In the past, there were various pieces of evidence that were used to dispute the idea of continental drift, which is the theory that suggests that continents have moved over time. These pieces of evidence were put forward by scientists who did not believe in the concept of continental drift.

Explanation:

Here are a few examples:

Lack of Mechanism: One argument against continental drift was the lack of a known mechanism that could cause the continents to move. Scientists questioned how continents, which are large land masses, could shift and change their positions without any clear explanation.

Fixed Continents: Another argument was that continents seemed to be fixed in their positions. Scientists believed that the continents were immovable and had always been in their current locations. They argued that the shapes of the continents fit together like puzzle pieces simply because they happened to look that way, not because they were once connected.

Gravitational Forces: Some scientists proposed that gravitational forces were responsible for the arrangement of continents. They suggested that the distribution of land masses on Earth was due to variations in gravity, rather than the movement of the continents themselves.

Geological Stability: The stability of the Earth's crust was also used as evidence against continental drift. Scientists believed that the Earth's crust was rigid and could not undergo significant movements or changes in shape.

However, over time, new evidence emerged, such as the discovery of mid-ocean ridges and magnetic anomalies, which supported the theory of continental drift. This led to the development of the theory of plate tectonics, which explains how the Earth's lithosphere (crust and upper mantle) is divided into several large plates that move and interact with each other, causing continental drift and other geological phenomena.

Higher enzyme concentrations generally result in increased rates of photosynthesis and respiration.

Enzymes play crucial roles in both photosynthesis and respiration by facilitating various chemical reactions. In photosynthesis, enzymes are involved in capturing and converting light energy into chemical energy. One key enzyme involved is Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase), which catalyzes the fixation of carbon dioxide during the process of carbon fixation in the Calvin cycle. Higher concentrations of Rubisco and other enzymes involved in photosynthesis can enhance the efficiency of carbon fixation and overall photosynthetic rates.

Similarly, in respiration, enzymes are essential for the breakdown of organic molecules to release energy. For example, enzymes such as hexokinase and phosphofructokinase are involved in the early steps of glycolysis, which is the primary pathway for energy production in cells. Higher concentrations of these enzymes can increase the rate of substrate conversion and accelerate the overall process of respiration.

Overall, higher enzyme concentrations in both photosynthesis and respiration can enhance the rates of the respective processes by facilitating the necessary chemical reactions. However, it is important to note that there is an optimal enzyme concentration range, and excessive concentrations may not always lead to proportional increases in reaction rates. Factors such as substrate availability, temperature, and other environmental conditions also influence the overall efficiency of photosynthesis and respiration.

The type of pleura plastered against the space dorsal to (posterior to) the pericardial sac is the parietal pleura. The parietal pleura is a serous membrane that lines the thoracic cavity and covers the outer surface of the lungs.

It is divided into two parts: the costal pleura, which lines the inner surface of the ribs and intercostal muscles, and the diaphragmatic pleura, which covers the upper surface of the diaphragm. The pleural cavity is the potential space between the parietal and visceral pleurae. The visceral pleura, on the other hand, is the pleura that covers the surface of the lungs and is continuous with the parietal pleura.

The pleurae produce a small amount of lubricating fluid that allows the lungs to move smoothly during breathing. This fluid also helps to maintain the surface tension necessary for the lungs to expand and contract efficiently.

To estimate volume of eluate at which the peak will occur for each antibiotic, we need to consider the equilibrium constants (K) and the void fraction of bed. estimated elution volume for lincomycin A is approximately 3.64 liters, while for lincomycin B, it is approximately 3.33 liters.

The equilibrium constant (K) represents the distribution of a solute between the stationary phase (cellulose beads) and the mobile phase (solvent system). A higher K value indicates a stronger affinity of the solute for the stationary phase.

In this case, lincomycin A has an equilibrium constant (K) of 11.0, while lincomycin B has a K value of 12.0. Since lincomycin B has a slightly higher K value, it will have a stronger affinity for the cellulose beads and will take longer to elute from the column compared to lincomycin A.

The void fraction of the bed is given as 0.40, which means that 40% of the total bed volume is occupied by the cellulose beads, while the remaining 60% is the volume available for elution.

To estimate the volume of eluate at which the peak will occur for each antibiotic, we can calculate the elution volume based on their equilibrium constants and the void fraction.

For lincomycin A: Elution volume = Void fraction * Total bed volume / K

Elution volume = 0.40 * 100 liters / 11.0 = 3.64 liters For lincomycin B:

Elution volume = Void fraction * Total bed volume / K

Elution volume = 0.40 * 100 liters / 12.0 = 3.33 liters

Therefore, the estimated elution volume for lincomycin A is approximately 3.64 liters, while for lincomycin B, it is approximately 3.33 liters.

In ecology, density is a measure that refers to how many individuals a population has in a specific habitat.

Considering this, we can say that water is a density-dependent limiting factor, since this is a limited resource that can vary its availability annually, but also is a species have too many individuals, all of them will not have the same capacity to reach this resource, especially when we talk about large animals or plants.

Diseases caused by bacteria would be also a density-dependent limiting factor, since only when too many microorganisms of a pathogenic species replicate in our bodies, do we begin to feel the symptoms of that illness.

Predators are also a density-dependent limiting factor since the species which they feed on can be overhunted by them, being reduced in number of individuals, or being not too much hunted and increase their individuals.

Earthquakes are a density-independent limiting factor, since they do not depend on other factors to occur, but only on the movement of our planet's plates.

Finally, limits population regardless of how many organisms are present in the area is a density-independent limiting factor, since they do not depend on how many organisms they're to limit the increase of the population. Being this option an abiotic kind of non-limiting factor.

Down-regulation of a target cell can occur in response to a prolonged increase in the level of a hormone.Correct option is (b).

Down-regulation is a biological process that occurs when there is a decrease in the number of cell receptors of a hormone that leads to a decrease in cell sensitivity to that hormone and a decrease in the biological response to that hormone.

A biological response refers to the body's response to the presence of a hormone in the body, and it is regulated by the number of hormone receptors present in the cell membrane. Hormone receptors bind with hormones present in the bloodstream and transmit signals to the cell's nucleus for a response.

Therefore, if there is a prolonged increase in the level of a hormone, down-regulation of the target cell can occur. This happens because the cells will reduce the number of receptors to which the hormone can bind. This will lead to a decreased biological response to the hormone.
