Which fossils provide information as to the mode of formation of an oxygen-rich atmosphere by about 2 billion years ago?
Answer:
The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).

Corn seeds were germinated (grew and put out shoots after a period of dormancy) in a dark room
placed in the light, 75 of these seedlings turned green. Which conclusion about chlorophyll (the
plants can most reasonably be drawn from this information?
(1 point)
DA. Light is the only factor that controls the production of chlorophyll
.
B. Darkness is the only factor that prevents the production of chlorophyll.
IC Light and vitamins are necessary for chlorophyll production.
D. Light and some other factor are necessary for chlorophyll production.
----Page 2 of 9----
Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

Which mutation below would result in the greatest amount of change in the proteins that code for a particular trait?
(Please help I will reward)
A. inserting three nucleotides
B. deleting three nucleotides
C. deleting one codon
D. deleting two nucleotides
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.

The Ebola virus can often have symptoms similar to bacterial pneumonia, an infection of the lungs. These symptoms include chest pains, shortness of breath, and fever. Which statement best summarizes the differences between these two diseases? (SC.6.L.14.6)a.Viruses can replicate because they are living organisms, while bacteria cannot. b.Viruses are not living organisms, but bacteria are living. c.Viruses can be beneficial to live organisms but bacteria are often infectious. d.Viruses are living organisms, while bacteria are not.
Answer:
Eblow is a terrible thing.
Explanation:
Answer:
I think its, option b) Viruses are not living organisms, but bacteria are living.
Explanation:
The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...
Bacteria can replicate as well, not only virus, so that cannot be a difference
The virus is often the one being more dangerous, there is something called "good bacteria"
A virus isn't living, (for the sake of this answer), and we all know for sure that bacteria is living
So, that's how option b is correct

If the atomic number of an element is 6 and its mass number is 13, how many neutrons
are
contained in the nucleus?
19
8
7
6
Answer:
There will be 7 neutrons in a carbon isotope with an atomic mass of 13.
Explanation:
The number of protons in the carbon isotope will be the same as the atomic number, 6, so if we need an atomic mass of 13 there will be 7 neutrons, as 6+7=13.
If the atomic number of an element is 6 and its mass number is 13, there will be 7 neutrons. Therefore, the correct statement is option C.
What is atomic number?Atomic number is the number of protons found in the nucleus of an atom of a specific chemical element. The atomic number is also equal to the number of electrons orbiting around the nucleus in a neutral atom.
Mass number is the total number of protons and neutrons found in the nucleus of an atom and is represented by the symbol A. The mass number is used to determine the atomic mass of the atom.
The atomic number of an element is the number of protons present in its nucleus, which is 6. The mass number of an element is the total number of protons and neutrons in its nucleus, which is 13. So, the number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.
The formula is number of neutrons = Mass number - Atomic number.
Therefore, there are 7 neutrons in the nucleus of the given element.

if a nutrient were in short supply in an ecosystem, how might it effect an organism
Answer:
Its leads to a deficiency
Explanation:
If a nutrient is in short supply in an ecosystem, it will lead to a deficiency of such nutrient in organisms that are in need of the nutrient.
Such a deficiency can lead to diseases in the ecosystem. If organisms that requires the nutrient cannot find an alternative, it will seriously affect their well being. Such deficiency often lead to very dire consequences for the balance of the ecosystem at large.Due in 1 minute please help

For the last 30 years, human use of fertilizers has had a significant impact on the nitrogen
cycle. Which statement explains how fertilizers impact an ecosystem?
O Fertilizers increase the amount of fixed nitrogen available in the ecosystem.
O Fertilizers decrease the amount of nitrogen fixed by organisms living in the ecosystem.
O Fertilizers kill off important nitrogen fixing bacteria.
Fertilizers decrease the amount of fixed nitrogen available in the ecosystem.
Answer:
It's C
Explanation:
Hope this helped :)))
The fertilizers show a significant impact on the nitrogen cycle as the fertilizers kill off the important nitrogen fixing bacteria which are present in the soil. Thus, the correct option is C.
What is Nitrogen cycle?Nitrogen Cycle is a biogeochemical process through which the nitrogen present in the environment is converted into many different forms, consecutively passing from the atmosphere to the soil to the living organisms and back into the atmosphere after decomposition. It involves several processes including the nitrogen fixation, nitrification, denitrification, decay and putrefaction of the nitrogen compounds.
Intensive fertilization of the agricultural soils of normal soil can increase the rates at which nitrogen in the form of ammonia is volatilized in the environment and lost to the air. It can also speed the microbial breakdown of ammonium and nitrates in the soil which results into enhancing the release of nitrous oxide. In addition to this, excessive use of fertilizers also kills the nitrogen fixing bacteria present in the soil.
Therefore, the correct option is C.

How are cancerous cells different from normal cells?
Answer:
Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.
