Answer the following question given this paragraph: Which of the following statements about the anatomy of a mollusk is false? a. Mollusks have a radula for grinding food. A digestive gland is connected to the stomach. The tissue beneath the shell is called the mantle. The digestive system includes a gizzard, a stomach, a digestive gland, and the intestine. Mollusks have a muscular foot, which is used for locomotion and anchorage, and varies in shape and function, depending on the type of mollusk under study. In shelled mollusks, this foot is usually the same size as the opening of the shell. The foot is a retractable as well as an extendable organ. The foot is the ventral-most organ, whereas the mantle is the limiting dorsal organ. Mollusks are eucoelomate, but the coelomic cavity is restricted to a cavity around the heart in adult animals. The mantle cavity develops independently of the coelomic cavity. The visceral mass is present above the foot, in the visceral hump. This includes digestive, nervous, excretory, reproductive, and respiratory systems. Mollusk species that are exclusively aquatic have gills for respiration, whereas some terrestrial species have lungs for respiration. Additionally, a tongue-like organ called a radula, which bears chitinous tooth-like. Q: What do aquatic mollusk species use for respiration? Choices: - lungs - phototropism - pores - gills A:
gills

Answer the following question given this paragraph: Seeds and Pollen as an Evolutionary Adaptation to Dry Land Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into a sporophyte. Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage. Several layers of hardened tissue prevent desiccation, and free reproduction from the need for a constant supply of water. Furthermore, seeds remain in a state of dormancyinduced by desiccation and the hormone abscisic aciduntil conditions for growth become favorable. Whether blown by the. Q: Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into what? Choices: - sperm - gametophyte - ovary - sporophyte A:
(Answer)
sporophyte
Ques: Answer the following question given this paragraph: 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. Q: What is the process by which almost all plants make food? Choices: - reactions - digestion - melting - photosynthesis A:
Ans: photosynthesis

Answer the following question given this paragraph: If the first three are true but not the fourth, then that object is a dwarf planet . We now call Pluto a dwarf planet. There are other dwarf planets in the solar system. They are Eris, Ceres, Makemake and Haumea. There are many other reasons why Pluto does not fit with the other planets in our solar system. Q: What is pluto now called? Choices: - asteroid - planet - meteor - dwarf planet A:
(A).
dwarf planet
Ques:Answer the following question given this paragraph: The four planets closest to the SunMercury, Venus, Earth, and Marsare the inner planets or terrestrial planets ( Figure below ). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets. Q: Where are the terrestrial planets located, in relation to the sun? Choices: - farthest - To the left - To the right - closest A:

Ans:closest
Ques:Answer the following question given this paragraph: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas. The particles can pull apart and spread out. This explains why gases have neither a fixed volume nor a fixed shape. Q: If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a what? Choices: - liquid - solid - vapor - gas A:

Ans:
gas
