Salmon introduction in the great lakes has brought in millions of dollars from sportfishing, yet environmentally it has decreased native fish populations and disrupted spawning.

Fishes that reach a mature or adult size of 25–30 cm are considered to be small indigenous freshwater fish species (SIF). They live in floodplains, ponds, lakes, bears, streams, lowland areas, marshes, and paddy fields in addition to rivers and their tributaries.

Several commercially significant species of euryhaline ray-finned fish belonging to the Salmonidae family that are indigenous to rivers of the North Atlantic and North Pacific basin go by the common name "salmon." The same family also includes trout, char, grayling, whitefish, lenok, and taimen, which are all closely related fish.

The embryo would be a collection of undifferentiated cells because they never get the message that will send them down a determination pathway. Hence, b is the correct option.

Embryonic genes are a set of genes that are active during the formation and development of an embryo. These genes control a wide range of processes, including cell division, differentiation, and the formation of specific structures and organs. Some of these genes, known as master regulatory genes, play a particularly important role in controlling the overall pattern of development.

Regulator genes, as the name implies, aid in the regulation of the expression of other genes; however, not all genes are expressed in all cells or under all conditions.

Typically found downstream of reading frames. Homeotic genes are the fly's master regulatory gland. It governs the pattern of body formation in organisms during their early embryonic development. Homeotic genes eventually give rise to transcription factors, which direct the formation of various body parts.

Based on the number of MN blood group genotypes, they are not from the HW data, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or maybe inbreeding)

In population genetics, the Wahlund effect is the buildup of heterozygosity (ie when an organism has two different alleles at a locus) in a population caused by the structure of subpopulations. That is, if two or more subpopulations are in Hardy-Weinberg equilibrium but have different allele frequencies, the overall heterozygosity is less than if the entire population is in equilibrium. The underlying cause of this population subdivision could be a bottleneck to the geographic flow of genes followed by genetic shifts within the subpopulation.

Genotype frequency:

MM (p2) = 400/2000 = 0.2

MN(2pq) = 1200/2000 = 0.6

NN (q2) = 400/2000 = 0.2

Allele frequency:    

Frequency M = p = p² + 1/2 (2pq) = 0.2 + 1/2 (0.6) = 0.2 + 0.3 = 0.5

Frequency N = q = 1-0.5 = 0.5.

Expected genotype frequencies (assuming Hardy-Weinberg):

MM (p²) = (0.5)² = 0.25

MN (2pq) = 2(0.5)(0.5) = 0.5

NN (q²) = (0.5)² = 0.25

Expected number of individuals from each genotype:

MM = 0.25 X 400 = 100

MN = 0.5 X 1200 = 600

NN = 0.25 X 400 = 100

CHI-SQUARE (X²):

X² = Σ(O-E)²/E

X² = (400-100)²/400 + (1200-600)²/1200 + (400-100)²/40

X² =225 + 180 + 200

X² =630

X² (Calculated) > X² (table), then reject the null hypothesis. Not on HWE.

Therefore, conclude there is a statistically significant difference between what was observed and what was expected under Hardy-Weinberg. That is, the null hypothesis is rejected and concludes that the population is not in HWE. They don't, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or possibly inbreeding).

A DNA codon has the nucleotide sequence TAG. The codon in an mRNA molecule made from this DNA bears the sequence 5'-AUC-3'.

A transfer RNA joins the mRNA codon during the production of proteins. The tRNA anticodon has the nucleotide sequence 3'-UAG-5'. Isoleucine is the amino acid that is joined to the tRNA. Explanation: The sequence of nucleotides that dictate the sequence of amino acids that a protein will have during protein synthesis are found in the mRNA, which is transcribing information from the DNA. In mRNA, codons are triplets of nitrogenous nucleotides that code for an amino acid and mark the beginning and end of protein synthesis. In contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

When exposed to cold temperatures, the human body responds in a variety of ways. The body will attempt to maintain a balance of heat by constricting the blood vessels in order to reduce the flow of blood to the extremities and conserve heat.

The body will also shiver in an attempt to generate heat. The skin may become more pale and the person may experience a decrease in metabolism, which can lead to fatigue.

When a substance is introduced into the blood that makes the fluid in the vascular compartment hypertonic, fluid will be drawn from the cells into the vascular compartment.

What do you mean by vascular compartment?

Vascular compartment refers to a group of tissues and organs that are connected by the circulatory system. It includes the heart, blood vessels, and other organs, such as the liver, kidneys, and lungs. Vascular compartments are important for regulating the distribution of blood, nutrients, and other substances throughout the body.

Hypertonic solutions contain a higher concentration of solutes than the cells, such as a higher concentration of sodium or sugar molecules. This causes molecules to diffuse out of the cells and into the vascular compartment, drawing water with them and increasing the osmolarity of the vascular compartment. This creates an osmotic pressure gradient between the two compartments, which drives fluid from the cells into the vascular compartment.

Thermal pollution refers to any change in a habitat's natural temperature, and it can take many different forms, from the discharge of cold water into nearby streams to the increased temperatures associated with industrial cooling activities disturbing the aquatic ecosystem. Thermal or nuclear power stations, industrial effluents from steel mills, pulp and paper mills, chemical plants, refineries, as well as sewage effluents, are the main sources of thermal heat pollution. The most important condition for aquatic species' survival is the water's ambient temperature. Because temperature increases limit enzyme activity, aquatic plants have a lower rate of photosynthesis. Thermal pollution causes water bodies to become warmer, which reduces the primary productivity and species diversity of aquatic plants. Fish and other species acclimated to a specific temperature range may therefore be killed by the sudden shift in water temperature when a power plant first starts up or shuts down for maintenance or other reasons.
