Duplicated chromosomes are called sister chromatids. The correct option is B.
A chromatid is one of the two identical halves of a replicated chromosome, both of which are joined at the centromere. During the cell cycle, chromosomes are replicated in the S phase of interphase, resulting in the formation of two identical sister chromatids that are held together by a centromere.
The two sister chromatids are virtually identical in every way because they are formed as exact replicas of one another. This happens during the S phase of the cell cycle when DNA is replicated in a cell. Once the chromosomes are replicated, each of the two copies is referred to as sister chromatids because they are still identical to one another.
However, each sister chromatid will later be pulled to the opposite side of the cell during cell division. Duplicated chromosomes, also known as sister chromatids, are unique to eukaryotic cells because they are a result of the way that eukaryotic cells replicate their DNA. Chromosomes are replicated in the S phase of interphase, resulting in two identical sister chromatids that are held together by a centromere.

Water recreation is more active in this area, causing stress to the fish. So correct option is D.
Describe Water Recreation?Water recreation is any activity that involves the use of water for recreational purposes. It can include a wide range of activities such as swimming, boating, fishing, water skiing, surfing, diving, snorkeling, and more. Water recreation can take place in natural bodies of water such as lakes, rivers, and oceans, as well as in man-made structures such as swimming pools, water parks, and water features.
Water recreation can be enjoyed by people of all ages and can be a fun and healthy way to stay active and enjoy the outdoors. However, it is important to engage in water recreation safely and responsibly, as water-related activities can also be associated with risks such as drowning, accidents, and injuries. To ensure safety, it is recommended to follow safety guidelines and regulations, use proper safety equipment, and be aware of potential hazards associated with the activity and the environment.
The most likely explanation for the abnormal fin size of fish in the stream at the edge of the property is that water recreation is more active in this area, causing stress to the fish. Increased human activity such as water recreation can cause disturbances to the aquatic environment and can lead to increased levels of stress on fish populations, which can affect their growth and development. Excessive sunlight or inadequate sunlight exposure may affect fish populations, but it is less likely to cause abnormal fin size specifically. Pesticides entering the stream through runoff may also affect fish populations, but again, abnormal fin size is not a typical symptom of pesticide exposure. Therefore, the correct answer is option D: Water recreation is more active in this area, causing stress to the fish.

describe the steps of translation. what structures are required? how do they interact to make a polypeptide?
Translation is the process by which genetic information encoded in mRNA is used to synthesize a protein. This process involves the use of a ribosome, which reads the mRNA sequence and matches each codon (three nucleotides) with the corresponding amino acid to form a polypeptide chain.
The following are the steps of translation:Initiation: The ribosome binds to the mRNA molecule at the start codon (AUG), which signals the beginning of the protein-coding sequence. The ribosome consists of two subunits, the small subunit and the large subunit, which come together to form the functional ribosome.Elongation: The ribosome moves along the mRNA molecule in a 5' to 3' direction, matching each codon with the appropriate tRNA molecule. Each tRNA molecule carries a specific amino acid, which is added to the growing polypeptide chain as the ribosome moves along the mRNA molecule. The ribosome catalyzes the formation of peptide bonds between adjacent amino acids to form the polypeptide chain.Termination: The ribosome reaches a stop codon (UAA, UAG, or UGA), which signals the end of the protein-coding sequence. At this point, the ribosome releases the completed polypeptide chain and dissociates from the mRNA molecule.Several structures are required for translation to occur, including:mRNA: The mRNA molecule carries the genetic information from the DNA to the ribosome, where it is translated into a polypeptide chain.tRNA: The tRNA molecule carries a specific amino acid to the ribosome, where it is added to the growing polypeptide chain.Ribosome: The ribosome is the molecular machine that reads the mRNA sequence and catalyzes the formation of peptide bonds between adjacent amino acids.Amino acids: The building blocks of proteins that are added to the growing polypeptide chain during translation.These structures interact with each other in a highly coordinated manner to make a polypeptide chain. During translation, the ribosome reads the mRNA sequence and matches each codon with the corresponding tRNA molecule, which carries a specific amino acid. The ribosome then catalyzes the formation of peptide bonds between adjacent amino acids to form the polypeptide chain. As the ribosome moves along the mRNA molecule, the tRNA molecules are released and can be recharged with new amino acids for further rounds of translation. Once the ribosome reaches a stop codon, it releases the completed polypeptide chain, which can then fold into its functional three-dimensional shape.

Heterozygosity refers to the presence of two different alleles at a given gene locus in an organism's genome. In genetic notation, the two alleles are represented by letters, with the dominant allele typically represented by a capital letter and the recessive allele by a lowercase letter.
For example, if the gene for flower color in a plant has two alleles, one for purple flowers (dominant) and one for white flowers (recessive), then a plant with a heterozygous genotype for this gene would have one allele for purple flowers (represented by the letter P) and one allele for white flowers (represented by the letter p).
Now, looking at the six boxes given in the question, we can see that only box D represents a heterozygous genotype. Box D has the letters D and d, which indicates that this plant has one allele for the dominant trait (represented by the capital D) and one allele for the recessive trait (represented by the lowercase d).
Therefore, the answer to the question is: Box D corresponds to plants with a heterozygous genotype.
