Answer: The correct answer is- A.The plant might have a gene that is similar to a human gene.
Probe can be described as the segment of DNA or RNA (generally 100-1000bp in length) that is designed and radioactively labelled to detect the presence of nucleotide sequences, which are complementary to it.
In this question, the probe is synthesised using sample of human DNA but it also hybridizes with the plant DNA.
This indicates that plant genome has certain DNA sequence or gene that is similar to the gene in the human DNA.
Thus, option A) is the right answer.
Ground water pollution can be caused by chemical spills, road salt, pesticides, fertilizers.
Groundwater pollution also described as groundwater contamination happens when pollutants are discharged to the ground and make their process down into groundwater. This type of water pollution can also happen commonly due to the appearance of an insignificant and unwanted component, contaminant or contamination in the groundwater, in which event it is more likely related to as contagion rather than pollution.
Answer:
true
Explanation:
Viruses are cells with either RNA or DNA.
Viruses are bundles of genetic material enclosed in a capsid.
Both viruses and bacteria are living organisms.
Answer:
Option C. Viruses are bundles of genetic material enclosed in a capsid.
Explanation:
Option A- False - Bacteria is about 100x larger than viruses.
Option B- False - Viruses aren't cells since they aren't living organisms.
Option D- False - Viruses are not living organisms.
Orbital period of mercury can be calculated using the third law of Kepler which states that period squared equals to distance cubed, that is, (T1/T2)^2 = (a1/a2)^3 Where T1 is the orbital period of mercury, T2 is the earth orbital period and is equal to 1 year, that is, 365.25 days. a1 is the mercury axis and is equal to 0.39AU while a2 is the earth axis and is equal to 1AU. T^2 = (0.39)^3 = 0.059319 Therefore, T1 = 88 days.
