3. Synthesize in your own words, explain why scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity Refer to the Case Study.
Explanation:
Scientists give three reasons. First, amphibians are sensitive biological indicators of changes in environmental conditions such as habitat loss, air and water pollution, ultraviolet (UV) radiation, and climate change.Amphibians are sensitive biological indicators of environmental circumstances such as habitat loss, pollution of the air and water, ultraviolet (UV) radiation, and temperature change.
What is biodiversity?The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the genetic, species, and ecosystem levels is called biodiversity.
Biodiversity refers to the variety of all the diverse species of organisms that dwell on our planet, including the plants, animals, insects, and microorganisms.
Each of these things exists in a delicate balance and coexists with the others in ecosystems that nourish and sustain life on earth.
Amphibians are sensitive biological markers of changes in environmental conditions like temperature, UV radiation, habitat loss, and air and water pollution.
Thus, scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity.

When tulips bloom, they are attempting to pollinate using the process of meiosis which part of tulip is related to meiosis? Why do tulips need to under go meiosis?
Answer:
The correct answer is - pistil and stamen.
Explanation:
Meiosis is the type of cell division that takes place only to produce gametes that are megaspore and microspore, in sex cells of the flowering plant. In tulip and other similar flowering plants have ovary at the base of the pistil that contains and produced megaspore (female spores) by meiosis.
Similarly, anthers in the stamen of the tulip flower produce male spores called microspores and contain. Meiosis is essential in sexual reproduction to ensure that each cell has the correct number of chromosomes and responsible for recombination.
During pollination Tulip under meiosis in other to produce the required gametes needed for sexual reproduction. The parts of the Tulip that contains the megaspore and microspore gametes are :
Pistil : The ovary that produces and stores the female spores via meiosis is located at the base Stamen : The anthers which produces the male spores via meiosis is located at the stamen.Also Tulips undergo meiosis to ensure that the cells have the accurate number of chromosomes that is to be used for recombination.

It is mistakenly believed that the rapid evolutionary changes of punctuated equilibrium are the result of some mechanism of evolution other than natural selection, thus seeming to undermine evolutionary theory. This belief is mistaken because:
Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.
Explanation:
The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
