Answer:

describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides.[citation needed] Beach nourishment is typically part of a larger coastal defense scheme. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.

Answer:

Compatibility issues, No exact volume calculation, high cost of construction etc

Explanation:

Beach nourishment is not a viable strategy to manage beach erosion because of the following reasons -

1. It is very difficult to exactly calculate or evaluate the amount of sand volume that is to be brought from nearby borrowing area

2. The cost of construction and maintenance is extremely high

3. Though it is one of the environment friendly method to cater sand beach losses, yet it disturbs the ecology by disturbing the native flora and fauna of the borrowing land

4. It also causes compatibility issue. The sand transported from other areas may have varying characteristics as compared to the sand in the areas where beach nourishment is to be done. This difference may cause higher level of erosion the next time.

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.

Explanation:

Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.

GaryK [48]

<h2>The correct answer is: Mutualism.</h2>

Explanation:

Mutualism can be defined as a type of symbiotic relationship.
Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
In the given question, some micro-organisms survive in the digestive tract of the cattle.
These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
