Q: What group of single-celled organisms lacking a nucleus comprises the most numerous organisms on earth? Read this paragraph and choose the correct option from the provided answers: No doubt you've had a sore throat before, and you've probably eaten cheese or yogurt. If so, then you've encountered the fascinating world of prokaryotes. Prokaryotes are single-celled organisms that lack a nucleus. They also lack other membrane-bound organelles. Prokaryotes are tiny and sometimes bothersome, but they are the most numerous organisms on Earth. Without them, the world would be a very different place. Prokaryotes are the simplest organisms. The first cells and organisms to evolve would be classified as prokaryotic. Choices: - eukaryotes - carbohydrates - fungi - prokaryotes A:
prokaryotes

Q: Different shapes often correlate with different what in cells? Read this paragraph and choose the correct option from the provided answers: Cells with different functions often have different shapes. The cells pictured in Figure below are just a few examples of the many different shapes that cells may have. Each type of cell in the figure has a shape that helps it do its job. For example, the job of the nerve cell is to carry messages to other cells. The nerve cell has many long extensions that reach out in all directions, allowing it to pass messages to many other cells at once. Do you see the tail-like projections on the algae cells? Algae live in water, and their tails help them swim. Pollen grains have spikes that help them stick to insects such as bees. How do you think the spikes help the pollen grains do their job? ( Hint: Insects pollinate flowers. ). Choices: - systems - enzymes - types - functions A:
functions

Q: Q: Why does water have a high surface tension? Read this paragraph and choose the correct option from the provided answers: Choices: - high freezing point - helium bonding - oxygenation - hydrogen bonding A:
A: hydrogen bonding

Question: Q: What system serves as the relay between the cns and the internal organs? Read this paragraph and choose the correct option from the provided answers: The autonomic nervous system serves as the relay between the CNS and the internal organs. It controls the lungs, the heart, smooth muscle, and exocrine and endocrine glands. The autonomic nervous system controls these organs largely without conscious control; it can continuously monitor the conditions of these different systems and implement changes as needed. Signaling to the target tissue usually involves two synapses: a preganglionic neuron (originating in the CNS) synapses to a neuron in a ganglion that, in turn, synapses on the target organ, as illustrated in Figure 35.26. There are two divisions of the autonomic nervous system that often have opposing effects: the sympathetic nervous system and the parasympathetic nervous system. Sympathetic Nervous System The sympathetic nervous system is responsible for the "fight or flight" response that occurs when an animal encounters a dangerous situation. One way to remember this is to think of the surprise a person feels when encountering a snake ("snake" and "sympathetic" both begin with "s"). Examples of functions controlled by the sympathetic nervous system include an accelerated heart rate and inhibited digestion. These functions help prepare an organism's body for the physical strain required to escape a potentially dangerous situation or to fend off a predator. Choices: - cellular nervous system - central nervous system - limbic nervous system - autonomic nervous system A:
Answer: autonomic nervous system
