Answer the following question given this paragraph: All animals have innate behaviors, even human beings. Can you think of human behaviors that do not have to be learned? Chances are, you will have a hard time thinking of any. The only truly innate behaviors in humans are called reflex behaviors . They occur mainly in babies. Like innate behaviors in other animals, reflex behaviors in human babies may help them survive. Q: What are the only truly innate behaviors in humans called? Choices: - automatic movements - flinches - feats - reflexes A:
reflexes
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
Q: Answer the following question given this paragraph: Ground tissue makes up most of the interior of a plant. It carries out basic metabolic functions and stores food and water. Q: What makes up most of the interior of a plant? Choices: - conjunction tissue - support tissue - transport tissue - ground tissue A:
A: ground tissue
Question: Answer the following question given this paragraph: All reptiles are heterotrophs, and the majority eats other animals. Heterotrophs that eat only or mainly animals are called carnivores. Large carnivorous reptiles such as crocodilians are the top predators in their ecosystems. They prey on large birds, fish, deer, turtles, and sometimes farm livestock. Their powerful jaws are strong enough to crush bones and turtle shells. Smaller carnivorous reptilesincluding tuataras, snakes, and many lizardsare lower-level predators. They prey on small animals such as insects, frogs, birds, and mice. Q: What is the term for heterotrophs that eat only or mainly animals? Choices: - parasites - predators - omnivores - carnivores A:
Answer: carnivores

Answer the following question given this paragraph: In classical physics, momentum is a simple product of mass and velocity. However, we saw in the last section that when special relativity is taken into account, massive objects have a speed limit. What effect do you think mass and velocity have on the momentum of objects moving at relativistic speeds? Momentum is one of the most important concepts in physics. The broadest form of Newton's second law is stated in terms of momentum. Momentum is conserved whenever the net external force on a system is zero. This makes momentum conservation a fundamental tool for analyzing collisions. All of Work, Energy, and Energy Resources is devoted to momentum, and momentum has been important for many other topics as well, particularly where collisions were involved. We will see that momentum has the same importance in modern physics. Relativistic momentum is conserved, and much of what we know about subatomic structure comes from the analysis of collisions of accelerator-produced relativistic particles. The first postulate of relativity states that the laws of physics are the same in all inertial frames. Does the law of conservation of momentum survive this requirement at high velocities? The answer is yes, provided that the momentum is defined as follows. Relativistic Momentum Relativistic momentum. Q: In classical physics, momentum is a simple product of mass and this? Choices: - acceleration - speed - direction - velocity A:
**Answer**
velocity
Q: Answer the following question given this paragraph: The thyroid gland is a large gland in the neck. Thyroid hormones increase the rate of metabolism in cells throughout the body. They control how quickly cells use energy and make proteins. Q: Hormones produced by what gland in the neck increase the rate of metabolism in cells throughout the body? Choices: - pituitary - kidney - thymus - thyroid A:
A: thyroid
