Answer the following question given this paragraph: Characteristics of Amphibians As tetrapods, most amphibians are characterized by four well-developed limbs. Some species of salamanders and all caecilians are functionally limbless; their limbs are vestigial. An important characteristic of extant amphibians is a moist, permeable skin that is achieved via mucus glands that keep the skin moist; thus, exchange of oxygen and carbon dioxide with the environment can take place through it ( cutaneous respiration). Additional characteristics of amphibians include pedicellate teethteeth in which the root and crown are calcified, separated by a zone of noncalcified tissueand a papilla amphibiorum and papilla basilaris, structures of the inner ear that are sensitive to frequencies below and above 10,00 hertz, respectively. Amphibians also have an auricular operculum, which is an extra bone in the ear that transmits sounds to the inner ear. All extant adult amphibians are carnivorous, and some terrestrial amphibians have a sticky tongue that is used to capture prey. Q: Amphibians have permeable skin which allows for the exchange of oxygen and carbon dioxide, what is this "breathing called?" Choices: - variant respiration - benign respiration - aquatic respiration - cutaneous respiration A:
cutaneous respiration

Answer the following question given this paragraph: Sugars are simple carbohydrates. Molecules of sugar have just a few carbon atoms. The simplest sugar is glucose (C 6 H 12 O 6 ). Glucose is the sugar that the cells of living things use for energy. Plants and some other organisms make glucose in the process of photosynthesis. Living things that cannot make glucose obtain it by consuming plants or these other organisms. Q: What is the sugar that the cells of living things use for energy? Choices: - insulin - sucrose - chlorophyll - glucose A:
(A).
glucose
Ques:Answer the following question given this paragraph: Are there male and female bacteria? Of course the answer is no. So, sexual reproduction does not occur in bacteria. But not all new bacteria are clones. This is because bacteria can acquire new DNA. This process occurs in three different ways:. Q: Do bacteria sexually reproduce? Choices: - sometimes - yes - they don't reproduce - no A:

Ans:no
Answer the following question given this paragraph: In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane. There are two main kinds of endocytosis: pinocytosis and phagocytosis. Q: What is the term for a particle from outside the cell engulfing the cells membrane? Choices: - metastasis - endometriosis - mitosis - endocytosis A:
endocytosis
