bixtya [17]3 years ago
7 0

Primary immune response is response that appears as a result of the first exposure to antigen. On the other side, secondary immune response is the one that occurs when the organism is exposed to the same antigen for the second, third, fourth time. Responding cells of the first immune response are naïve B and T cells (lymphocytes), while responding cells of the secondary immune response are memory T cells. Secondary immune response is much faster (takes shorter time to establish immunity) and amount of antibodies is higher than in primary immune response.

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Scilla [17]

Answer:

Hope the below helps!

Explanation:

Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.

Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.

I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
