Answer the following question given this paragraph: Detritivores are decomposers that consume dead leaves, animal feces, and other organic debris that collects on the ground or at the bottom of a body of water. Examples of detritivores include earthworms and catfish. You can see another example in Figure below . Q: What is the term for decomposers that consume dead leaves, animal feces, and other organic debris collected on the ground or at the bottom of water? Choices: - scavengers - recyclers - consumers - detritivores A:
detritivores

Answer the following question given this paragraph: The penis is an external, cylinder-shaped organ that contains the urethra. The urethra is the tube that carries urine out of the body. It also carries sperm out of the body. Q: What does the urethra do? Choices: - filters urine and makes sperm - stores sperm and urine - makes sperm and evacuates bowels - carries urine and sperm out of the body A:
(Answer)
carries urine and sperm out of the body
Ques: Answer the following question given this paragraph: Like mitochondria, plastids contain their own DNA. Therefore, according to endosymbiotic theory, plastids may also have evolved from ancient, free-living prokaryotes that invaded larger prokaryotic cells. If so, they allowed early eukaryotes to make food and produce oxygen. Q: Like mitochondria, plastids contain their own what? Choices: - riboflavin - bacteria - molecule - dna A:
Ans: dna
(Q).
Answer the following question given this paragraph: 39.3 | Breathing By the end of this section, you will be able to: Describe how the structures of the lungs and thoracic cavity control the mechanics of breathing Explain the importance of compliance and resistance in the lungs Discuss problems that may arise due to a V/Q mismatch Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing. Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm. Q: Mammalian lungs are located in what cavity, where they are surrounded and protected by the rib cage, intercostal muscles, and chest wall? Choices: - ventral - abdominopelvic - dorsal - thoracic A:
(A).
thoracic
Ques:Answer the following question given this paragraph: Life Cycle of a Conifer Pine trees are conifers (cone bearing) and carry both male and female sporophylls on the same mature sporophyte. Therefore, they are monoecious plants. Like all gymnosperms, pines are heterosporous and generate two different types of spores: male microspores and female megaspores. In the male cones, or staminate cones, the microsporocytes give rise to pollen grains by meiosis. In the spring, large amounts of yellow pollen are released and carried by the wind. Some gametophytes will land on a female cone. Pollination is defined as the initiation of pollen tube growth. The pollen tube develops slowly, and the generative cell in the pollen grain divides into two haploid sperm cells by mitosis. At fertilization, one of the sperm cells will finally unite its haploid nucleus with the haploid nucleus of a haploid egg cell. Female cones, or ovulate cones, contain two ovules per scale. One megaspore mother cell, or megasporocyte, undergoes meiosis in each ovule. Three of the four cells break down; only a single surviving cell will develop into a female multicellular gametophyte, which encloses archegonia (an archegonium is a reproductive organ that contains a single large egg). Upon fertilization, the diploid egg will give rise to the embryo, which is enclosed in a seed coat of tissue from the parent plant. Fertilization and seed development is a long process in pine trees: it may take up to two years after pollination. The seed that is formed contains three generations of tissues: the seed coat that originates from the sporophyte tissue, the gametophyte that will provide nutrients, and the embryo itself. Q: Because conifers carry both male and female sporophylls on the same mature sporophyte, they are considered what type of plant? Choices: - siliceous - bioecious - dioecious - monoecious A:

Ans:monoecious
Ques: Answer the following question given this paragraph: Steps in Glycolysis The 10 reactions of glycolysis, summarized in Figure 20.16 "Glycolysis", can be divided into two phases. In the first 5 reactionsphase Iglucose is broken down into two molecules of glyceraldehyde 3-phosphate. In the last five reactionsphase IIeach glyceraldehyde 3-phosphate is converted into pyruvate, and ATP is generated. Notice that all the intermediates in glycolysis are phosphorylated and contain either six or three carbon atoms. Figure 20.16 Glycolysis. Q: What does glycolysis generate in phase ii? Choices: - amino acids - dna - adp - atp A:
Ans:
atp
