<h3><u>
Answer:</u></h3>
<u>When scientists report their results from their scientific investigations, scientists should include the content that answers the following questions</u>
- Was our hypothesis correct?
- Do we need to run experiment again,changing a variable?
- If the results did not support the hypothesis then add information about reason why it happened.
<u>Scientists should not include the following </u>
- It should not oppose your results.
- Conclusions should not be in a negative tone.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
I guess the wavelength as the period becomes smaller the wavelength will decrease and frequency will increase all the rest should remain the same
Hope that helps
Answer:
Plasmodesmata
Explanation:
Plasmodesmata are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them. This is the path that viruses use to spread throughout a plant's system.
Hope this helped! :^)
Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
