Oceanic Crust is the thinnest
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

Answer;
The above statement is true
Explanation;
-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
Hello!
While they do not penetrate very far into the body, they can indeed get through.
Commonly, materials that emit alpha, beta or gamma radiation get into the body alone or with other materials which have may become contaminated.
Here are some ways these could get in:
Through breathing; It could be in the air or mixed with dust, which is in the air.
Drinking; It disolves in water, meaning the material could get in your body without you knowing.
In the soil; If soil is contaminated, and plants grow in that soil, you will get a small ammount of alpha and beta particles.
Lastly, animals; Plants and animals can become contaminated, the particles coud be taken in through consumtion.
Hope this helps!
Have a great day!
