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.

What phase is Homologous chromosome paired.

Answers

In metaphase I of meiosis I, the pairs of homologous chromosomes, also known as bivalents or tetrads, line up in a random order along the metaphase plate. The random orientation is another way for cells to introduce genetic variation.

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.

a
the reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration.
b
the products of cellular respiration are the reactants of photosynthesis.
c
the reactants of photosynthesis are the reactants of cellular respiration.
d
the products of cellular respiration are the products of photosynthesis.

Answers

The answer is B. The products of cellular respiration are the reactants of photosynthesis.

Final answer:

The statement 'the products of cellular respiration are the reactants of photosynthesis' explains the reciprocal relationship between these two processes, highlighting the cycle of matter and energy in biological systems. So the correct option is b.

Explanation:

The correct statement about the relationship between the reactants and products of photosynthesis and cellular respiration is that the products of cellular respiration are the reactants of photosynthesis. Photosynthesis uses carbon dioxide and water to produce glucose and oxygen. Conversely, cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).

Statement b of the question, 'the products of cellular respiration are the reactants of photosynthesis,' highlights this reciprocal relationship. By examining the equations for both processes, we can see they are the reverse of each other, signifying their direct connection to the carbon cycle.

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.
