Answer:
The correct answer would be the harmless bacteria had been transformed.
Griffith used two different strains of the bacteria <em>Streptococcus pneumoniae - </em>type-III-S or smooth strain and type II-R or rough strain.
Smooth strain had protective covering around itself (protect itself from hosts's immune system) and was able to kill the mice.
Rough strain did not have any protective covering around itself and thus could be easily removed by the immune system Hence, it was not able to kill the mice.
In addition, heat killed smooth strain was also not able to kill the mice. However, when remains of it was added with rough strain then the blend was able to kill the mice.
Lastly, he was able to isolate living bacteria of both the strains.
He concluded that non-lethal type II-R strain was transformed into lethal type II-S strain by "transforming principle" (which we know today as DNA) that was supposed to be the part of dead III-S strain bacteria.
You know that there is a difference between plant cells and animals cells. The plant cells have a cytoplasm while the animal cells do not. Therefore the answer must be C.
Answer:
There are 3 methods to set up a wildflower classification means discovering a new flower. Those methods are discussed below in the explanation section.
Explanation:
Method one (Identification tools using):
- Search the about of the flower in the flower dictionary or flower database.
- Use any app which can identify flower such as Flowerchecker, Naturegate, etc.
- Take photos of the plant and post it on Flicker to get more information.
- Try google photos for searching about the plant by its picture.
Method two( Measuring the physical character of the plant):
- Measure the overall height of the plant.
- Measuring the width of the plant.
- Look at the flower to check how the flower is arranged on the stem.
- Count the petal number of the flower.
- Identify the color of the petals.
- Check the shape and texture of the stem.
- Check the shape, size, and arrangement of the leaves in the plant.
- Use this collected information to identify the flower in a plant database or encyclopedia.
Method three (Identifying the Flower’s Location and Blooming Time):
- Use the climate and terrain to determine the type of the flower.
- Observation of the factors in the geographic location to identify the flower.
- Find out the time of year when the flower bloomed.
- Identify the flower in an online database or encyclopedia using the collected information.
By doing this, you can set up a wildflower classification key and can find out the kingdom, family etc of the flower.
