Answer the following question given this paragraph: The stability of an ecosystem depends on the actions of the decomposers. Examples of decomposers include mushrooms on a decaying log. Bacteria in the soil are also decomposers. Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients. The carbon and nitrogen necessary to build organic compounds, and then cells, allowing an organism to grow, would be insufficient. Other nutrients necessary for an organism to function properly would also not be sufficient. Essentially, many organisms could not exist. Q: The stability of an ecosystem depends on the actions of what, exemplified by mushrooms on a decaying log and bacteria in soil? Choices: - whitefly - fluxes - aphids - decomposers A:
decomposers

Answer the following question given this paragraph: An ovule is a female reproductive structure in seed plants that contains a tiny female gametophyte. The gametophyte produces an egg cell. After the egg is fertilized by sperm, the ovule develops into a seed. Q: In seed plants, after fertilization, what will the ovule eventually develop into? Choices: - cone - root - flower - seed A:
(Answer)
seed
Ques: Answer the following question given this paragraph: 16.6 Nervous System The nervous system is made up of neurons and glia. Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues. Glia are non-neuronal cells in the nervous system that support neuronal development and signaling. There are several types of glia that serve different functions. Neurons have a resting potential across their membranes and when they are stimulated by a strong enough signal from another neuron an action potential may carry an electrochemical signal along the neuron to a synapse with another neuron. Neurotransmitters carry signals across synapses to initiate a response in another neuron. The vertebrate central nervous system contains the brain and the spinal cord, which are covered and protected by three meninges. The brain contains structurally and functionally defined regions. In mammals, these include the cortex (which can be broken down into four primary functional lobes: frontal, temporal, occipital, and parietal), basal ganglia, thalamus, hypothalamus, limbic system, cerebellum, and brainstemalthough structures in some of these designations overlap. While functions may be primarily localized to one structure in the brain, most complex functions, like language and sleep, involve neurons in multiple brain regions. The spinal cord is the information superhighway that connects the brain with the rest of the body through its connections with peripheral nerves. It transmits sensory and motor input and also controls motor reflexes. The peripheral nervous system contains both the autonomic and sensory-somatic nervous systems. The autonomic nervous system provides unconscious control over visceral functions and has two divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is activated in stressful situations to prepare the animal for a "fight-orflight" response. The parasympathetic nervous... Q: What are specialized cells that are capable of sending electrical as well as chemical signals? Choices: - hormones - ions - enzymes - neurons A:
Ans: neurons

Answer the following question given this paragraph: When heat flows into an object, its thermal energy increases and so does its temperature. Q: When heat flows into an object, its thermal energy increases and so does its what? Choices: - matter - speed - color - temperature A:
(A).
temperature
Ques:Answer the following question given this paragraph: Did you ever wonder how a microwave works? It directs invisible waves of radiation toward the food placed inside of it. The radiation transfers energy to the food, causing it to get warmer. The radiation is in the form of microwaves, which are a type of electromagnetic waves. Q: What type of invisible waves are used in microwaves? Choices: - convection - electric - thermal - radiation A:

Ans:radiation
Ques:Answer the following question given this paragraph: Condensation reactions are the chemical processes by which large organic compounds are synthesized from their monomeric units. Hydrolysis reactions are the reverse process. During condensation reactions, water is produced from the two molecules being bonded together; an H from one monomer is joined to an -OH from another molecule, producing H 2 O. Q: What is produced during a condensation reaction? Choices: - rain - wind - fire - water A:

Ans:
water
