What was the reaction when the cell theory was first introduced.

Answers

Answer:

Many scientists opposed the "cell theory" when it was first introduced because they believed that even "non-living matters" could produce or generate a living tissue. This was called "spontaneous generation." The appearance of the fly's larva (maggots) on meat supported this belief of theirs.

It was Louis Pasteur who was able to disprove this concept.

Explanation:

The discovery of cell came about when the microscope was invented. It was first discovered by Robert Hooke, an English natural philosopher in the 1600s.  However, he wasn't really sure about the structure and function of the cell during his time. It was Anton van Leeuwenhoek, a Dutch scientist, who proposed that "motility" is a quality of life.

Developing the cell theory was credited to Theodor Schwann and Matthias Schleiden.

Which is a role of helpful bacteria?

removing nutrients from soil

producing oxygen

healing sick animals

preventing tooth decay

Answers

Answer:

Producing oxygen

Explanation:

Bacteria actually add to nutrients in soil because they decompose the organic matter such as dead bodies and such. I do not know if bacteria heal sick animals or if they prevent tooth decay rather I am sure they cause both of those.

Therefore, most plausible answer is producing oxygen because there are bacterias like cyanobacteria, or blue-green algae who go through photosynthesis and produce oxygen which is beneficial for all living beings.

Helpful bacteria helps in producing oxygen for carbon di oxide in th environment. Therefore, option (B) is correct.

What are helpful bacteria?

Probiotics are live bacteria that are beneficial to our health, that help maintain a healthy balance of good and bad bacteria in our intestinal tract, that contribute to the digestion of food and that alleviate digestive issues such as bloating and diarrhea. Lactobacilli and Bifidobacterium are two types of bacteria that are considered to be examples of probiotics.

Through the process of photosynthesis, extremely minute bacteria known as prochlorococcus are busily converting carbon dioxide into the oxygen that we breathe.

Natural selection suggests that creatures with mutations disadvantageous to survival will not live to reproduce, yet there are examples, such as albino animals, found occasionally. Do these exceptions discredit natural selection? Explain your answer.

Answers

Answer:

             yes the above statement is true.natural selection is not dis credit.

Explanation:

                      In order to support my answer we just take an example of mutation in an organism as the mutation in organism occur and is useful for the survival of the organism we called the mutation as the good mutation. Thus it is true that some mutation that cause disease and is disadvantageous for the survival of organism. Albino is a case studied here which is abnormal skin color and the skin color as the advantage to camouflage  in the surrounding and the organism which can not camouflage will not survive properly because the can not protect them from the predator.

The power plant is burning the coal at a rate of 110 lb/s. The efficiency of the powerplant is 33%, which means that 67% of the total energy from the coal is lost as waste heat. a. A new heat exchanger is installed that is capable of using 0.12% of the waste heat to heat an air stream for use in another process in the plant. The air enters the heat exchanger at a volumetric flow rate of 2,000 acfm at 298 K and 1 atm. Assuming the heat exchanger is 90% efficient (i.e., 90% of the heat supplied to the heat exchanger is transferred to the air stream), at what temperature will the air leave the heat exchanger, assuming an exit pressure of 1 atm? Use an average specific heat of 0.244 Btu/lb-R. b. What will be the volumetric flow rate of the gas leaving the heat exchanger (in units of acfm)? c.

Create a class named Billing that includes three overloaded computeBill() methods for a photo book store. When computeBill() receives a single parameter, it represents the price of one photo book ordered. Add 8% tax, and return the total due. When computeBill() receives two parameters, they represent the price of a photo book and the quantity ordered. Multiply the two values, add 8% tax, and return the total due. When computeBill() receives three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and return the total due. Write a main() method that tests all three overloaded methods.
