The species-area relationship in island biogeography indicates that larger habitat size reduces the probability of extinction. Habitat heterogeneity provides suitable niches to colonize, thus allowing for a higher number of species in the area. Therefore, the correct option is c.

Habitat heterogeneity provides suitable niches to colonize. Let's discuss the given options one by one.a. Large islands that are far get more species that can fly or swim: This option is incorrect because the number of species on an island is not determined by how far it is from the mainland but instead by the size of the island. Large islands increase the probability of extinction: This option is incorrect because larger islands provide more suitable habitats for a higher number of species and not for increasing the probability of extinction Smaller habitat size reduces the probability of extinction: This option is incorrect because smaller habitat size provides a lower number of suitable niches and habitats to colonize, which can increase the probability of extinction.

Thus, it can be concluded that habitat heterogeneity provides suitable niches to colonize in island biogeography.

The population of beetles in the next three generations, considering the carrying capacity, is y1 = 130 beetles, y2 = 130 beetles, and y3 = 130 beetles.

The population of beetles can be calculated using the formula: y = y0 * (1 + r)^n, where y is the population at a given generation, y0 is the initial population, r is the intrinsic growth rate (expressed as a decimal), and n is the number of generations.

Given that the initial population (y0) is 60 beetles and the intrinsic growth rate (r) is 150% (or 1.5), we can calculate the population for the next three generations.

For the first generation (y1), we substitute y0 = 60, r = 1.5, and n = 1 into the formula: y1 = 60 * (1 + 1.5)^1 = 60 * 2.5 = 150 beetles.

For the second generation (y2), we substitute y0 = 60, r = 1.5, and n = 2 into the formula: y2 = 60 * (1 + 1.5)^2 = 60 * 6.25 = 375 beetles.

For the third generation (y3), we substitute y0 = 60, r = 1.5, and n = 3 into the formula: y3 = 60 * (1 + 1.5)^3 = 60 * 15.625 = 937.5 beetles.

However, since the environment can only sustain a maximum population of 130 beetles, we need to consider the carrying capacity.

To find the population at each generation while considering the carrying capacity, we compare the calculated population with the carrying capacity and use the smaller value as the population.

For y1, the population is 150 beetles, which exceeds the carrying capacity of 130 beetles. Therefore, y1 = 130 beetles.

For y2, the calculated population is 375 beetles, which is also above the carrying capacity. Thus, y2 = 130 beetles.

For y3, the calculated population is 937.5 beetles, which is still above the carrying capacity. Therefore, y3 = 130 beetles.

Old-field succession is an illustration of secondary succession. When agriculture is neglected, it happens. Weeds spread out and soon take over the land when cultivation stops.

Primary succession takes place in a habitat that has never supported life. In a region that was formerly populated but underwent a disruption, such a wildfire, secondary succession happens.

After a significant disturbance like a severe flood, wildfire, landslide, lava, or human activity, animals and plants will recolonize a habitat in a process known as secondary succession.

Primary succession can take tens of thousands of years. The climax communities of an environment can be restored through the process of secondary succession in as little as 50 years. During secondary succession, wildlife in the ecosystem are formed more rapidly.

The emergent layer is unique to tropical rainforests

Explanation:

Tropical rainforests are rainforests general found in areas around the world in which there is no dry season. Each month in these regions has an average precipitation of at least 60 mm.

Temperate Deciduous Forest exists in temperate regions.

The major difference between the tropical rain forest and the temperate deciduous forest is the presence of an emergent layer in the tropical rain forest.

The emergent layer of a tropical rain forest is characterized by a small number of very large trees. These trees mostly grow above the height of the general canopy layer.

Approximately 0.05 g/m of carbon will be passed from the grasshopper to the decomposers.

The amount of carbon that will be passed from the grasshopper to the decomposers can be calculated using the trophic level transfer efficiency model. This model states that only 10% of the energy and biomass is transferred from one trophic level to the next. Since carbon is a component of biomass, we can use this model to estimate the amount of carbon that will be transferred.
Assuming that the grasshopper has a biomass of 1 g/m, only 10% of this biomass will be passed on to the decomposers when the grasshopper dies. Therefore, the amount of carbon that will be passed on can be calculated as follows:
Carbon transferred = (10% of grasshopper biomass) x (carbon content of grasshopper biomass)
Assuming that the grasshopper biomass has a carbon content of 50%, the carbon transferred can be calculated as:
Carbon transferred = (10% of 1 g/m?) x (50% of 1 g/m?) = 0.05 g/m?

Explanation:

The FALSE statement among the given options is: "Once a cell decides to enter the cell cycle, the time from start to finish is the same for all eukaryotic cell types."

In reality, the duration of the cell cycle varies among different eukaryotic cell types due to factors such as cell size, function, and specific cell requirements.

An unfavorable external environment can indeed cause cells to arrest in G1, allowing cells to respond to unfavorable conditions and prevent damaged or stressed cells from undergoing division.

The p53 checkpoint pathway, a crucial component in maintaining genome integrity, can be activated in G1, S, or G2 phases of the cell cycle. Activation of this pathway can lead to cell cycle arrest, allowing cells to repair DNA damage or, in cases of severe damage, undergo apoptosis (programmed cell death).

Lastly, mitogens stimulate cell division by releasing the molecular brakes that keep cells in the G0 or G1 phase of the cell cycle. These growth factors help regulate cell proliferation and drive cells to progress through the cell cycle, ensuring proper cell growth and division.

Sex is a biological trait that refers to the observable physical and genetic characteristics that distinguish males from females. It is frequently assumed that sex is based on biological or genetic characteristics rather than social and cultural aspects.

The physical variations between males and females, such as genitalia and breasts, are some examples of sex differences. Thus, it is a biological characteristic rather than a social one. Both social constructionism and biological determinism, on the other hand, have opposing perspectives on gender. Biological determinism emphasizes that gender differences are inborn, while social constructionism emphasizes that they are socially produced. According to the social constructionism perspective, gender identity and the roles associated with it are the product of socialization and cultural expectations, whereas biological determinism focuses on innate biological differences and the impact of biology on gender.

The claim that sex is a biological trait and not socially constructed can be supported by two course materials. The article "Sex as Biological and Gender as a Social Construct" by Anne Fausto-Sterling argues that sex is a biological characteristic because it is based on genitalia and chromosomes, while gender is socially constructed. This article suggests that sex is primarily concerned with physical characteristics, while gender is linked to social and cultural expectations, which is consistent with the idea that sex is biological and gender is social.
