Answer the following question given this paragraph: Hormones control many cell activities, so they are very important for homeostasis. But what controls the hormones themselves? Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops . Negative feedback keeps the concentration of a hormone within a narrow range. Q: Because they control many cell activities - as well as being controlled by feedback mechanisms - what substances are very important for homeostasis? A:
OPTIONS:
- acids
- proteins
- enzymes
- hormones

Answer: hormones

Question: Answer the following question given this paragraph: Because the hydroxyl radical has an unpaired electron, it is highly reactive. (This is true of any substance with unpaired electrons, known as a free radical. ) This hydroxyl radical can react with all kinds of biological molecules (DNA, proteins, enzymes, and so on), causing damage to the molecules and disrupting physiological processes. Examples of direct and indirect damage are shown in Figure 21.32. Q: The hydroxyl radical is highly reactive because it has what? A:
OPTIONS:
- unpaired neutron
- paired proton
- paired electron
- unpaired electron
Answer: unpaired electron

input with options: Answer the following question given this paragraph: The dermis is the layer of skin directly under the epidermis. It is made of a tough connective tissue. The dermis contains hair follicles, sweat glands, oil glands, and blood vessels ( Figure above ). It also holds many nerve endings that give you your sense of touch, pressure, heat, and pain. Q: What layer of skin is directly under the epidermis? A:
OPTIONS:
- the aponeurosis
- hypodermis
- sweat glands
- the dermis
output: the dermis

Q: Answer the following question given this paragraph: Immunity can also be caused by vaccination. Vaccination is the process of exposing a person to a pathogen on purpose in order to develop immunity. In vaccination, a modified pathogen is usually injected under the skin by a shot. Only part of the pathogen is injected, or a weak or dead pathogen is used. It sounds dangerous, but the shot prepares your body for fighting the pathogen without causing the actual illness. Vaccination triggers an immune response against the injected antigen. The body prepares "memory" cells for use at a later time, in case the antigen is ever encountered again. Essentially, a vaccine imitates an infection, triggering an immune response, without making a person sick. Q: What is the term for the process of exposing a person to a pathogen on purpose in order to develop immunity? A:

OPTIONS:
- evacuation
- ramping
- priming
- vaccination

A: vaccination

Answer the following question given this paragraph: Many sponges live on coral reefs, like the one in Figure below . Reef sponges typically have symbiotic relationships with other reef species. For example, the sponges provide shelter for algae, shrimp, and crabs. In return, they get nutrients from the metabolism of the organisms they shelter. Q: Reef sponges typically have what type of beneficial relationships with other reef species? A:
OPTIONS:
- parasitic
- microbes
- mutual
- symbiotic
symbiotic
