European rabbits were introduced into australia and quickly spread, reproduced, and became a terrible pest. they eat up to $600

million worth of food and pasture crops annually, and have damaged the populations of many native plants and the populations of animals that eat the plants. twice in the past 50 years, rabbit diseases have been introduced to try to control the population, with some success. this is a case where ________.

This is a case where AN INVASIVE SPECIE HAS REDUCED THE GENETIC DIVERSITY OF INDIGENOUS SPECIE.
An invasive specie is an animal specie that is brought from another ecosystem and is introduced to a new ecosystem. Such invasive species may throw their new habitat into an imbalance as a result of the manner in which they interact with the components of the ecosystem that has been existing in the ecosystem before and that is what happen in the scenario given above.

If a hemoglobin molecule comes into close contact with a respiring cell, the presence of CO2 in the environment will cause hemog
lapo4ka [179]

Answer:

No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.

Explanation:

The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.

What’s the difference between alleles that are codominant and those that are incompletely dominant?
gulaghasi [49]

Answer:

Codominant- when both are expressed like in flower red and white are codominant so they mixes to get a pinks flower.

Incomplete Dominants- is when a where cow and brown cow mix the offspring are brown with white patches

Identical population-splitting events occurred simultaneously on two neighboring islands, Islands B and C, which are each initia
sweet-ann [11.9K]

Answer:

This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.

Explanation:

  • Due to splitting of the population,
  • The sub-population of rodents formed in Island B are B1 and B2.
  • The sub-population of rodents formed in Island C are C1 and C2.
  • In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
  • In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.

torisob [31]

Answer:

the process described in the question, described by Alessandro Volta refers to superconductivity, in which two metals connected by a conductive liquid produce a continuous transfer of electrons, these metals are considered superconductors since they do not have electrical resistance and this is always maintained and when the temperature is adequate, different from terms such as the resistance that is the impediment to the flow passage, or to the electric static in which the energy accumulation is maintained without movement or transfer or the electric current that is the energy in the same metal.
