correct answer is 95%
Answer:
Control group
Explanation:
In an experiment, the group which receives the treatment (in this case injection of actual drug) is known as experimental group because the experiment is being conducted on it. While on the other hand the group which do not receive the treatment is known as control group. The results obtained from the experimental group are compared with the control group to determine the effectiveness of the treatment.
Which of the following best describes an example of a specific internal response to harmful bacteria?
Skin serves as a physical barrier that prevents bacteria from entering the body.
Saliva contains enzymes that destroy bacteria and prevent infection.
Bacterial infection causes the release of histamine, which leads to inflammation and swelling.
Antigens trigger the production of antibodies, which mark bacteria for destruction.
Answer:
Antigens trigger the production of antibodies, which mark bacteria for destruction.
Explanation:
The question is talking about internal response to bacteria so we have to look at what happens inside the body pertaining to bacterial infection, so the answer is "Antigens trigger the production of antibodies, which mark bacteria for destruction".
Answer:
A .....the skin is the bodies first line of defense
Explanation:
The first line of defence is non-specific and aims to stop microbes from entering the body.

Green plants are green because of the pigment chlorophyll, which absorbs most wavelengths of light except for green. The wavelength of light being reflected or transmitted by green plants is in the range of approximately 500-570 nanometers.
Green plants appear green because they contain a pigment called chlorophyll, which absorbs most wavelengths of light except for green. This means that green light is reflected or transmitted by the plant, which is then detected by our eyes as the color green.
The wavelength of light that is being reflected or transmitted by green plants is in the range of approximately 500-570 nanometers. This is within the visible light spectrum, which ranges from about 400 to 700 nanometers.

Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
