nignag [31]

Answer:

See explanation below.

Explanation:

Viruses cause problems when they enter the body and begin to grow and reproduce. They can have byproducts that are harmful. Strep throat for example gives off substances that cause inflammation in the throat. Some viruses can cause serious issues such as nerve damage, like polio. So the immune system works to recognize and deal with cells that might cause harm.

The first time that a particular virus moves in and attacks the body, the immune system - and the white blood cells - might be slow to recognize the issue and take some time to swing into action. But the next time that particular germs shows up, the body is ready for it and reacts much more quickly. The body us designed this way so that harm by invading germs can be halted or minimized.

Hope this helps! Have an awesome day!! :-)

Explain how tomatoes grown and typically prepared as a dish below??<br><br>need it noww!༼ つ ◕◡◕ ༽つ​
grandymaker [24]
Tomatoes are commonly grown from seedlings started indoors that are later transplanted into the garden. Tomato seeds are commonly planted indoors as early as 8 to 6 weeks before the average date of the last spring frost. Tomato seedlings are usually transplanted into the garden 1 to 3 weeks after the last frost. Wash tomatoes under cool running water.

Slice an "X" on the bottom of each tomato with a small utility knife. In a large saucepan bring water to a rolling boil. Fill a large mixing bowl with ice cold water. With a large spoon, place tomatoes in boiling water for 30 seconds to loosen skin. Remove tomatoes after 30 seconds, place directly into cold water to stop the cooking process. Core the tomatoes by removing the stem with a paring knife. Peel away the skin, being careful not to injure the flesh of the tomatoes.
