Answer:
The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do. The second option fits best with Darwin's theory of natural selection, in which he stated that individuals with the most favorable traits are the ones to survive and reproduce, thus passing their traits onto the future population. The first choice incorrectly believes in Lamarck's theory of evolution in which he incorrectly believed that individual organisms in the population developed a trait that would help them survive (e.g. longer necks in giraffes).
Plants are very crucial for maintenance of balance of ecosytem as part of the equilibrium and the primary basis for the ecosystem as the producers.
Explanation:
The ecosystem consists of plants with animals and the environment surrounding it. The balance of all three elements is essential for the co existence of the ecosystem. devoid of any or excess of either factor will lead to destruction.
The imbalance so caused will lead to over production or over consumption of the strata in the ecosystem. Plants holds the producer level of the ecosystem which forms the basis to all, if dis-balanced all the factors relying on it will decline eventually and the world will fall.
Answer and Explantion
Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.
Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.
Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.
Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.
Since, it has a nervous system, blood vessels, and a long digestive tube is most likely a segmented worm.
<h3>What is a segmented worm?</h3>
Segmented worms have long tube-like bodies that are divided into segments.
They are the simplest organism with a true nervous system and blood contained in vessels.
They have a long digestive tube that runs down the length of the worm's inner body.
They can take in dissolved oxygen from the water through their skin.
Thus, a segmented worm has a nervous system, blood vessels, and a long digestive tube.
