An estimated 5% of bass taken during the competition perish, and a further 23% perish after being released, for a total mortality of 28%. Thus, option C is correct.
What results in decline in number of bass?22 percent of these fish are re-caught after being released. They will experience a further 28 percent mortality rate if they are discovered in another tournament.
According to research, small mouth populations can suffer from angler harvest, flooding, and drought, with the latter having the most negative effects.
Therefore, There would be more minnows in the water. Small fish consume algae in a straightforward food chain, bigger fish eat the smaller fish, and bears eat the bigger fish.

what techniques could be used to demonstrate that a mutation in a man with hemophilia is due to the insertion of an alu element into the coding sequence of the x-linked gene for factor viii, one of the proteins needed for efficient blood clotting in humans?
Therefore, if a guy inherits an X chromosome that has a mutation in either the factor VIII or factor IX gene, they may develop a disease similar to hemophilia. Hemophilia can also affect women, however this is far less common. In these situations, either both of the X chromosomes are afflicted, or one is affected while the other is absent or inactive.
What is Mutation ?A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome.
Mutations that are harmful can result in cancer or genetic diseases. A genetic disorder is a condition brought on by a change in one or more genes. Cystic fibrosis is a human example. A single gene mutation causes the body to create thick, sticky mucus that obstructs digestive organ ducts and clogs the lungs.
Missense, nonsense, insertion, deletion, duplication, and frameshift are just a few categories of gene mutations. The advent of lethal diseases like cancer is one of the main consequences of a gene mutation.
What is Hemophilia ?An genetic bleeding ailment called hemophilia causes the blood to clot improperly. This may result in both spontaneous bleeding and bleeding after injury or surgery. Blood contains a variety of clotting proteins that can aid in halting bleeding.
A moderate form of hemophilia A or B usually results in substantial bleeding after an accident. Additionally, you can have bleeding after an injury if you have hemophilia A or B in its most severe forms. spontaneous bruising of the muscles or joints

in the experiment where the amount of chloroplasts was varied, what do your results show about chloroplast function?
More the chloroplasts, faster the reduction. The direct relationship between rate of DPIP reduction and amount of chloroplasts indicates the dependence of water oxidation/ reduction on active chloroplasts.
Chloroplasts are plant mobile organelles that convert light energy into incredibly stable chemical energy via the photosynthetic system. By way of doing so, they preserve existence on the planet. Chloroplasts additionally provide numerous metabolic sports for plant cells, such as the synthesis of fatty acids, membrane lipids.
They are responsible to carry out photosynthesis, the method of conversion of mild power into sugar and other natural molecules that are utilized by plant life or algae as meals. Additionally they produce amino acids and lipid components which can be important for chloroplast membrane manufacturing.

ADP and ATP both inhibit and activate the allosteric enzyme .
How does the enzyme phosphofructokinase control glycolysis?The ability of to control glycolysis through allosteric inhibition enables the cell to alter the rate of glycolysis in response to its need for energy. For instance, and glycolysis will be inhibited by a high ATP to ADP ratio.
The glycolytic pathway has three main enzymatic control sites. These transitions include the hexokinase, phosphofructokinase, and pyruvate kinase enzymes.

Which characteristic was not advantageous for organisms in the million years after the catastrophic asteroid impact?.
(A) "Large body size" is the characteristic that was not advantageous for organisms in the million years after the catastrophic asteroid impact.
At first, having a large body was a disadvantage. Large animals have a high feeding need and a sluggish rate of reproduction. Larger animals eventually took control of the landscape, much as dinosaurs had done millions of years before. Large bodies are detrimental to organisms since they need less food and room to exist, which increases their viability.

what is the effect of mean arterial pressure in the presence of norepinephrine, vasopressin, or angiotensin ii?
Mean arterial pressure (MAP) is the average arterial pressure throughout one cardiac cycle, systole and diastole.
What is Norepinephrine ?Norepinephrine is secreted by adrenal gland. When amount of norepinephrine is increased MAP also increases. When amount of norepinephrine is decreased MAP also decreases.
Vasopressin is secreted by the posterior pituitary gland. It is released when arterial pressure decreases and there is reduction in cardiac volume. It increases systemic vascular resistance and MAP and reduces heart rate and mean pulmonary arterial pressure in patients.

Concentration gradient is more important in cellular metabolism. They maintain the solute solvent interaction properly.
To maintain a stable concentration, the cell attains an equilibrium of solute solvent. That is they flow from higher concentration to lower concentration to maintain an equilibrium.
Chloride ions (Cl−) are pivotal in neuronal signaling; they permeate through anion channels thereby regulating membrane potential and excitability in neurons. A large proportion of Cl− permeable channels are gated by the neurotransmitters GABA and glycine.

Shira observes that the shape of cell a appears normal, while cell b appears swollen and cell c is shrunken. The apparent shrinking of cell c indicates the reaction of the cell to what?.
The apparent shrinking of cell c indicates the reaction of the cell to hypertonic solution.
A cell will lose volume if it is submerged in a hypertonic solution because there will be a net flow of water out of the cell. If a solution's solute concentration is greater than that of the cell and the solutes are unable to permeate the membrane, the solution will be hypertonic to the cell.

Through the process of countercurrent heat exchange in their legs, they keep their feet from freezing while maintaining a temperature above zero.
An entire foot needs a lot of energy to stay warm. These birds, however, let the foot get close to freezing. Birds use a countercurrent heat exchange system, and blood is still given to the foot. The warm arteries transmit heat to the chilly veins. Heat is maintained in the core very well by this countercurrent heat exchange system.
