Answer:
<h2>D. Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>
Explanation:
As given here,
The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.
As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.
So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
Answer:
C - a geyser
Explanation:
When underground water and gases are heated by magma, they may shoot up to the surface as mud, water, or smoke, creating some very strange landscapes: Gases rise to the surface and form bubbling muddy pools of decomposed volcanic rock particles and water mixed together.
Answer is C. genome conservation.
A set of DNA, including all of its genes makes up genome of an organisms. Each genome contains all of the information needed to build and maintain that organism. The population of endangered species is small which suffer from reduced genetic diversity through inbreeding.
In conservation genomics, the study of genetic diversity in all genes is carried out for better understand their implications to ecology, health, and disease. This random loss of genetic diversity in diminishing populations is a process known as ‘genetic drift’ and is further complicated by ‘inbreeding depression’, where related individuals breed with each other which results in further loss of genetic diversity.
Using genome editing techniques to carefully reintroduce the lost genetic diversity back into the current, endangered population.
Answer:, microorganisms whose action results in the conversion of nitrates in soil to free atmospheric nitrogen, thus depleting soil fertility and reducing agricultural productivity.
Explanation:
Answer:
Because salt is soluble in water, salt applied to such surfaces dissolves. Liquid water has what is known as a high dielectric constant, which allows the ions in the salt (positively charged sodium and negatively charged chlorine) to separate.
