Divide plants into two groups of twenty-five. Plant twenty-five seeds in pots with potting soil without compost; this is the control group. Plant the other twenty-five in pots with potting soil and a specific amount of compost added; this is the experimental group. Place the pots under grow lights. After germination, measure the height of the plants at set intervals (e.g., every two days) for a set amount of time (e.g., two weeks). The IV is the presence or absence of compost. The DV is the height of plants. Twenty-five plants per group is a good sample size; all obvious variables are controlled. The experiment is simple and specifically described, so it can be replicated. The seeds were assigned randomly; there is no obvious bias in the experiment.

The digestive and circulatory compartment of cnidarians is called the gastrovascular cavity. So, the correct option is (A).
What are Cnidarians?The word Cnidaria derive from the Greek word "cnidos," which means stinging nettle.
Cnidaria is the phylum which comes under Kingdom Animalia. This phylum contains over 11,000 species of aquatic animals found in both freshwater and marine environments. Their specialty is cnidocytes which are specialized cells which they use mainly to capture prey.
The gastrovascular cavity is defined as the major site for digestion of food and absorption of nutrients in cnidarians in which food passes through the mouth and enters the cavity. Inside the gastrovascular cavity, there is a cell membrane that wraps around food particles and then moves them into the internal cavity.
Thus, the digestive and circulatory compartment of cnidarians is called the gastrovascular cavity. So, the correct option is (A).

Pseudopods is a tool for movement in many protists such as amoeba. Pseudopods is the extension of cytoplasm which enables the organism to move from place to place and capture the food by engulf small particles. This protists has chloroplast because chloroplast is responsible for the production of food materials from sunlight in the process of photosynthesis.
What would happen if you did not have the stapedius and tensor tympani muscles? A. The ear canal would stay permanently closed. B. The ear canal would stay permanently open. C. The vestibular canals would be permanently misaligned, resulting in hearing and equilibrium problems. D. Loud sounds would cause the ossicles to move too much, potentially causing damage to the inner ear. E. The cochlea would not be secured in place and might move around.
Explanation:
Both the stapedius and tensor tympani are striated musclesThe stapedius is about 6 mm in length, arises from the pyramidal process and the tendon attaches to the posterior neck of the stapesThe stapedius is a muscle with a high oxidative capacityThe tensor tympani is about 25 mm in length, the muscle is not as strong as the stapedius, and the tendon also contains more elastic tissue and fatThe tensor tympani courses through a bony canal in the wall of the anterior middle ear, and attaches to the neck of the manubriumThe tensor tympani and stapedius muscles are protective reflexesThey reduce the amount of sound that gets into the inner earThey are somewhat similar to the blink reflex thus they can be triggered by loud noise, and when they go off, both ears can be involvedIf stapedius and tensor tympani muscles is not present then loud sounds would cause the ossicles to move too much, potentially causing damage to the inner earIn the absence of the stapedius and the tensor tympani muscles the loud sounds would make the ossicles to move too much, thus, causing damage to the inner ear.
• The stapedius and the tensor tympani are the protective reflexes.
• They are found in the middle ear and are associated with the ear ossicles.
• They minimize the amount of sound that gets into the inner ear, they are identical to the blink reflex.
• Both these muscles contract in response to incoming intense or loud sounds, which strike the eardrum, and thus minimizing the transmission of sound within the inner ear.
• Of the two muscles, the stapedius is considered to be more sensitive to sound in comparison to the tensor tympani.
Thus, the correct answer is option D.

Final answer:
A theory in science is a well-supported comprehensive explanation of natural phenomena, akin to a fact, and is vital for making predictions about the natural world. It is much more than a guess, distinguishing it from the everyday use of the term 'theory'.
Explanation:
In the context of science, the term theory refers to a comprehensive explanation of an important feature of nature that is supported by a substantial body of evidence. It's important to distinguish this scientific use of the term from the way 'theory' is used colloquially, where it might just mean a guess or speculation. Scientifically, a theory is akin to a fact and represents our most reliable understanding of natural phenomena. Examples of scientific theories include the theory of evolution, cell theory, and germ theory.
The United States National Academy of Sciences defines a theory as a well-established scientific explanation that is unlikely to be altered by new evidence. This conceptual framework allows scientists to make predictions about phenomena that have not yet been observed, placing theories at the bedrock of scientific understanding of the natural world.
Signal to which an organism responds
A stimulus is a signal to which an organism responds. Stimuli can be internal like hunger or thirst, or external like change in temperature or light. An organism's evolutionary adaptations often determine its responses to these signals.
Explanation:A signal to which an organism responds is known as a stimulus. Stimuli can be external or internal. External stimuli include changes in the environment like temperature, light, or sound. Internal stimuli come from within the organism itself, such as hunger or thirst. An organism's response to a stimulus is often a result of adaptations developed over time. This reactionary process is a critical aspect of an organism's survival and continued existence.

Organisms respond to signals or stimuli surrounding them in their environment. These reactions can be a movement towards or away from the stimuli or diverse forms of communication within species. Even single-celled organisms like bacteria can process and respond to environmental signals.
Explanation:The signal to which an organism responds can vary widely, but generally, it refers to environmental cues or stimuli which trigger a reaction or response in the organism. Sensitivity or response to stimuli is an inherent characteristic of living organisms, emphasizing their ability to interact with their surroundings. This response can include movements towards or away from the source of stimuli (positive or negative response).
For instance, a plant might respond positively to a light source by bending towards it, a reaction known as phototaxis. Likewise, bacteria can move towards or away from chemical sources (chemotaxis) or light (phototaxis).
Communication within species also involves the use of signals as stimuli. Particularly, animals engage in communication using signals that could be visual, aural(sound), chemical (like pheromones), or tactile(touch). In some species such as the three-spined stickleback, a red region in the lower half signals males to become aggressive and females to mate. These stimuli-based responses can be instinctual, learned, or a mix of both.
Single-celled organisms, like bacteria, are also capable of signal processing. They respond to environmental signals like nutrient levels by using intracellular signaling, and sometimes, they release molecules as signals to communicate with each other.

Once the body has begun shivering, what happens to make it stop shivering?
A)When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shivering.
B)When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shivering.
C)When body temperature is below normal, the nervous system sends a message to the skeletal system to stop shivering.
D)When body temperature is below normal, the respiratory system sends a message to the muscular system to stop shivering.
Answer:
B
Explanation:
Brain/nervous system in charge of everything
Shivering stops when the hypothalamus in the brain signals that body temperature has returned to normal, prompting the nervous system to halt the muscle contractions.
Explanation:When the body begins to shiver due to cold, this is part of a process called thermoregulation, coordinated by the nervous system to maintain homeostasis. The hypothalamus in the brain detects that the body temperature is below its set point and initiates shivering to generate heat. Shivering involves rapid contractions of the skeletal muscles, which help to increase body temperature. Once the temperature returns to the normal range, the hypothalamus sends signals, via the nervous system, to stop the shivering response.
Therefore, the correct answer to the question is B) When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shivering.
