Answer the following question given this paragraph: 29.6 Mammals Mammals in general are vertebrates that possess hair and mammary glands. The mammalian integument includes various secretory glands, including sebaceous glands, eccrine glands, apocrine glands, and mammary glands. Mammals are synapsids, meaning that they have a single opening in the skull. A key characteristic of synapsids is endothermy rather than the ectothermy seen in other vertebrates. Mammals probably evolved from therapsids in the late Triassic period, as the earliest known mammal fossils are from the early Jurassic period. There are three groups of mammals living today: monotremes, marsupials, and eutherians. Monotremes are unique among mammals as they lay eggs, rather than giving birth to young. Eutherian mammals are sometimes called placental mammals, because all species possess a complex placenta that connects a fetus to the mother, allowing for gas, fluid, and nutrient exchange. Q: What makes monotremes different than other mammals? Choices: - they lack backbones - they spawn - they reproduce asexually - they lay eggs A:
they lay eggs
Answer the following question given this paragraph: Q: While enzymatic hydrolysis proceeds, peristalsis moves the mixture of chyme and digestive juices along what? Choices: - esophagus - stomach - large intestine - small intestine A:
small intestine
Q: Answer the following question given this paragraph: The amount of inertia an object has is simply related to the mass of the object. Mass and Weight are two different things. Mass (typically in units of kg or grams) is basically a measure of what comprises an object. Weight is the measure of how much the force of gravity is pulling on you. In fact, instead of saying 'I weigh 80 lb. ', one could say that 'the force of gravity is pulling on me with a force of 80 lb. ' The metric unit for weight (and force) is the Newton. Q: What measures exactly how much gravity is pulling on something? Choices: - size - matter - dimension - weight A:
A: weight
Question: Answer the following question given this paragraph: Q: What do you call a substance that cannot be broken down to other substances by chemical reactions.? Choices: - a participate - a molecule - a compound - an element A:

Answer the following question given this paragraph: Nucleic acids are one of four classes of biochemical compounds. (The other three classes are carbohydrates, proteins, and lipids. ) Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus. Q: Rna and dna are types of what biochemical compounds containing the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus? Choices: - hormones - nitrous acids - amino acids - nucleic acids A:
(A).
nucleic acids
