Hypothesis - Tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation Variable - To vary or change Independent Variable - A manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable (thecause) Dependent Variable - The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables (the effect) C...

Biology LEAP 2025 Review Study Guide with Complete Solutions The steps in protein synthesis (5) 1. transcription; When a copy of one side of the DNA strand is made, which is mRNA. 2. translation; mRNA moves from the nucleus, to the cytoplasm and then the ribosome. mRNA directs the formation of a specific protein at a ribosome, where the code in the mRNA is converted into an amino acid sequence in a protein. 3. mRNA goes through ribosome 3 bases at a time. 4. tRNA matches with the ope...

Natural Selection - Answer-A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. Evidence of Evolution - Answer-1) Fossil Record 2) Embryology 3) Homologous Structures 4) DNA 5) Vestigial Structures common ancestor - Answer-the most recent ancestral form or species from which two different species evolved homologous structures - Answer-Structures in different species that are simila...

The mass of the eggs and the number of eggs produced by sockeye salmon are independent of the females mass. B. The mass of the eggs produced by sockeye salmon depends on the female's average age at reproduction, but the number of eggs does not. C. The number of eggs and the mass of the eggs produced by sockeye salmon depend on the amount of matter stored by ...
