Future consequences if nothing is done to human trafficking
Answer:
Human trafficking affects victims in all aspects of their lives. Everything from physical and s**ual abuse to torture and the use of drugs to economic exploitation and living and working conditions that are abusive can be a part of the human trafficking process. Unlike most other forms of violent crime, human trafficking frequently results in long-term and repeated trauma. Research and documentation described the physical and psychological effects of abuse on men, women, and children in a variety of exploitative situations. People who have been trafficked are at a high risk of contracting HIV for a variety of reasons. In addition to PTSD and other mental health issues, victims of human trafficking may also suffer from symptoms such as panic attacks, insomnia, irritability, and irritability. According to studies, trauma worsens during the trafficking process and can last long after the exploitation ends. Because of their age, immaturity, and lack of experience, child victims are especially vulnerable to trafficking, to abusive practices that may, for example, stunt their further physical development, and to continued victimization as a result of attachment, developmental, and social difficulties. Third parties may find it difficult to comprehend the behavior of trafficking victims, and victims may find it difficult to comprehend what has happened to them, let alone discuss or explain it to others. Victims may appear uncooperative, irritable, hostile, aggressive, or ungrateful to those around them, including supporters. The stigma attached to them as victims has been shown to have a significant and long-term impact on their lives, including trauma and the possibility of physical rejection by family and community. Human trafficking has long-term consequences for individuals that are complex and dependent on a variety of factors, with no guarantee of recovery. Re-victimization is a common side effect of the experience.

Isle Royale is a remote wilderness island, isolated by the frigid waters of Lake Superior, and home to populations of wolves and moose. The graph shows the populations of wolves and moose in this ecosystem over a 50 year period. Examine the data. Which these statements is supported by the data? Choose ALL that apply.
A) From 1978 - 1982, a decrease in the moose population led to a food shortage for the wolves.
B) An increase in the moose population causes a decrease in the wolf population due to predation.
C) An increase in the wolf population results in a decrease in the moose population due to predation.
please answer quickly
D) A virus infected the moose population in the winter of 1996 that resulted in the loss of over 150 moose.
E) The mid-1990s had an abundance of food and a lower number of wolves, leading to a large population of moose in the area.
A) From 1978 - 1982, a decrease in the moose population led to a food shortage for the wolves.
C) An increase in the wolf population results in a decrease in the moose population due to predation.
E) The mid-1990s had an abundance of food and a lower number of wolves, leading to a large population of moose in the area.
Relationship between moose and wolvesFrom 1978 - 1982, a decrease in the moose population led to a food shortage for the wolves because wolves feed on the moose. An increase in the wolf population results in a decrease in the moose population due to predation. In the mid-1990s the large population of moose in the area occurs due to less population of wolves and more food available.

Five strands of mRNA are depicted here, numbered 1-5. The mRNA sequence labeled number
1 indicates the codons that result from the transcription of the original, unmutated DNA. Identify
the statements below that accurately describe the impacts of the mutations shown based on the
illustrations. Select ALL THREE answer choices that apply.
A). 2 is a silent mutation since the same number of codons are being coded for, resulting in a
protein with intact functionality.
B). 3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's
function is significantly altered.
C). 3 and 4 are missense mutations, with only single changes to the genome that result in single
changes to the protein, whose function is intact.
D).4 is the nucleotide insertion, resulting in a frameshift mutation. The protein's function is
significantly altered.
E). 5 is codon duplication, with three additional bases, which can result in a protein with
significant functionality changes.
Answer:
i think its a,c,e
Explanation:
let me know if its wrong tho
The statement '3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's function is significantly altered' is correct.
What is a mutation?A mutation is a genetic change in the nucleotide sequence, which can be used to encode a protein.
A mutation deletion is the loss of one or more nucleotides of the original sequence, which changes the open reading frame (ORF) of the resulting protein.A synonymous mutation is a nucleotide modification that doesn't change the amino acid that will be added to the protein during translation.In conclusion, the statement '3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's function is significantly altered' is correct (the remaining statements are false or the information is incomplete).

A recent scientific study showed that certain regions of the ocean quickly 5 points
warmed at the end of the last ice age. This warming caused a decrease in
oxygen in those areas of the ocean. If a warming event like this were to
happen again, how would it most likely effect the distribution of aquatic
life?
Aquatic organisms in these regions will be forced to live at ocean depths where
sunlight does not penetrate.
Only the largest aquatic organisms, like the blue whale and whale shark, will be able to
survive in these regions.
These regions would support a large amount of life, so they will attract aquatic
organisms of all sizes.
Few, if any, aquatic organisms will be able to survive in these regions, so they will
become "dead zones!
Answer:
Few, if any aquatic organisms will be able to survive in these regions, they will become dead zones

(c) If the Wakame culture is maintained for an additional 120 days, predict the most likely effect on
the number of cells counted every five days. Provide reasoning to justify your prediction. (2 points)
The most likely effect this will have on the number of cells counted every five days is ;
There will be a decline in the number of cells ( Wakame )Incubation periodAs the incubation period increases the number of cells will start declining as the stationary phase has already been achieved between 25 to 30 days. also as the nutrient in the medium decreases the cells will try to adapt the the starvation which will lead to the decline in the number of cells.
Hence we can conclude that The most likely effect this will have on the number of cells counted every five days is ; there will be a decline in the number of cells ( chlorella )

Answer:
Genes are pieces of DNA (deoxyribonucleic acid) inside each cell that tell the cell what to do and when to grow and divide. Each gene is made up of a specific DNA sequence that contains the code (the instructions) to make a certain protein, each of which has a specific job or function in the body. Each human cell has about 25,000 genes.

Dehydrogenation , which generates NADH.In this step 3-hydroxyacyl-CoA dehydrogenase is used as catalyst.Thiolytic cleavage happens in end in which cleaves the terminal acetyl-CoA group and forms a new acyl-CoA which is two carbons shorter than the previous one.In this process beta-ketothiolase is used as catalyst5.

6. What are the 3 major types of sedimentary rocks?.
Earth Science.
Answer:
5) The different elements present in the different igneous compositions will form different minerals. Rocks with high amounts of iron (Fe) tend to form minerals that are dark in color (such as olivine and pyroxene). As result, mafic rocks tend to be dark in color and felsic rocks tend to be lighter in color.
6) There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.
