Answer the following question given this paragraph: All plants have a characteristic life cycle that includes alternation of generations . Plants alternate between haploid and diploid generations. Alternation of generations allows for both asexual and sexual reproduction. Beginning with the diploid sporophyte , spores form from meiosis. Asexual reproduction with spores produces haploid individuals called gametophytes , which produce haploid gametes by mitosis. Sexual reproduction with gametes and fertilization produces the diploid sporophyte. A typical plant's life cycle is diagrammed in Figure below . Q: What does sexual reproduction with gametes and fertilization produce? Choices: - haploid zygote - sister chromatids - identical twins - diploid sporophyte A:
diploid sporophyte

Answer the following question given this paragraph: Smoking is the most significant cause of respiratory disease as well as cardiovascular disease and cancer. Exposure to tobacco smoke by smoking or by breathing air that contains tobacco smoke is the leading cause of preventable death in the United States. Regular smokers die about 10 years earlier than nonsmokers. The Centers for Disease Control and Prevention (CDC) describes tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of [early] death worldwide. ". Q: What is the most significant cause of respiratory disease as well as cardiovascular disease and cancer? Choices: - sleeping - running - driving - smoking A:
(Answer)
smoking
Ques: Answer the following question given this paragraph: Dissolved mineral salts wash into the ocean. As ocean water evaporates, it leaves the salts behind. This makes the water saltier. Ocean water is about 3.5 percent salts. The main salt is sodium chloride. Q: Concentration of what, the substance left behind when ocean water evaporates, is about 3.5 percent? Choices: - hydrogen - sugar - quartz - salts A:
Ans: salts

Answer the following question given this paragraph: Staying balanced when riding a scooter requires control over the body's muscles. The nervous system controls the muscles and maintains balance. Q: What helps control the muscles and maintain balance? Choices: - circulatory system - muscular system - lymphatic system - nervous system A:
(A).
nervous system
Ques:Answer the following question given this paragraph: Almost all fungi have a single common ancestor. The earliest fungi may have evolved about 600 million years ago. Fungi colonized land at least 460 million years ago. By 250 million years ago, they may have been the dominant life forms on Earth. Q: Evolving from a single common ancestor, what group of organisms was perhaps the dominant life form on earth 250 million years ago? Choices: - acids - atoms - proteins - fungi A:

Ans:fungi
Ques: Answer the following question given this paragraph: Sweat Glands When the body becomes warm, sudoriferous glands produce sweat to cool the body. Sweat glands develop from epidermal projections into the dermis and are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There are two types of sweat glands, each secreting slightly different products. An eccrine sweat gland is type of gland that produces a hypotonic sweat for thermoregulation. These glands are found all over the skin's surface, but are especially abundant on the palms of the hand, the soles of the feet, and the forehead (Figure 5.14). They are coiled glands lying deep in the dermis, with the duct rising up to a pore on the skin surface, where the sweat is released. This type of sweat, released by exocytosis, is hypotonic and composed mostly of water, with some salt, antibodies, traces of metabolic waste, and dermicidin, an antimicrobial peptide. Eccrine glands are a primary component of thermoregulation in humans and thus help to maintain homeostasis. Q: What do sudoriferous glands secrete? Choices: - water - moving - tissue - sweat A:
Ans:
sweat
