input: OPTIONS:
- at the cerebrum
- at the medulla oblongata
- at the meninges
- at the pons Now, answer this question: Answer the following question given this paragraph: Secondary Vesicles The brain continues to develop, and the vesicles differentiate further (see Figure 13.3b). The three primary vesicles become five secondary vesicles. The prosencephalon enlarges into two new vesicles called the telencephalon and the diencephalon. The telecephalon will become the cerebrum. The diencephalon gives rise to several adult structures; two that will be important are the thalamus and the hypothalamus. In the embryonic diencephalon, a structure known as the eye cup develops, which will eventually become the retina, the nervous tissue of the eye called the retina. This is a rare example of nervous tissue developing as part of the CNS structures in the embryo, but becoming a peripheral structure in the fully formed nervous system. The mesencephalon does not differentiate into any finer divisions. The midbrain is an established region of the brain at the primary vesicle stage of development and remains that way. The rest of the brain develops around it and constitutes a large percentage of the mass of the brain. Dividing the brain into forebrain, midbrain, and hindbrain is useful in considering its developmental pattern, but the midbrain is a small proportion of the entire brain, relatively speaking. The rhombencephalon develops into the metencephalon and myelencephalon. The metencephalon corresponds to the adult structure known as the pons and also gives rise to the cerebellum. The cerebellum (from the Latin meaning "little brain") accounts for about 10 percent of the mass of the brain and is an important structure in itself. The most significant connection between the cerebellum and the rest of the brain is at the pons, because the pons and cerebellum develop out of the same vesicle. The myelencephalon corresponds to the adult structure known as the medulla oblongata. The structures that come. Q: Where is the most significant connection between the cerebellum and the rest of the brain? A:
A:
output: at the pons

Answer the following question given this paragraph: Opaque matter is matter that does not let any light pass through it. Matter may be opaque because it absorbs light, reflects light, or does both. Examples of opaque objects are solid wooden doors and glass mirrors. A wooden door absorbs most of the light that strikes it and reflects just a few wavelengths of visible light. A mirror, which is a sheet of glass with a shiny metal coating on the back, reflects all the light that strikes it. Q: What is the term for matter that does not let any light pass through it, whether it absorbs light, reflects light, or does both? A:

OPTIONS:
- devoid
- obscene
- artificial
- opaque

Answer: opaque

Problem: OPTIONS:
- factor synthesis
- light synthesis
- gas synthesis
- protein synthesis
Q: Answer the following question given this paragraph: The process in which cells make proteins is called protein synthesis . It actually consists of two processes: transcription and translation . Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein. Q: What is the process in which cells make proteins called? A:
Answer: protein synthesis

Problem:OPTIONS:
- cooperative
- bilateral
- parasitic
- commensalism

Answer the following question given this paragraph: 24.4 | Fungal Parasites and Pathogens By the end of this section, you will be able to: Describe fungal parasites and pathogens of plants Describe the different types of fungal infections in humans Explain why antifungal therapy is hampered by the similarity between fungal and animal cells Parasitism describes a symbiotic relationship in which one member of the association benefits at the expense of the other. Both parasites and pathogens harm the host; however, the pathogen causes a disease, whereas the parasite usually does not. Commensalism occurs when one member benefits without affecting the other. Q: What type of relationship occurs between organisms when one member benefits without affecting the other? A:
****
A: commensalism

Answer the following question given this paragraph: Early in the development of a human fetus, the skeleton is made entirely of cartilage. The relatively soft cartilage gradually turns into hard bone through ossification . This is a process in which mineral deposits replace cartilage. As shown in Figure below , ossification of long bones, which are found in the arms and legs, begins at the center of the bones and continues toward the ends. By birth, several areas of cartilage remain in the skeleton, including the ends of the long bones. This cartilage grows as the long bones grow, so the bones can keep increasing in length during childhood. Q: While still an early fetus, what is the skeleton made of? A:
OPTIONS:
- ligament
- membrane
- gel
- cartilage
cartilage

Answer the following question given this paragraph: Perhaps the most familiar example of corrosion is the formation of rust on iron. Iron will rust when it is exposed to oxygen and water. The main steps in the rusting of iron appear to involve the following (Figure 17.17). Once exposed to the atmosphere, iron rapidly oxidizes. anode: Fe(s) Fe 2+(aq) + 2e . Q: Iron will do what when it is exposed to oxygen and water? A:
OPTIONS:
- become hot
- expand
- contract
- rust

Answer:
rust
