Answer:
Variations Within Ecosystems
Ecosystem diversity can be described as a term which is used o describe the changes within an ecosystem and the impact these changes have on the environment and humans.
Variations within an ecosystem can cause genetic drifts. Variations will cause those organisms to survive which are better adapted to survive to the changes which occur in an ecosystem. And the organisms which are not better suited become extinct over a period of time. Hence, this will lead to a wide rise in biodiversity.
The answer is most likely going to be FALSE.
Take a frog, for example, first it is a egg, then a tadpole, then a frog
The two phases meiosis is divided into is Meiosis I and Meiosis II. Because Meiosis is not asexual reproduction is uses sexual reproduction by combining the chromosomes of the mother and father. Since each parent give 23 chromosomes to make the whole 46 a human needs, when the chromosomes come together they create tetrads. these are pairs of replicated chromosomes. There are 2 phases because the first phase separates the tetrads leaving the two sister chromatids. During Meiosis II, the sister chromatids are separated like in Mitosis. Overall, the reason that there are two phases is because the maternal and paternal gametes give replicated chromosomes to the zygote.
The answer is 34% of the trash
The correct answer is "<span>It will perform less than optimally unless the pH was increased."
This is because the curve on the graph shows pH versus reaction rate. If we follow the x-axis (the bottom one) to a pH of 7, it is at an extremely low reaction rate compared to other points of the graph. If we continue along, we see that the reaction rate increases as the pH increases. Therefore, the enzyme will perform less than optimally unless the pH is increased.
Hope this helps, and hope I'm the brainiest! :)</span>
