You hear rumors about an unusual series of four islands in the Tierra del Fuego archipelago of Chile. On these islands, the typical laws of island biogeography theory are reversed such that species colonization rates are influenced by island size, not isolation, and small islands have higher colonization rates than larger islands. In addition, islands close to the mainland have higher extinction rates than islands far from the mainland. Of the four islands in this archipelago, a _____ island _____ the mainland would have the SECOND LOWEST equilibrium number of species.

Answers

Of the four islands in this archipelago, a SMALL island CLOSE TO the mainland would have the SECOND LOWEST equilibrium number of species. Biogeography studies species distribution.

Biogeography refers to the discipline that examines the range of distribution of species and taxonomic groups in a given geographical area over geological time.

The theory of island biogeography is a scientific theory that posits the idea that larger islands exhibit a greater amount of species (i.e., higher biodiversity) than smaller islands.

According to this theory (island biogeography), each island represents a particular unique ecosystem, which is different from other surrounding ecosystems.

Which two atoms form an ionic bond?

Answer : A

Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).

Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.

Thus, the correct answer is option (C).

in what generation does this population reach its carrying capacity

Answers

Answer:

The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.

Explanation:

A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

What is carrying capacity?

The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.

It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.

what does unequal division ensure?

Answers

Answer: unequal divisions by design provides a unique synthetic system capable of making decisions on its future fates and states by selectively utilizing two types of divisions.

Explanation:

Stem cells make decisions on either self-reproduction or differentiation by selectively utilizing equal vs. unequal cell divisions Stem cells reproduce themselves by equal divisions. However, they undergo a one-round of an unequal division to reproduce one daughter stem cell which is identical to the original and to produce the other daughter cell that is destined to differentiate to a specialized cell type, thus differentiating into non-stem cell lineages – the process known as “asymmetric cell division”. The differentiated cells reproduce themselves via equal divisions. Therefore, the ability to control equal vs. unequal divisions by design provides a unique synthetic system capable of making decisions on its future fates and states by selectively utilizing two types of divisions.

Over the last two decades, several synthetic cell division systems were synthesized However, none provided a system where equal vs. unequal divisions could be controlled by design. Hence, we set out to synthesize an artificial cell system where we can control equal vs. unequal divisions by design.
