Q: Many cancers, as well as autism, are thought to have what component, which is certainly a factor in asthma? Read this paragraph and choose the correct option from the provided answers: Does everyone who smokes develop lung cancer? No, of course not. Is it possible to get lung cancer without smoking? Sadly, yes it is. That's not to say there is no relationship between the two: smoking is still the leading cause of lung cancer. But it does suggest that a person's genetic background has a role in this process. Apart form true single gene disorders, environmental factors, or environmental triggers , may determine the development of disease in individuals genetically predisposed to a particular condition. Environmental triggers may include stress, physical and mental abuse, diet, exposure to toxins, pathogens, and radiation. Many cancers are thought to have an environmental component. It has been suggested that environmental factors play a role in autism as well. Asthma is obviously triggered under certain environmental conditions. Choices: - emotional - critical - ecological - environmental A:
environmental

Q: Cellular respiration is the reverse or opposite of what? Read this paragraph and choose the correct option from the provided answers: Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP ( Figure below ). ATP , or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street. But cellular respiration is slightly more complicated than just converting the energy from glucose into ATP. Cellular respiration can be described as the reverse or opposite of photosynthesis. During cellular respiration, glucose, in the presence of oxygen, is converted into carbon dioxide and water. Recall that carbon dioxide and water are the starting products of photosynthesis. What are the products of photosynthesis?. Choices: - spermatogenesis - reproduction - glycolysis - photosynthesis A:
(Answer)
photosynthesis

Ques: Q: Vertebrates have tissues which are organized into organs which in turn are organized into what? Read this paragraph and choose the correct option from the provided answers: 24.4 Subphylum Vertebrata (Vertebra from Latin vertere, to turn). Characterized by separate bones or cartilage blocks firmly joined as a backbone. The backbone supports and protects a dorsal nerve cord. Vertebrates have tissues which are organized into organs which in turn are organized into organ systems. All vertebrates share the following characteristics: - segmentation - a true coelom - bilateral symmetry - cephalization - a backbone - a bony skull - a closed circulatory system - chambered heart - two pairs of jointed appendages - tissues organized into organs Vertebrate Organ Systems: - Nervous System - Circulatory System - Digestive System Respiratory System - Reproductive System - Excretory System Vertebral column: Not present in higher vertebrate adults. (In humans, the gel-like, spongy core of the vertebral column is the only remainder. Ruptured or herniated disc is an injury to this. ) Cranium: Composite structure of bone/cartilage. Two functions: 1. Supports sensory organs of head and 2. Encloses or partially encloses the brain. What evolutionary relationship could we imagine between sessile echinoderms and the higher chordate animals? Paedomorphic (child-form) hypothesis: basically, evolution of sexual reproduction in what had previously been a larval life stage, or the retention of at least one juvenile characteristic into the adult (adult = sexually reproducing) stage. Some scientists believe that this occurred in a proto-chordate animal lineage. Maybe chordates (and vertebrates) arose from sessile (attached) ancestors. Selection in these proto-chordates maybe began to favor more time in the larval stage, as feeding was more successful or mortality lower in this stage. As larvae got bigger physics shows that the cilia become less efficient for locomotion, favoring the undulating motion allowed by a notochord. Is this hypothesis crazy? A similar example of this today is Epemeroptera, the mayfly, which has almost abandoned its adult stage. Its one-year lifespan is mostly larval with just a... Choices: - artificial systems - information systems - maturation systems - organ systems A:
Ans: organ systems

Q: What is the term for when organisms need other organisms to survive? Read this paragraph and choose the correct option from the provided answers: All living things depend on their environment to supply them with what they need, including food, water, and shelter. Their environment consists of physical factorssuch as soil, air, and temperatureand also of other organisms. An organism is an individual living thing. Many living things interact with other organisms in their environment. In fact, they may need other organisms in order to survive. This is known as interdependence . For example, living things that cannot make their own food must eat other organisms for food. Other interactions between living things include symbiosis and competition. Choices: - intradependence - realization - coexistence - interdependence A:
(A).
interdependence

Ques:Q: Visible light is one type of this radiation? Read this paragraph and choose the correct option from the provided answers: Visible light is one type of electromagnetic radiation , which is a form of energy that exhibits wavelike behavior as it moves through space. Other types of electromagnetic radiation include gamma rays, x-rays, ultraviolet light, infrared light, microwaves, and radio waves. The figure below shows the electromagnetic spectrum , which is all forms of electromagnetic radiation. Notice that visible light makes up only a very, very small portion of the entire electromagnetic spectrum. All electromagnetic radiation moves through a vacuum at a constant speed of 2.998 10 8 m/s. While the presence of air molecules slows the speed of light by a very small amount, we will use the value of 3.00 10 8 m/s as the speed of light in air. Choices: - neutron - Ionizing - Gamma - electromagnetic A:

Ans:electromagnetic

Question: Q: When does coal release most of its energy? Read this paragraph and choose the correct option from the provided answers: To prepare coal for use, the coal is first crushed into powder and burned in a furnace. Like other fuels, coal releases most of its energy as heat when it burns. The heat from the burning coal is used to boil water. This makes steam. The steam spins turbines, which creates electricity. Choices: - when forming - when compressed - when falling - when burning A:
Answer:
when burning
