A benefit of using nuclear energy could be the abundance of uranium in nature. The human risk about mining that is the most important to consider are the health hazards that are associated with uranium mining.
Answer:
Life cycle of a moss
Explanation:
LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE
An embryo further develops into a pear-shaped sporangium, which is the *sporophyte stage of the plant*. The sporangium contains spore sacs, each of which is the spore mother cell that undergoes meiotic division to form four spores,The spores are released and germination
takes place giving rise to a protonema, which develops into a new gametophyte plant. The gametophyte generation or haploid phase of the moss is from the production of haploid spores after meiosis to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid phase is from the diploid mother cells just before meiosis.
Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
"It binds itself to the receptors present on the surface of the cell membrane,which activates the enzymes present inside cell" is the one event that happens next when <span>a peptide hormone reaches its target cell.

Answer:
With the invention of the PCR technique , DNA profiling took huge strides forward in both discriminating power and the ability to recover information from very small or degraded starting samples.
The process of PCR mimics the biological process of DNA replication but confines it to specific DNA sequences of interest.
In PCR process , the DNA sample is denatured into separate individual polynucleotide strands through heating. Two oligonucleotide DNA primers are used to hybridise to two corresponding nearby sites on opposite DNA strands. Thus two new copies of the sequences of interest are generated.
Repeated denaturation , hybridisation and extension in this fashion produce an exponentially growing number of copies of the DNA of interest.
Quantitative PCR methods enable automated , precise and high - throughput measurements.
