The ability of your body's immune system to distinguish between your cells
KatRina [158]

Answer:

<em>The correct option is cell surface markers.</em>

Explanation:

The immune cells of our body detect foreign particles and generate responses so that our body can get rid of them. The foreign particles are often termed as antigens.

The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.

28) The graph below shows how the activity of an enzyme changes at different temperatures.
puteri [66]

Answer:

d) The enzyme changes shape and can no longer speed up the reaction

Explanation:

Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.

Arteries carry oxygenated blood away from the heart and typically have ________________ blood pressure. Veins carry deoxygenated
KatRina [158]
The correct answer is high, low.

Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.

Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.

Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.
