Answer the following question given this paragraph: Biotechnology is technology based on biological applications. These applications are increasingly used in medicine, agriculture and food science. Biotechnology combines many features of biology, including genetics, molecular biology, biochemistry, embryology, and cell biology. Many aspects of biotechnology center around DNA and its applications, otherwise known as DNA technology. We could devote a whole textbook to current applications of biotechnology, however, we will focus on the applications towards medicine and agriculture, and the extension into the forensic sciences. First, though, we need to understand DNA technology. Q: Biotechnology uses what to solve problems? Choices: - psycology - ecology - geology - biology A:
biology

Answer the following question given this paragraph: As the organism grows more sophisticated, gene regulation becomes more complex, though prokaryotic organisms possess some highly regulated systems. Some human genes are controlled by many activators and repressors working together. Obviously, a mutation in a cis-regulatory region, such as the promoter, can greatly affect the proper expression of a gene. It may keep the gene permanently off, such that no protein can be made, or it can keep the gene permanently on, such that the corresponding protein is constantly made. Both of these can have detremental effects on the cell. Q: As the organism grows more sophisticated, what happens to the process of gene regulation? Choices: - degenerates - becomes fractured - becomes simplified - becomes more complex A:
(Answer)
becomes more complex
Ques: Answer the following question given this paragraph: Earth goes through regular changes in its position relative to the Sun. Its orbit changes slightly. Earth also wobbles on its axis of rotation. The planet also changes its axial tilt , the angle of its axis of rotation. These changes can affect Earth's temperature. Q: What do you call the angle of the earth's axis of rotation? Choices: - dynamic tilt - vertical tilt - horizontal tilt - axial tilt A:
Ans: axial tilt

Answer the following question given this paragraph: Bacterial contamination of foods can lead to digestive problems, an illness known as food poisoning . Raw eggs and undercooked meats commonly carry the bacteria that can cause food poisoning. Food poisoning can be prevented by cooking meat thoroughly and washing surfaces that have been in contact with raw meat. Washing your hands before and after handling food also helps prevent contamination. Q: Bacterial contamination of foods can lead to digestive problems called what? Choices: - cancer - the flu - butterflies in your stomach - food poisoning A:
(A).
food poisoning
Ques:Answer the following question given this paragraph: Diencephalon The diencephalon is beneath the cerebrum and includes the thalamus and hypothalamus. In the somatic nervous system, the thalamus is an important relay for communication between the cerebrum and the rest of the nervous system. The hypothalamus has both somatic and autonomic functions. In addition, the hypothalamus communicates with the limbic system, which controls emotions and memory functions. Sensory input to the thalamus comes from most of the special senses and ascending somatosensory tracts. Each sensory system is relayed through a particular nucleus in the thalamus. The thalamus is a required transfer point for most sensory tracts that reach the cerebral cortex, where conscious sensory perception begins. The one exception to this rule is the olfactory system. The olfactory tract axons from the olfactory bulb project directly to the cerebral cortex, along with the limbic system and hypothalamus. The thalamus is a collection of several nuclei that can be categorized into three anatomical groups. White matter running through the thalamus defines the three major regions of the thalamus, which are an anterior nucleus, a medial nucleus, and a lateral group of nuclei. The anterior nucleus serves as a relay between the hypothalamus and the emotion and memoryproducing limbic system. The medial nuclei serve as a relay for information from the limbic system and basal ganglia to the cerebral cortex. This allows memory creation during learning, but also determines alertness. The special and somatic senses connect to the lateral nuclei, where their information is relayed to the appropriate sensory cortex of the cerebrum. Q: What is beneath the cerebrum and includes the thalamus and hypothalamus? Choices: - rendalen - brain stem - subvocalization - diencephalon A:

Ans:diencephalon
