Sand dunes serve an important purpose by protecting inland areas from coastal water instrusion.They are able to absorb the impact and protect inland areas from high energy storms and act as a resilient barrier to the destructive forces of wind and waves.
Have a lovely day/night ☺️
These characteristics are only present during embryonic development in some chordates. The notochord provides skeletal support, gives the phylum its name, and develops into the vertebral column in vertebrates. The dorsal hollow nerve cord develops into the central nervous system: the brain and spine.

Answer:
Male and female gametes are formed and combine in a moist environment to form a zygote.
Explanation:
The gametophyte of a moss plant bears male sex organ antheridia and female sex organ archegonia.
Sperms, the male gametes are produced within antheridia and the eggs are produced in archegonia.
Both the antheridia and archegonia may be produced on the same gametophyte or separate gametophytes depending on the type of moss.
Haploid sperms are released from the antheridia and with the help of moisture, it reaches to a haploid egg in an archegonium. The female gamete or egg is fused with sperm to produce a diploid zygote.
The zygote later develops into the diploid sporophyte.
The product of the lac z gene is an enzyme, this enzyme do in the bacterial cell that enzyme is known as β-galactosidase, that's an important a part of the metabolism of lactose.
<h3>What are lactose restriction enzyme ?</h3>
When a restriction enzyme along with BamHI is used to reduce the plasmid, it might reduce the circle at one place. The reduce could open up the circle withinside the LacZ gene. This is due to the fact gene cloners have located a bit of DNA that has many limit enzyme reducing in the LacZ gene.
It cleaves (separates) a disaccharide lactose molecule into a ways greater digestible glucose and galactose lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.
