One of the major concerns about seawater desalination is its high expense. Another concern is the disposal of leftover brine from the desalination process back into the ocean, which harms marine life. Discuss whether these two concerns are enough to prohibit the widespread use of desalination as a source of drinking water.
Answer:
Yes.
Explanation:
Yes, these two concerns are enough to prohibit the use of desalination as a source of drinking water because this method is too expensive as well as bad for the marine environment. First, this desalination process is too expensive which is non-economical for the country while on the other hand, it greatly damaged the aquatic animals so this method must be stopped due to its adverse effect on both economics as well as environment.

The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.
What are dihybrid crosses?They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.
In this case, the two traits follow the Mendelian pattern and thus, assort independently.
Hence, the traits and their respective ratios would be:
Brown body, Red eyes - 9/16
Brown body, brown eyes - 3/16
Black body, red eyes - 3/16
Brown body, brown eyes - 1/16

AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

Explanation:
Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.
In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.

What are the functions of DNA?Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most cells of every organism.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases, known as cytosine, thymine, adenine, and guanine.

. The number and type of prey items found in the owl pellet can be the result of the following factors: availability and abundance of prey, the ease or difficulty of catching the prey, and the taste preference of the owl. Create an experimental design that would describe the diets of barn owls while accounting for these factors.
Explanation:
Experimental design based on the factors mentioned
Check for availability of prey in same habitat as the Barn owl
Determine the type of prey available in the habitat because Owls feed mostly on small rodents like mice, vole e.t.c
If there is an abundance of prey, Check for the most common and easy to catch prey for an owl . considering the taste of the Barn owls while carrying out this experiment .
The Barn Owls feed mostly on Field voles to other kinds of rodents. therefore the availability and ease of catching a Field vole should be prioritized if they are readily available in the same habitat with the Barn Owls. if Field voles are not available the Barn owls can also feed on other rodents and smaller birds available .
Conclude your experiment
The diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.
What do you mean by Prey?Prey may be defined as an animal or any other organism that is hunted or killed by another animal for the purpose of food.
Barn owl decides its food on the basis of availability and abundance of prey because in order to survive barn owl checks the presence of a particular prey that are easily available and found in high number. Mostly barn owl prefers small species of rodents like mice, young one of rabbit, and sometimes birds.
Other than this it also depends on how much energy is required to catch the particular prey because if the energy is greater than that of benefit, barn owls eliminate this behavior.
And last barn owls choose those prey that is palatable in nature and have good taste. Bad taste or toxic taste is eliminated in nature.
Therefore, the diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.
