I love questions like this! Science is so cool! So, strangely enough, a vaccine is a very weak bacteria. If the bacteria was strong, your immune system couldn't defend. Because its a weak cell, your immune cells can fight it. Did you know that you have a special cell inside you? This cell remembers every bacteria that comes to your body. Because you had very weak, damaged bacteria in you, (measles bacteria), you can remember it, and grow strong against it. Then, when germs try to enter your body, your immune system is right there to defend it. Everytime the bacteria of Measles tries to enter, your immune system is extra strong because it remembers it. Isn't that cool?

Answer:
C
Explanation:
Opportunist are organisms that are found naturally in other living organism and only cause disease in the organism when its immune system is compromised for example HIV virus lowers immune system strength by reducing the amount of the CD4⁺ cells available thereby exposing the organism to attack from opportunistic organism such <em>Staphylococcus aureus. </em>The opinion that supports the statement is S.aureus is found in the nasal passages of many healthy people.
Answer:
The outermost shell of a terrestrial planet is referred to as "crust." The Earth's crust is separated into two types: continental crust, which is older and thicker, and oceanic crust, which is younger and denser. Plate tectonics influences the dynamic geology of the Earth's crust. The outermost shell of a terrestrial planet is referred to as "crust."
The mantle is the layer immediately beneath the sima. With a thickness of 1800 miles, it is the Earth's thickest layer. The mantle is made up of extremely hot and thick rock. Under the weight of a huge load, this layer of granite even flows like asphalt. The flow is caused by large temperature differences between the mantle's bottom and top. The movement of the Earth's plates is due to the movement of the mantle! The mantle's temperature ranges from 1600 degrees Fahrenheit near the top to about 4000 degrees Fahrenheit near the bottom!
