Answer: A theory is a group of hypotheses that prove a law is true. A law is a statement of fact, but a theory is an explanation. A law is a statement of fact, but a theory is an explanation.
Explanation:
Hypotheses, theories, and laws all have natural world tests in common. Each of them are trying to provide the steps to guarantee a valid experimentation. Hypothesis: An educated guess on the natural world possibilities
Theory: An explanation of the natural world aspect
Law: An aspect of how the natural world reacts under a specific circumstance
Hypotheses, theories, and laws all have natural world tests in common. Each of them are trying to provide the steps to guarantee a valid experimentation. You cannot have a valid experimentation without each of these. However, fact is also a need.
Hope it helps
Answer:
The water plant
Explanation:
According to this question, Mason performs an experiment where he places a water plant in a test tube of water and turns it upside down in a rack by a sunny window. However, the next day, he observed that there were bubbles in the water as well as in the top of the tube.
These bubbles were actually OXYGEN GAS produced as a result of a metabolic process carried out by the water plant called PHOTOSYNTHESIS. In photosynthesis, which is the process whereby plants synthesize their food in the presence of sunlight, OXYGEN gas is given off as a waste product. The oxygen gas is what was observed by Mason as bubbles. Hence, the bubbles were produced by the WATER PLANT.
Answer: Autonomic: Acting or occurring involuntarily, without conscious control. Central nervous system: The part of the peripheral nervous system that transmits signals from the central nervous system to skeletal muscles, and from receptors of external stimuli, thereby mediating sight, hearing, and touch.

Answer:
D. an entire chromosome is added to a chromosome set
Explanation:
The rest of these are mutations in the DNA sequence
Answer:
The distance between A and B is less than the distance between B and C.
Explanation:
Crossing over is the exchange of genetic segments that occurs between the chromatids of homologous chromosomes during prophase I of meiosis I. The process of crossing over requires the genes to be present on different chromosomes.
Linked genes are the ones that are present on the same chromosome. Linked genes that are present far apart on the same chromosome may undergo crossing over but the genes present close to each other on the same chromosome are least likely to undergo crossing over. Therefore, the frequency of crossing over increases with increased distance between the genes.
According to the given information, crossing over frequency between genes A and B is 0.1 while that for the genes B and C is 0.3. Since the genes B and C have more crossing over frequency, they are located far apart from each other than the genes A and B. Distance between A and B genes is less than the distance between B and C genes.
