Of the steps included in the scientific method, Shameka is performing step five, which is to<u> test your hypothesis by performing an experiment</u>.
The scientific method is the globally accepted process by which to make scientific claims. This method includes seven steps which are:
- Ask a question
- Do research
- Create a hypothesis
- Design an experiment to test the hypothesis
- Perform the experiment
- Study the results and make a conclusion
- Communicate the results to your peers.
The question states that Shameka is <u>gathering samples from nearby water sources</u>, therefore she is in the process of testing her hypothesis through experimentation, which corresponds to step 5 of the scientific design.

B. semi-permeable
meaning: it is only partly permeable, not all substances can pass through the membrane.
Answer:
No.This is because the amount of the chlorophyll; ls not a limiting factor of photosynthesis.
Explanation:
Generally the three factors are regarded as the limiting factors of photosynthesis.These are the CO2 concentration,light intensity,and temperature.Fluctuations in the availability of these factors affects the rate of photosynthesis.
When the rate of a chemical reaction depends on a lot of reactions for its progress.The rate of this reaction is determined or limited by the slowest in the reactions. This series of reactions govern this chemical reactions are the limiting factors. The one that is slowing down the rate of the reaction is said to limit it.
in the case of photosynthesis, a decrease in the amount of CO2,but no change in the amount of other factors would affect the rate of photosynthesis. This is applicable to other factors fluctuation too ,which limits the rate of photosynthesis
The first box is migration
The second box is the northern regions have become warmer because of climate change
Answer:
The trait is Y-linked
Explanation:
The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is <u>Y-linked</u>.
<em><u>Y-linked traits are limited to the Y chromosome only</u></em><em>, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait. </em>
