The answer is Scientific thoeries are a culmination of many scientific investigations drawing together all current evidence.

Explanation:

Individuals of a fish species living in a river have varying oxygen level requirements,causing oxygen levels in the water to decrease, directional selection has taken place in this population.

In a population, directional selection occurs when individuals with features on one side of the mean survive longer or reproduce more frequently than those on the other. Natural selection known as directional selection occurs when one extreme phenotype is selectively favored. In other words, those who possess this feature have a higher chance of having children. The chemical element with the atomic number 8 and symbol O is oxygen in this sort of selection. The extremely reactive oxygen, which belongs to the chalcogen group in the periodic table, is also necessary for surgery and trauma. Infants, the elderly, and pregnant women are vulnerable populations who require oxygen on a daily basis.

Fertilization, the fusion of male and female gametes, has a significant effect on genetic diversity within a species. Each gamete contributes half of the genetic material that will be passed down to the next generation. This process ensures that the offspring has a unique genetic makeup as compared to its parents.

The genes that determine the traits that are inherited from the parents are shuffled in different combinations during fertilization, resulting in different variations of traits in the offspring of a species.Fertilization increases the genetic diversity within a species because it produces offspring that have new gene combinations that were not present in the parents.

This combination of traits can create unique physical and behavioral characteristics that may give the offspring an advantage in adapting to their environment. This genetic variation plays a vital role in the evolutionary process. Some of the offspring will have variations that allow them to better adapt to their environment and have a higher chance of survival, whereas others may have traits that are not advantageous and may not survive to reproduce.

Fertilization plays a critical role in the production of genetically diverse offspring that can help a species to adapt and survive in a constantly changing environment.

Explanation:

The term is "molar mass." It is defined as the mass of one mole of a substance in grams. Molar mass is expressed in units of grams per mole (g/mol) and is numerically equal to the atomic.

For example, the molar mass of carbon is 12.01 g/mol, which means that one mole of carbon atoms has a mass of 12.01 grams. Similarly, the molar mass of water (H2O) is 18.02 g/mol, which means that one mole of water molecules has a mass of 18.02 grams. Molar mass is an important concept in chemistry because it allows us to convert between the mass of a substance and the number of moles of that substance. This is useful for stoichiometry calculations, where we need to determine the amount of reactants and products in a chemical reaction.

When a small square is sectioned off for study and the plants, animals, and other organisms in that section are counted, the study is called a quadrat sampling.

Quadrat sampling is also referred to as quadrat study. In ecological research, it is a method used to determine the number or density of organisms in a certain specific area.

It involves dividing the study area into smaller, equally sized plots or squares called quadrats. The size of the quadrat depends on the organisms being studied and the scale of the research.

The third marble should have a greater mass than either the ceramic or steel marble to have a greater kinetic energy at each point along the track. The size of the marble is not as important as its mass in determining its kinetic energy.

The kinetic energy of an object is directly proportional to its mass and the square of its velocity. Therefore, in order for the third marble to have a greater kinetic energy than either the ceramic or steel marble at each point along the track, it would need to have a greater mass or a higher velocity, or both.

To have a greater kinetic energy than the other two marbles, the third marble should have a greater mass. This is because the kinetic energy of an object is directly proportional to its mass, and the third marble would need to have a greater mass in order to have a greater kinetic energy.

However, it is important to note that the third marble should not be so heavy that it cannot make it through the track, or so light that it does not have enough momentum to make it to the end of the track.

In Crigler-Najjar syndrome, decreased activity of glucuronyl transferase results in increased unconjugated bilirubin and kernicterus in neonates. The correct answer is option (d) Crigler-Najjar syndrome.

Crigler-Najjar syndrome is a rare autosomal recessive inherited disorder characterized by the absence or decreased activity of glucuronyl transferase, an enzyme required for glucuronidation of unconjugated bilirubin in the liver. It causes congenital non-hemolytic jaundice.

Kernicterus is a yellowing of the brain that occurs when bilirubin levels in the blood become very high. Bilirubin is a pigment that results from the normal breakdown of red blood cells. When the liver cannot process bilirubin quickly enough, the result is elevated bilirubin levels in the blood that can cause brain damage, which is known as kernicterus. The activity of glucuronyl transferase decreases in Crigler-Najjar syndrome, a rare inherited disease that affects the liver's ability to process bilirubin. Bilirubin levels in the blood rise as a result of this. This can lead to an accumulation of bilirubin in the brain, causing brain damage and, in severe cases, death.

Therefore, decreased activity of glucuronyl transferase results in increased unconjugated bilirubin and kernicterus in neonates with Crigler-Najjar syndrome.

The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.

Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

It is true that an osteon contains osteocytes, lamellae, and a central canal, and is found in compact bone only.

Compact bone is made up of closely packed osteons, also known as haversian systems. The osteon is made up of a central canal named the osteonic (haversian) canal that is guarded by concentric rings of matrix (lamellae). The bone cells (osteocytes) have been located in called lacunae between the matrix rings.

To provide passageways thru the hard matrix, small channels (canaliculi) radiate from either the lacunae to a osteonic (haversian) canal. The haversian systems in compact bone are packed tightly together just to form what appears to be solid mass. Blood vessels run parallel to the length of the bone in the osteonic canals. These blood vessels communicate with vessels on the bone's surface via perforating canals.

We can predict that approximately 3166 species would occur in the entire 1000-hectare reserve based on the provided data and the species-area relationship.

To predict the number of species that would occur in the entire 1000-hectare reserve, we can use the species-area relationship and the values of c and z provided. The species-area relationship is typically modeled using a power law equation of the form:

\(S = cA^z\)

where S represents the number of species, A represents the area, c is a constant, and z is the slope of the relationship.

In this case, we have log(c) = 0.699 and z = 0.608.

To find the value of c, we need to take the antilog (base 10 exponentiation) of log(c). Therefore:

\(c = 10^{(log(c))\)

\(c = 10^{(0.699)\)

c = 4.997

Now we can use the equation \(S = cA^z\) to calculate the number of species for the entire 1000-hectare reserve. Substitute A = 1000 into the equation:

\(S = 4.997 * 1000^{0.608\)

S = 4.997 * 633.939

S = 3166.40
