Answer:
The name of the innate immune component is MEMBRANE ATTACK COMPLEX.
Explanation:
The membrane attack complex is a type of structure that is usually formed on the surface of the cell membrane of invading pathogens due to the activation of the immune system. Membrane attack complex is also known as terminal complement complex. Individuals that lack this immune component due to mutations usually experience recurrent infections.
It occurs during Anaphase II, Telophase II, and Cytokinesis, when the sister chromatids separate so that there is 1 allele per gamete.
Answer:
Argon
Explanation:
Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.
