The answer is ‘suspect iii has 900 bp and 260 bp sized DNA fragments’
Forensic science utilizes particular sequences of DNA that are unique to people and are cut differently by restriction enzymes. These techniques are referred to as Restriction Fragment Length Polymorphism (RFLP) and the Short Tandem Repeat (STR) Analysis. In this case, there is an exact match on the crime sample and that of the suspect.
Acute diseases are sudden, severe, and short term only. They quickly appear and worsen without warning and they disappear. Examples of this are flu or colds.
Chronic diseases, on the other hand, are long-developing diseases. The symptoms have been present for long time and it worsens as time progresses. Examples of this are Osteoporosis and heart disease.
No. Deep Brain Stimulation blocks the defective electrical signals that can cause tremors and more movement symptoms.
D.
The block of wood does not stop moving at any time as shown on the chart, so the answer can't be A. or C. and the speed is not increasing so it can't be B.
Answer:
* Glucose may cause an increase in bacterial growth - HYPOTHESIS
* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION
* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION
* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS
Explanation:
In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.
According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:
- Glucose may cause an increase in bacterial growth is a HYPOTHESIS
- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION
- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION
- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS
