Answer the following question given this paragraph: Note that in fragmentation, there is generally a noticeable difference in the size of the individuals, whereas in fission, two individuals of approximate size are formed. Parthenogenesis Parthenogenesis is a form of asexual reproduction where an egg develops into a complete individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process and the species. Parthenogenesis occurs in invertebrates such as water flees, rotifers, aphids, stick insects, some ants, wasps, and bees. Bees use parthenogenesis to produce haploid males (drones) and diploid females (workers). If an egg is fertilized, a queen is produced. The queen bee controls the reproduction of the hive bees to regulate the type of bee produced. Some vertebrate animalssuch as certain reptiles, amphibians, and fishalso reproduce through parthenogenesis. Although more common in plants, parthenogenesis has been observed in animal species that were segregated by sex in terrestrial or marine zoos. Two female Komodo dragons, a hammerhead shark, and a blacktop shark have produced parthenogenic young when the females have been isolated from males. Q: In which kind of animals does parthenogenesis occur? Choices: - tissues - mammals - species - invertebrates A:
invertebrates
Answer the following question given this paragraph: Mutations that occur in gametes can be passed on to offspring. An offspring that inherits a mutation in a gamete will have the mutation in all of its cells. Q: An offspring that inherits a mutation in a gamete will have the mutation in all of its? Choices: - seeds - proteins - eggs - cells A:
cells
Q: Answer the following question given this paragraph: Ash and particles shoot many kilometers into the sky. The material may form a mushroom cloud, just like a nuclear explosion. Hot fragments of rock, called pyroclasts , fly up into the air at very high speeds. The pyroclasts cool in the atmosphere. Some ash may stay in the atmosphere for years. The ash may block out sunlight. This changes weather patterns and affects the temperature of the Earth. For a year or two after a large eruption, sunsets may be especially beautiful worldwide. Q: What are hot fragments of rock called? Choices: - obsidian - magma - shards - pyroclasts A:
A: pyroclasts
Question: Answer the following question given this paragraph: An electric transformer connects two circuits with an iron core that becomes an electromagnet. Q: An electric transformer connects two circuits with an iron core that becomes what? Choices: - inductive - radioactive - actuator - electromagnet A:
Answer: electromagnet
*Question*
Answer the following question given this paragraph: Why do charges flow in an electric current? The answer has to do with electric potential energy. Potential energy is stored energy that an object has due to its position or shape. An electric charge has potential energy because of its position in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where their potential energy is lower. This is similar to water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What is the scientific term for stored energy an object has due to its position or shape? Choices: - repeat energy - mechanical energy - new energy - potential energy A:
**Answer**
potential energy
Answer the following question given this paragraph: The cell wall is a rigid layer that surrounds the cell membrane of a plant cell. It's made mainly of the complex carbohydrate called cellulose. The cell wall supports and protects the cell. The cell wall isn't solid like a brick wall. It has tiny holes in it called pores. The pores let water, nutrients, and other substances move into and out of the cell. Q: What rigid layer surrounds the cell membrane of a plant cell? Choices: - bark - epidermis - cuticle - cell wall A:
cell wall
