Answer the following question given this paragraph: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. Q: What single-celled organism can be either a predator, decomposer, herbivore, or parasite in the food chain? Choices: - vertebrates - mites - Diatoms - protozoa A:
(Answer)
protozoa
Ques: Answer the following question given this paragraph: The mother's mammary glands go through changes during the third trimester to prepare for lactation and breastfeeding. When the baby begins suckling at the breast, signals are sent to the hypothalamus causing the release of prolactin from the anterior pituitary. Prolactin causes the mammary glands to produce milk.

The milk contains nutrients for the baby's development and growth as well as immunoglobulins to protect the child from bacterial and viral infections. Q: Human mammary glands can produce what substance, which can be used to feed children? Choices: - edema - urea - sperm - milk A:
Ans: milk
