How are blood cells and stomach cells similar?
• Both secrete enzymes.
• Both help maintain homeostasis.
• Both send signals in the body.
• Both help with digestion.
The correct answer is (c) maintain homeostasis. Both blood cells and stomach cells play a role in maintaining the body's internal environment and ensuring that it stays balanced and stable. However, they achieve this through different mechanisms, with blood cells transporting oxygen and nutrients and stomach cells secreting enzymes for digestion. While blood cells do require iron for the production of hemoglobin, which is involved in oxygen transport, this is not a characteristic shared with stomach cells.
An eye doctor shines a bright light into a patient's eye. In one to two sentences, explain how the patient's brain perceives the bright light.
The bright light stimulates photoreceptor cells in the retina of the eye, which then send electrical signals through the optic nerve to the brain. The brain then processes these signals and translates them into the perception of a bright light.
Blood cells and stomach cells are similar in that they both help with digestion. To understand how they help with digestion, we can break down the comparison:
First, let's look at blood cells. There are different types of blood cells, namely red blood cells, white blood cells, and platelets. Red blood cells carry oxygen from the lungs to the body's tissues and remove carbon dioxide waste. While white blood cells help fight infections and foreign substances in the body. Platelets play a role in blood clotting to prevent excessive bleeding.
On the other hand, stomach cells are specialized cells found in the lining of the stomach. The stomach secretes digestive enzymes such as pepsin and hydrochloric acid. These enzymes aid in the breakdown of food molecules into smaller, more absorbable particles. The stomach cells also produce mucus that protects the stomach lining from these digestive juices.
Comparing the two, both blood cells and stomach cells contribute to the process of digestion. Blood cells transport nutrients and oxygen to the stomach cells, ensuring they receive the necessary oxygen and nutrients for carrying out their functions effectively. Conversely, stomach cells secrete enzymes that help break down food particles, aiding in digestion.
Therefore, the correct answer to how blood cells and stomach cells are similar in this context is "Both help with digestion."
