Q: Asci are used by mycelia for what kind of reproduction? Read this paragraph and choose the correct option from the provided answers: hyphae divided by perforated septa, allowing streaming of cytoplasm from one cell to the other. Conidia and asci, which are used respectively for asexual and sexual reproductions, are usually separated from the vegetative hyphae by blocked (non-perforated) septa. Asexual reproduction is frequent and involves the production of conidiophores that release haploid conidiospores (Figure 24.13). Sexual reproduction starts with the development of special hyphae from either one of two types of mating strains (Figure 24.13). The "male" strain produces an antheridium and the "female" strain develops an ascogonium. At fertilization, the antheridium and the ascogonium combine in plasmogamy without nuclear fusion. Special ascogenous hyphae arise, in which pairs of nuclei migrate: one from the "male" strain and one from the "female" strain. In each ascus, two or more haploid ascospores fuse their nuclei in karyogamy. During sexual reproduction, thousands of asci fill a fruiting body called the ascocarp. The diploid nucleus gives rise to haploid nuclei by meiosis. The ascospores are then released, germinate, and form hyphae that are disseminated in the environment and start new mycelia (Figure 24.14). Choices: - asexual reproduction - mitosis - cloning - sexual A:
sexual

Q: What is made up of organisms of the same species that live in the same area? Read this paragraph and choose the correct option from the provided answers: Communities consist of populations of different species. The size and growth of populations in a community are influenced by species interactions. For example, predator-prey relationships control the growth of both predator and prey populations. Choices: - countries - system - tissue - population A:
population

Q: Q: What season causes people to look forward to spring? Read this paragraph and choose the correct option from the provided answers: In the winter, many people find the snow and ice beautiful. They enjoy getting out to ski or ice-skate. Others don't find that time of year to be so much fun. When the snow melts, the roads get very sloppy and messy. Those people look forward to spring when all the ice and snow are gone and the weather is warmer. Choices: - autumn - fall - summer - winter A:
A: winter

Question: Q: What are polymers composed of many sugar building blocks called? Read this paragraph and choose the correct option from the provided answers: Choices: - monosaccarides - monomers - hydrocarbons - polysaccharides A:
Answer: polysaccharides

Q: When a male directly deposits sperm in a female during mating, this is considered what type of fertilization? Read this paragraph and choose the correct option from the provided answers: Internal Fertilization Internal fertilization occurs most often in terrestrial animals, although some aquatic animals also use this method. Internal fertilization may occur by the male directly depositing sperm in the female during mating. It may also occur by the male depositing sperm in the environment, usually in a protective structure, which a female picks up to deposit the sperm in her reproductive tract. There are three ways that offspring are produced following internal fertilization. In oviparity, fertilized eggs are laid outside the female's body and develop there, receiving nourishment from the yolk that is a part of the egg (Figure 18.7a). This occurs in some bony fish, some reptiles, a few cartilaginous fish, some amphibians, a few mammals, and all birds. Most non-avian reptiles and insects produce leathery eggs, while birds and some turtles produce eggs with high concentrations of calcium carbonate in the shell, making them hard. Chicken eggs are an example of a hard shell. The eggs of the egg-laying mammals such as the platypus and echidna are leathery. In ovoviparity, fertilized eggs are retained in the female, and the embryo obtains its nourishment from the egg's yolk. The eggs are retained in the female's body until they hatch inside of her, or she lays the eggs right before they hatch. This process helps protect the eggs until hatching. This occurs in some bony fish (like the platyfish Xiphophorus maculatus, Figure 18.7b), some sharks, lizards, some snakes (garter snake Thamnophis sirtalis), some vipers, and some invertebrate animals (Madagascar hissing cockroach Gromphadorhina portentosa). In viviparity the young are born alive. They obtain their nourishment from the female and are born in varying states of maturity. This occurs in most mammals (Figure 18.7c), some cartilaginous fish, and a few reptiles. Choices: - dual - mechanical - external - internal A:
**Answer**
internal

Q: What is the process by which almost all plants make food? Read this paragraph and choose the correct option from the provided answers: Almost all plants make food by photosynthesis. Only about 1 percent of the estimated 300,000 species of plants have lost the ability to photosynthesize. These other species are consumers, many of them predators. How do plants prey on other organisms? The Venus fly trap in Figure below shows one way this occurs. Choices: - reactions - digestion - melting - photosynthesis A:
(A).
photosynthesis
