Hypothesis: If the fish which eats food exposed to microwaves, then the fish will become smarter and be able to swim faster.
Control group: the fish, the maze
independent group: the type of food which is being given
Dependent group: the time the fish is able to swim through the maze
Conclusion: Although the results did show that both fishes had some difference between their before and after, you can see a greater difference of time in the group of fishes which had ate the special food.

Monomers and polymers how do they affect the molecules that organisms are made of?
Answer:
The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.” ... In the process, a water molecule is formed.

A. interneurons
B. sensory neurons
C. peripheral nervous system
D. central nervous system
Will mark brainlest for quick and correct answer
Answer:
The CNS
Explanation:
First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
The nervous system has been the most crucial organ system that acts as the command center. The CNS of the nervous system is very well protected by the bones. Thus, option D is correct.
What is CNS?CNS has been abbreviated for the central nervous system which comprises the spinal cord and the brain. The spinal cord is located at the dorsal surface and the brain is at the anterior location of the body.
The CNS has been enclosed by the skeletal system as the spinal cord is confined inside the vertebral column and the brain inside the skull. They have cerebrospinal fluid that acts as the cushion that protects these structures from shock and injuries.
Therefore, option D. CNS has been the part of the nervous system that is protected by the skeletal system (bones).

Explain- the 8 characteristics that are required for life
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.
Explanation:
Sensitivity or Response to Stimuli
Organisms can respond to diverse stimuli. For example, plants can grow toward a source of light, climb on fences and walls, or respond to touch. Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light (phototaxis). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is considered a negative response.
Reproduction
Single-celled organisms reproduce by first duplicating their DNA. They then divide it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germline cells that will form new individuals. When reproduction occurs, genes containing DNA are passed along to an organism’s offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, such as size and shape.
Growth and Development
All organisms grow and develop following specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young will grow up to exhibit many of the same characteristics as its parents.
Regulation
Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses. Two examples of internal functions regulated in an organism are nutrient transport and blood flow. Organs (groups of tissues working together) perform specific functions, such as carrying oxygen throughout the body, removing wastes, delivering nutrients to every cell, and cooling the body.
Homeostasis
In order to function properly, cells need to have appropriate conditions such as proper temperature, pH, and appropriate concentration of diverse chemicals. These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through homeostasis (literally, “steady state”)—the ability of an organism to maintain constant internal conditions. For example, an organism needs to regulate body temperature through a process known as thermoregulation. Organisms that live in cold climates, such as the polar bear, have body structures that help them withstand low temperatures and conserve body heat. Structures that aid in this type of insulation include fur, feathers, blubber, and fat. In hot climates, organisms have methods (such as perspiration in humans or panting in dogs) that help them to shed excess body heat.
Energy Processing
All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food; others use chemical energy in molecules they take in as food.
Evolution
As a population of organisms interacts with the environment, individuals with traits that contribute to reproduction and survival in that particular environment will leave more offspring. Over time those advantageous traits (called adaptations ) will become more common in the population. This process, change over time, is called evolution, and it is one of the processes that explain the diverse species seen in biology. Adaptations help organisms survive in their ecological niches, and adaptive traits may be structural, behavioral, or physiological; as such, adaptations frequently involve other properties of organisms such as homeostasis, reproduction, and growth and development.
Explain in your own words an atom and an element.
Answer:
Explain in your own words an atom and an element.
Explanation:
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
Which molecule separates the contents inside of the cell from the contents outside of the cell
Answer:
Which molecule separates the contents inside of the cell from the contents outside of the cell
Explanation:
cell membrane
Every cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.
The molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.
Lipids represent a broad range of biomolecules made up of carbon (C), hydrogen (H) and oxygen (O) atoms.In some cases, lipids also contain phosphorus (P), nitrogen (N) or sulfur (S).Lipids (i.e., phospholipids and cholesterol) represent the main biomolecules of the cell membrane whose function is to separate the interior of the cell from its surrounding environment.In conclusion, the molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.

What is Fermentation?Fermentation is defined as a metabolic process that produces chemical changes in organic substrates through the action of enzymes which is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Microorganisms such as bacteria and fungi have metabolic genes that allow them to produce enzymes to break down a variety of sugar metabolites.
Yeast and sugar produce carbonic gas through fermentation which is why as the yeast consumes the sugar, it produces alcohol (ethanol) and carbonic gas (carbon dioxide) as waste products, hence the carbon dioxide trapped in the dough lifts up,
Thus, the trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.
