Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Explanation:
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables
The quickest way for an ant to go from the ground to the tree trunk is by walking straight towards the tree and climbing the tree trunk. Ant will walk straight if it is guided by the pheromone trail left behind by the other ants.
The ant first decides to explore the area for food and threats before taking a decision to walk away from its current location, i.e, the ground. The ant then starts to climb the bark of the tree to reach a higher ground. It does so by leaving a pheromone trail behind. This pheromone trail helps in guiding the other ants towards a possible food source.
Answer:
1. living s strain= mice dies
2. heat killed s strain= mice live
3. living r strain= mice live
4. heat killed s strain + living r strain= mice die
Explanation:
Options
1. living s strain
2. heat killed s strain
3. living r strain
4. heat killed s strain + living r strain
Solution
It is known that S strain of the pneumococcal bacteria has virulent properties and hence it can kill an organism but when this S strain is heated its virulent factor dies and it becomes ineffective. R strain on the other hand does not possess virulent characteristics and hence it does not affect the mice. If R virulent is mixed with heat killed S strain, the new strain is transformed virulent strain which could kill an organism.
Considering above description, the answer would be
1. living s strain= mice dies
2. heat killed s strain= mice live
3. living r strain= mice live
4. heat killed s strain + living r strain= mice die
Answer:
According to the diagram, the correct option is E.
Explanation:
Telophase can be described as the last phase in mitosis as well as meiosis. Telophase is also termed as the fifth phase of mitosis. In this phase, the mitotic spindle gets disassembled. Each daughter cell gets enclosed in a membrane. The chromosomes or chromatids become decondensed. The nucleoli reappear during this process. Two nucleoli form, one for each daughter cell.
Finally, the process of cytokinesis occurs which results in the separation of the two daughter cells.
