Ques:Answer the following question given this paragraph: 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). Q: Asci are used by mycelia for what kind of reproduction? Choices: - asexual reproduction - mitosis - cloning - sexual A:

Ans:sexual

Ques:Answer the following question given this paragraph: A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. The more general term for rusting and other similar processes is corrosion. Other terms that are commonly used in descriptions of chemical changes are burn, rot, explode, decompose, and ferment. Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. Q: A chemical property describes the ability of a substance to undergo a specific what? Choices: - weight Change - radiation change - liquid change - chemical change A:

Ans:chemical change

Ques:Answer the following question given this paragraph: The radiative zone is the next layer out. It has a temperature of about 4 million degrees C. Energy from the core travels through the radiative zone. The rate the energy travels is extremely slow. Light particles, called photons, can only travel a few millimeters before they hit another particle. The particles are absorbed and then released again. It may take 50 million years for a photon to travel all the way through the radiative zone. Q: What do you call the light particles that travel through the radiative zone? Choices: - neutrons - ions - electrons - photons A:

Ans:photons

Ques:Answer the following question given this paragraph: Primates have slower rates of development than other mammals their size. They reach maturity later and have longer lifespans. Being dependent on adults for a long maturation period gives young primates plenty of time to learn from their elders. Q: Being dependent on adults for a long maturation period allows young primates ample time for what? Choices: - sleeping - attachment - socialization - learning A:

Ans:
learning
