it to be consumed by a phagocyte.

Answer:
The correct answer is - they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria
Explanation:
Red blood cells are considered as the cells, carry oxygen with the help of hemoglobin protein present in it to the various parts of the body from the lungs and carry CO2 back to the lungs.
These cells are different from the normal cell as they do not participate in the protein synthesis due to the fact that they lack various cell organelle and cell components required. Nucleus and DNA are major components or organelle missing from these cells. In addition to these two, endoplasmic reticulum and mitochondria also missing from RBCs.
Answer:
The answer is: Classical Conditioning.
Explanation:
- According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
- A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
- A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
- In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
- But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).

Weather is the day-to-day changes in the atmospheric conditions of regions. Weather parameters are usually temperatures, humidity, rainfall, air pressure, and etcetera. These vary greatly every so often on a daily basis. Climate, on the other hand is categories into arctic, subarctic, subterranean, Mediterranean, temperature, equatorial, and etcetera.
Explanation:
When weather is studied for a long time, such as for over 30 years, general weather patterns can be discerned that will determine the climate of the region. These general weather patterns over a region will make up its climate. Climate does not change considerably. Therefore the climate of a region remains steady. If the climate of a region changes it does so ever so slightly over millennia and would change because of phenomena like earth’s tectonic plate movements, space phenomenons, and human activities.
