There are thousands of bacterial species and they are not identical towards one another, therefore there forms are quite unique. so its just there characteristics that make up how bacteria look like.
Hope this answers your question.
Yes Darwin’s theory of natural selection
Answer:

Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:

Substitue the values into the formula.

Multiply the first numbers together. The grams will cancel.

Multiply again, this time the degrees Celsius cancels.

<u>121.905 Joules</u> are required.
