Question: Q: What structures on the gastrodermal cells keep the contents of the gastrovascular cavity agitated and help distribute nutrients?   Read this paragraph and choose the correct option from the provided answers:     Choices:  - telomeres  - sporangia  - nucleus  - flagella   A:
flagella
Q: Tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume are all types of what kind of measurement?   Read this paragraph and choose the correct option from the provided answers:  39.2 Gas Exchange across Respiratory Surfaces The lungs can hold a large volume of air, but they are not usually filled to maximal capacity. Lung volume measurements include tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume. The sum of these equals the total lung capacity. Gas movement into or out of the lungs is dependent on the pressure of the gas. Air is a mixture of gases; therefore, the partial pressure of each gas can be calculated to determine how the gas will flow in the lung. The difference between the partial pressure of the gas in the air drives oxygen into the tissues and carbon dioxide out of the body.   Choices:  - respiratory volume  - emitted volume  - breathing volume  - lung volume   A:
lung volume
Q: Q: The golgi apparatus works like a mail room by receiving and sending what?   Read this paragraph and choose the correct option from the provided answers:  The Golgi apparatus works like a mail room. The Golgi apparatus receives proteins from the rough ER and puts "shipping addresses" on them. The Golgi then packages the proteins into vesicles and sends them to the right place in the cell or to the cell membrane. Some of these proteins are secreted from the cell (they exit the cell); others are placed into the cell membrane.   Choices:  - acids  - particles  - enzymes  - proteins   A:
A: proteins
Question: Q: What type of flowers offer no reward, such as nectar, to a male wasp?   Read this paragraph and choose the correct option from the provided answers:     Choices:  - vines  - perennials  - roses  - ophrys   A:
Answer: ophrys

Q: In studying energy, what term do scientists use to refer to the matter and its environment involved in energy transfers?   Read this paragraph and choose the correct option from the provided answers:  6.3 The Laws of Thermodynamics In studying energy, scientists use the term “system” to refer to the matter and its environment involved in energy transfers. Everything outside of the system is called the surroundings. Single cells are biological systems. Systems can be thought of as having a certain amount of order. It takes energy to make a system more ordered. The more ordered a system is, the lower its entropy. Entropy is a measure of the disorder of a system. As a system becomes more disordered, the lower its energy and the higher its entropy become. A series of laws, called the laws of thermodynamics, describe the properties and processes of energy transfer. The first law states that the total amount of energy in the universe is constant. This means that energy can’t be created or destroyed, only transferred or transformed. The second law of thermodynamics states that every energy transfer involves some loss of energy in an unusable form, such as heat energy, resulting in a more disordered system. In other words, no energy transfer is completely efficient and tends toward disorder.   Choices:  - molecule  - ecosystem  - world  - system   A:
**Answer**
system

Q: What type of organisms do not need blood?   Read this paragraph and choose the correct option from the provided answers:  Single-celled organisms do not need blood. They obtain nutrients directly from and excrete wastes directly into their environment. The human organism cannot do that. Our large, complex bodies need blood to deliver nutrients to and remove wastes from our trillions of cells. The heart pumps blood throughout the body in a network of blood vessels. Together, these three components—blood, heart, and vessels—makes up the cardiovascular system. This chapter focuses on the medium of transport: blood.   Choices:  - cold-blooded  - vertebrate  - marine  - single-celled   A:
(Answer)

Answer: single-celled
