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.

contrast between mitosis and meiosis

Mitosis

- it takes place in somatic cells in multi cellular organisms in order to provide growth, however, in unicellular organisms it is reproductive division as well. is the means of reproduction in single-celled organisms. Other organisms use it for the growth of tissues (somatic cells)

- exact number of chromosome in offspring

- no recombination or crossing over

- no pairing found

- major phase: prophase, metaphase, anaphase, telophase

Meiosis

- takes place in sex cells to form gamete formation during sexual reproduction

- half of the chromosome number found in gametes of the parents thus, known as reduction division

- due to crossing over takes place recombination  found.

The pairing of chromosomes takes place

- major steps:

Meiosis 1 – prophase, Metaphase, anaphase, Telophase, and

Meiosis 2: Prophase, Metaphase, Anaphase, and Telophase

2. Interphase takes place prior to both mitosis and meiosis which is divided into 3 sub phases-G1, S and G2 phases.

The major events are as follows:

G1- RNA and protein synthesis takes place and cell grows in size

S- DNA replication takes place, Centriole duplication occurs and synthesis of histone proteins.

G2-  RNA and Protein synthesis continues.

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.

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.

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.

Please correct Ok ?

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.

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.

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

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).

The methods the body would use to provide a person with energy throughout a race is using the ATP in the muscle cells for the first 3 seconds.

For the next 8 to 10 seconds, the body replaces the used ATP and produces more.

Within the next 90 seconds of the race, anaerobic respiration is used up to make more ATP (Adenosine triphosphate).

Therefore, during the whole process, the three energy systems used are:

the ATP-PC System

the Glycolytic system

the Oxidative system

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.
