With multiple lines of defense including hair, defense mechanisms like sneezing, and various antigens
Answer:
Law of segregation. During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.
option B
Answer:
1st Step: Observation
2nd Step: Questioning
3rd Step: Data Collection
4th Step: Data analysis
5th Step: Communication
In the scientific method, the first step is always to make an observation. You can observe anything in your environment, or a phenomena, or behavior.
The next step would be to question. You form a question to find a possible explanation as to why what you had observed occurred. This is also when you make a hypothesis. An educated guess or a proposal that could explain the event.
After you make a hypothesis, you start an experiment where you will collect data. The data you collect would then be analyzed (4th step). From there you build your conclusion to determine whether your hypothesis holds true.
The last step would be communication. You will communicate the results of your method. This allows people to review your data and process, which may be supported or invalidated. Communication is critical in the scientific world because your results could be the basis for further investigation.
Answer:
Yes
Explanation:
Experimental research includes the manipulation of control variables to measure its impact on the dependent variables.
Both groups are experimental because they both involve the manipulation of control variables. In the given experiments control variable is the light source and the dependent variables is the bending of plant. Both group 1 and group 2, manipulate the control variables that is light source from one direction and light source from direction showing the plant behaviour towards light.
