Your answer would be, Letter Choice ( A), Major differences were discovered in the structure, and operation of the different Species of Monera.
Hope that helps!!!!! (Answer: Letter Choice (A).
Answer: d. a species is in stable and favorable environments.
Explanation:
Asexual reproduction is a mode of reproduction which can be seen in the simple organisms. A single organism give birth to many offsprings. This process does not requires mates and gamete formation. The sexual mode of reproduction involves two parents of opposite sex. This process requires gamete formation. When the gametes of opposite sex fuse together they form a zygote which is a precursor of new offspring.
Asexual reproduction results in greater reproductive success than sexual reproduction as this process does not require mates to give birth to the offsprings. But the asexually reproducing organisms requires stable and favorable environments for production of large number of offsprings. If the external environmental conditions are unfavorable the organism will not survive and reproduce. Thus the reproductive success will decline.
The correct answer would be A.secondary succession. I hope this helps.
Answer:
This is because ladybugs are replaced by pesticides that are responsible for not only contaminating crops but also for releasing dangerous gases into the ozone layer. Therefore, the use of these insects in crops makes the air more pure or avoids contaminating it with life-threatening pesticides for many living organisms.
The microbial theory of disease or germ theory of infectious diseases is a scientific theory that proposes that microorganisms are the cause of a wide range of diseases. These tiny organisms, almost all too small to see with the naked eye, invade humans, animals, and other hosts. Its growth and reproduction within the carrier can cause disease. "Germ" or microbe can refer to a virus, bacteria, protist, fungus, or prion.
Explanation:
The theory was a scientific discovery made in the second half of the 19th century, demonstrated by Louis Pasteur and that replaced previous explanations for the disease, such as the miasmatic theory or the theory of humors. Although highly controversial when proposed, it is now central to modern medicine and clinical microbiology, leading to such important innovations as the development of the vaccine, antibiotic, sterilization, and hygiene as effective methods against the spread of contagious diseases.
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.
