Q: Answer the following question given this paragraph: The skin has multiple roles in the body. Many of these roles are related to homeostasis. The skin's main functions are preventing water loss from the body and serving as a barrier to the entry of microorganisms. In addition, melanin in the skin blocks UV light and protects deeper layers from its damaging effects. Q: The skin plays an important role in preventing the escape of what commonly found liquid from the body? Choices: - hormones - stomach acid - urine - water A:
A: water

Q: Answer the following question given this paragraph: Looking at different types of competition, ecologists developed the competitive exclusion principle . The principle states that species less suited to compete for resources will either adapt, move from the area, or die out. In order for two species within the same area to coexist, they may adapt by developing different specializations. This is known as character displacement . An example of character displacement is when different birds adapt to eating different types of food. They can develop different types of bills, like Darwin's Finches ( Figure below ). Therefore, competition for resources within and between species plays an important role in evolution through natural selection . Q: What is the concept by which two species within the same area to coexist by adapting by developing different specializations? Choices: - character development - feature displacement - character concept - character displacement A:
A: character displacement

Q: Answer the following question given this paragraph: Some enzymes require the presence of a non-protein molecule called a cofactor in order to function properly. Cofactors can be inorganic metal ions or small organic molecules. Many vitamins, such as B vitamins, act as cofactors. Some metal ions which function as cofactors for various enzymes include zinc, magnesium, potassium, and iron. Q: Some enzymes require the presence of a non-protein molecule to function properly. what is that molecule called? Choices: - substrate - coenzymes - prothetic - cofactor A:
A: cofactor
