Electromagnetic waves travel from the sun to Earth across space and provide virtually all the energy that supports life on our planet. Many other sources of electromagnetic waves depend on technology. Radio waves, microwaves, and X rays are examples. We use these electromagnetic waves for communications, cooking, medicine, and many other purposes. Q: What is the most important source of electromagnetic waves on earth? A:
A:
output: the sun

Answer the following question given this paragraph: They live mutualistically with other organisms. Mutualistic fungi live harmlessly with other living organisms.

OPTIONS:
- neutral
- harmful
- abnormal
- beneficial

Answer: beneficial

Problem: OPTIONS:

Q: Answer the following question given this paragraph: Once we reach neon, a noble gas, all of the 2p orbitals will be completely full. Neon has a configuration of 1s 2 2s 2 2p 6 . Any further electrons will need to go in the next highest energy orbital, which would be the 3s orbital. Q: Neon is an example of what kind of gas? A:
Answer: noble

Problem:OPTIONS:
- death
- response
- birth
- development

Answer the following question given this paragraph: Chordates are defined by a set of four characteristics that are shared by these animals at some point during their development. In some chordates, all four traits are present in the adult animal and serve important functions. However, in many chordates, including humans, some traits are present only during the embryonic stage. After that, these traits may disappear. Q: Chordates are defined by a set of four characteristics that are shared by these animals at some point during their? A:
****
A: development

Answer the following question given this paragraph: Starches are complex carbohydrates. They are polymers of glucose. They consist of hundreds of glucose monomers bonded together. Plants make starch to store extra sugars. Consumers get starch from plants. Common sources of starch in the human diet are pictured in Figure below . Our digestive system breaks down starch to simple sugars, which our cells use for energy. Q: Our digestive system breaks down starch to what? A:
OPTIONS:
- Salts
- Waste
- pattern sugars
- simple sugars
simple sugars

Answer the following question given this paragraph: Two identical diploid cells result from spermatogonia mitosis. One of these cells remains a spermatogonium, and the other becomes a primary spermatocyte, the next stage in the process of spermatogenesis. As in mitosis, DNA is replicated in a primary spermatocyte, and the cell undergoes cell division to produce two cells with identical chromosomes. Each of these is a secondary spermatocyte. Now a second round of cell division occurs in both of the secondary spermatocytes, separating the chromosome pairs. This second meiotic division results in a total of four cells with only half of the number of chromosomes. Each of these new cells is a spermatid. Although haploid, early spermatids look very similar to cells in the earlier stages of spermatogenesis, with a round shape, central nucleus, and large amount of cytoplasm. A process called spermiogenesis transforms these early spermatids, reducing the cytoplasm, and beginning the formation of the parts of a true sperm. The fifth stage of germ cell formationspermatozoa, or formed spermis the end result of this process, which occurs in the portion of the tubule nearest the lumen. Eventually, the sperm are released into the lumen and are moved along a series of ducts in the testis toward a structure called the epididymis for the next step of sperm maturation. Q: During mitosis what is replicated in the primary spermatocyte? A:
OPTIONS:
- mitochondira
- oocyte
- rna
- dna

Answer:
dna
