Answer the following question given this paragraph: The basic building blocks of the human body are cells. Human cells are organized into tissues, tissues are organized into organs, and organs are organized into organ systems. Q: What are the basic building blocks of the human body? Choices: - proteins - minerals - vitamins - cells A:
cells

Answer the following question given this paragraph: Plants are the primary producers in terrestrial biomes. They make food for themselves and other organisms by photosynthesis. The major plants in a given biome, in turn, help determine the types of animals and other organisms that can live there. Q: What are the primary producers in terrestrial biomes? Choices: - soil - gases - animals - plants A:
(Answer)
plants
Ques: Answer the following question given this paragraph: Internal Fertilization Internal fertilization occurs most often in terrestrial animals, although some aquatic animals also use this method. Internal fertilization may occur by the male directly depositing sperm in the female during mating. It may also occur by the male depositing sperm in the environment, usually in a protective structure, which a female picks up to deposit the sperm in her reproductive tract. There are three ways that offspring are produced following internal fertilization. In oviparity, fertilized eggs are laid outside the female's body and develop there, receiving nourishment from the yolk that is a part of the egg (Figure 18.7a). This occurs in some bony fish, some reptiles, a few cartilaginous fish, some amphibians, a few mammals, and all birds. Most non-avian reptiles and insects produce leathery eggs, while birds and some turtles produce eggs with high concentrations of calcium carbonate in the shell, making them hard. Chicken eggs are an example of a hard shell. The eggs of the egg-laying mammals such as the platypus and echidna are leathery. In ovoviparity, fertilized eggs are retained in the female, and the embryo obtains its nourishment from the egg's yolk. The eggs are retained in the female's body until they hatch inside of her, or she lays the eggs right before they hatch. This process helps protect the eggs until hatching. This occurs in some bony fish (like the platyfish Xiphophorus maculatus, Figure 18.7b), some sharks, lizards, some snakes (garter snake Thamnophis sirtalis), some vipers, and some invertebrate animals (Madagascar hissing cockroach Gromphadorhina portentosa). In viviparity the young are born alive. They obtain their nourishment from the female and are born in varying states of maturity. This occurs in most mammals (Figure 18.7c), some cartilaginous fish, and a few reptiles. Q: When a male directly deposits sperm in a female during mating, this is considered what type of fertilization? Choices: - dual - mechanical - external - internal A:
Ans: internal

Answer the following question given this paragraph: In the digestive system, food is digested and its nutrients are absorbed by the blood for transport around the body. The blood is part of the cardiovascular system. Q: Nutrients from food are absorbed by the blood for transport around the body as part of what system? Choices: - growth - respiratory - circulatory - digestive A:
(A).
digestive
Ques:Answer the following question given this paragraph: every organism uses to power its metabolism. In brief, the energy of sunlight is captured and used to energize electrons, which are then stored in the covalent bonds of sugar molecules. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 8.2). Because they use light to manufacture their own food, they are called photoautotrophs (literally, "self-feeders using light"). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs ("other feeders"), because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight's energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs. Q: Photoautotrophs use what energy source to self-manufacture their own food? Choices: - water - chlorophyll - air - light A:

Ans:light
Question: Answer the following question given this paragraph: 33.3 Homeostasis Homeostasis is a dynamic equilibrium that is maintained in body tissues and organs. It is dynamic because it is constantly adjusting to the changes that the systems encounter. It is in equilibrium because body functions are kept within a normal range, with some fluctuations around a set point for the processes. Q: What is the term for a dynamic equilibrium that is maintained in body tissues and organs? Choices: - homogeneity - metabolism - dormancy - homeostasis A:
Answer:
homeostasis
