Q: Answer the following question given this paragraph: Birds have a large brain relative to the size of their body. Not surprisingly, the part of the brain that controls flight is the most developed part. The large brain size of birds is also reflected by their high level of intelligence and complex behavior. In fact, birds such as crows and ravens may be more intelligent than many mammals. They are smart enough to use objects such as twigs for tools. They also demonstrate planning and cooperation. Most birds have a poor sense of smell, but they make up for it with their excellent sense of sight. Predatory birds have especially good eyesight. Hawks, for example, have vision that is eight times sharper than human vision. Q: Not surprisingly, what is the function of the most developed part of a bird's brain? A:

OPTIONS:
- controlling digestion
- controlling breeding
- controlling thought
- controlling flight

A: controlling flight

input: OPTIONS:
- primitive respiratory
- autonomic nerous system
- photosynthetic
- water-based circulatory Now, answer this question: Answer the following question given this paragraph: 15.5 Echinoderms and Chordates Echinoderms are deuterostome marine organisms. This phylum of animals bear a calcareous endoskeleton composed of ossicles covered by a spiny skin. Echinoderms possess a water-based circulatory system. The madreporite is the point of entry and exit for water for the water vascular system. The characteristic features of Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the. Q: What kind of system do echinoderms possess? A:
A:
output: water-based circulatory

Answer the following question given this paragraph: A lymphocyte is the type of white blood cell involved in an immune system response. You can see what a lymphocyte looks like, greatly magnified, in Figure below . Lymphocytes make up about one quarter of all white blood cells, but there are trillions of them in the human body. Usually, fewer than half of the body's lymphocytes are in the blood. The majority are in the lymph, lymph nodes, and lymph organs. Q: A lymphocyte is the type of which cell involved in an immune system response? A:

OPTIONS:
- red blood cell
- white immunity cell
- white brain cell
- white blood cell

Answer: white blood cell

Problem: OPTIONS:
- Ultramafic lava
- Intermediate lava
- Felsic lava
- mafic
Q: Answer the following question given this paragraph: Felsic lavas are more viscous and erupt explosively or do not erupt. Mafic lavas are less viscous and erupt effusively. Q: Which type of lava lavas are less viscous and erupt effusively? A:
Answer: mafic

Problem:OPTIONS:
- human fibers
- use fibers
- job fibers
- muscle fibers

Answer the following question given this paragraph: The muscular system consists of all the muscles of the body. Muscles are organs composed mainly of muscle cells, which are also called muscle fibers . Each muscle fiber is a very long, thin cell that can do something no other cell can do. It can contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out. There are three types of muscle tissues in the human body: cardiac, smooth, and skeletal muscle tissues. They are shown in Figure below and described below. Q: What are muscle cells in the muscles called? A:
****
A: muscle fibers

Problem:OPTIONS:
- pole induction
