Bioaccumulation is the total accumulation of certain chemicals/contaminants in an organism, coming from diverse sources such as water, air, and diet. Therefore the case of mercury occurs when mercury is accumulated in an organism, for example, fish. The most common pathway for this to happen is through the food chain, nonetheless can occur through abiotic means, an example is in fish, where methylmercury is acquired through the gills.

When methylmercury is absorbed through the gastrointestinal tract & enters the bloodstream and goes rapidly to other parts of the body.

Mercury is a persistent substance, which can bioaccumulate, in living organisms, inflicting increasing levels of harm on higher-order species such as predatory fish and fish-eating birds and mammals through a process known as "biomagnification"

The release of processed mercury can lead to a progressive increase in the amount of atmospheric mercury, which enters the atmospheric-soil-water distribution cycles where it can remain in circulation for years. Mercury poisoning is the result of exposure to mercury or mercury compounds resulting in various toxic effects depending on its chemical form and route of exposure.

The major route of human exposure to methylmercury (MeHg) is largely through eating contaminated fish, seafood, and wildlife that have been exposed to mercury through the ingestion of contaminated lower organisms.

King mackerel, marlin, orange roughy, shark, swordfish, tilefish, ahi tuna, and all contain high levels of mercury.

Human activity is the main cause of mercury release, especially coal-fired power stations, residential coal burning for heating and cooking, industrial processes, waste incinerators, and as a result of mining for mercury, gold, and other metals.

Answer:

The digestive tract of the earthworm and the salamander are similar in some ways, but they also have some differences. Both animals have a simple, linear digestive tract that consists of the mouth, esophagus, crop, gizzard, and intestine. However, the earthworm has a smaller and simpler digestive tract than the salamander.

One of the main differences between the digestive tracts of the earthworm and the salamander is the presence of glands. The salamander has several glands in its digestive tract, including the salivary glands, liver, and pancreas, which produce digestive enzymes and hormones that help to break down food and absorb nutrients. In contrast, the earthworm does not have any glands in its digestive tract, and it relies on the mechanical grinding action of its gizzard to break down food.

Another difference between the digestive tracts of the earthworm and the salamander is the presence of a stomach. The salamander has a muscular stomach that is used to store and churn food, which helps to break it down and mix it with digestive enzymes. The earthworm, on the other hand, does not have a stomach, and it does not have the ability to store food for extended periods of time.

Overall, the digestive tract of the earthworm is smaller and simpler than that of the salamander, and it lacks some of the specialized structures and functions that are found in the salamander's digestive tract.

The correct answer is c. external clock of the AVR. In AVR microcontrollers, timers can be configured to use different clock sources for their operation.

The control bits CS12, CS11, and CS10 in the timer control registers determine the clock source selection.

In this case, if CS12-10=5, it means that the timer is configured to use an external clock source.

The AVR microcontroller can have various clock sources available, including an internal oscillator, external crystal or resonator, or an external clock signal provided by an external device.

When the timer is set to use an external clock, it relies on an external clock signal to provide the necessary clock pulses for its operation.

Hence, the external clock of the AVR is the resource that provides the clock pulse to the AVR timers in this scenario.

As the hunters tend to target the larger animals with big horn, smaller animals with short horns will have better chances of survival so the traits for short animals with short horns will be selected.

The simulator is set to begin examining Nernst potentials related to sodium with these numbers due to the physiological importance of sodium ions in the body.

Sodium ions are one of the major electrolytes in the body and play a significant role in regulating various physiological processes. They are important in maintaining the body's fluid balance, muscle and nerve function, and blood pressure. The concentration gradient of sodium ions is maintained through the sodium-potassium pump, which pumps sodium ions out of the cell and potassium ions into the cell.This gradient is responsible for the resting membrane potential of cells. The Nernst equation is used to calculate the equilibrium potential of an ion. For sodium ions, the equilibrium potential is +61 mV at 37°C. Therefore, if the concentration of sodium ions is higher outside the cell than inside, sodium ions will tend to move into the cell, leading to depolarization and the initiation of an action potential. Understanding the Nernst potential related to sodium ions is crucial in understanding the mechanisms underlying nerve and muscle function.

Explanation:

The grasshopper is the primary consumer so it is herbivore.

In order to determine which birds belong to the same species, the trait that is most commonly used is their ability to interbreed and produce fertile offspring. This trait is known as reproductive compatibility or reproductive isolation.

If two birds can successfully mate and produce viable offspring, they are considered to be members of the same species.

Reproductive compatibility is a crucial factor in species classification because it reflects the genetic similarity and evolutionary relatedness between individuals. Birds that are closely related and share a recent common ancestor are more likely to be able to interbreed and produce fertile offspring.

Other traits such as physical appearance, behavior, vocalizations, and genetic analysis can also be used to support species identification. However, reproductive compatibility remains one of the most reliable and fundamental criteria for determining species boundaries.

It's important to note that species classification can sometimes be complex, especially in cases where there is variation within a species or when closely related species exhibit hybridization. In such situations, scientists may rely on a combination of traits and genetic analysis to determine species relationships.

The best question to ask to determine the effects of breeding the grey peacocks  is: Are there any negative health effects associated with breeding only grey peacocks?

Breeding of peacocks involves the mating of a male peacock with a female peahen. During the breeding season, the male peacock displays its ornate feathers to attract a mate. The female peahen selects a male based on the quality of his display, and the pair mate. After mating, the female peahen will lay a clutch of eggs, which will hatch after about a month. The resulting offspring will inherit genetic traits from both parents. Breeders may also use selective breeding techniques to produce desired traits in their peafowl, such as the gray coloration in the example you mentioned earlier.

Answer:

A. dominant

Explanation:

Answer:

The correct answer is -50%

Explanation:

Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele

So, the heterozygous woman will be - Pp & the normal man will be - pp.  The presence of one allele of polydactyly will be able to show its effect as it is dominant.

Cross between heterozygous woman & normal man:

Gametes:

   P                              p

p Pp (Show polydactyly) pp (Normal phenotype)

p Pp (Show polydactyly) pp (Normal phenotype)

From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.

Polydactyly is a condition that occurs wherein individuals have more than the normal amount of fingers and toes. It is also a genetic condition and as well heritable.

The probability of producing an offspring with extra toes or fingers in a cross between an heterozygous and a normal is 50%.

Let P represent the dominant and p the recessive

Pp (heterozygous) and pp (normal)

 (woman)      P        p

 (man) p     Pp        pp

           p     Pp        pp

                  50%      50%

Therefore, the probability of producing an offspring with extra toes or fingers (Pp) is 50%.

The event that leads to increased airflow is b. bronchodilation caused by using an inhaler to treat asthma.

The event that leads to decreased airflow is a. decreased levels of surfactant.

When inhaler relaxes the bronchial muscles which allows the airway to open, thus increasing airflow. Surfactant is a substance produced by the cells in the alveoli of the lungs and helps to reduce surface tension in the airways. When surfactant levels are reduced, surface tension increases, making it harder for the lungs to expand and decrease airflow.  

Aerobic exercise which improves pulmonary compliance does not necessarily lead to either increased or decreased airflow. Pulmonary compliance is the amount of change in lung volume relative to the amount of pressure needed to cause that change. Aerobic exercise helps to make the lungs more compliant, but the actual effect on airflow is unclear.

Breathing sub-zero air, an anaphylactic reaction caused by bee sting, and scar tissue from tuberculosis all lead to decreased airflow. Sub-zero air is much denser than normal air, which makes it harder for the lungs to expand and thus decreases airflow. An anaphylactic reaction caused by bee sting causes inflammation in the airways and makes it difficult to breathe. Scar tissue from tuberculosis reduces the amount of air that can enter and exit the lungs, thus reducing airflow.
