D. ; Eukaryotic cells are bigger, younger, and more complex
<u>Answer</u>: works optimally at 20°C
Enzymes are a broad group of biological catalysts that have the role of accelerating chemical reactions by binding to molecules and altering them in specific ways. They are essential to the correct functioning of the body.
Enzymes function only at certain temperatures and pH ranges. The enzyme shown in the graph works optimally at 20°C. This is shown by the fact that the reaction rate, enhanced by the enzyme, reaches a maximum at this temperature. The higher the temperature, the more effective the enzyme.
However, at temperatures higher than this optimal threshold, the enzyme will gradually decrease in efficiency. To high or low temperatures will have this effect.
Phenomena such as star explosions, neutron stars, black holes etc. are studied with the help of extremely powerful and sensitive telescopes.
These sophisticated instruments are able to see more than our own eyes can. Thus, they detect wavelengths outside of those found in our visible spectrum, such as X-rays etc.
The most sophisticated telescopes are those that are placed in space such as the Hubble or Spitzer Space Telescope. In this way, these instruments are able to circumvent the Earth's atmosphere that may block the view of the sky. Thus, in space, they have the optimal conditions to observe and study in detail such phenomena.
Answer:
these illustration show the homologous forelimbs of your different species with enough similarities
Answer: died
Explanation: Simon was dead, and Jack had died. 'Was' is a past continuous tense word showing an action that had been performed moments, seconds, minutes or even years ago, and that action or event will continue to be in the past. 'Had' on the other hand is showing an event that just occured recently. Simon might have died 2 days ago and Jack's death might have come seconds ago.
