Answer:
antigens
Explanation:
Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
The ratio is 3:4; 3 will be purple and 1 white. 25% is PP, 50% is Pp, and 25% is pp.
Cool air over any pole will either cause a voluntary crash on the floor/ collapse, but it all depends on the strength of its placement in the ground. A weak placement could easily make it collapse, or it could stay still (with perhaps a flag waving in the direction of the wind, on top) of kept firmly onto the ground.
Answer:
R=v^2/p
Explanation:
The Ohm's law is a relation between voltage, current and resistance:
If you dont know the current and know the power circulating in the circuit, you can use the relation between power, voltage and resistance:
R=v^2/p
