Correct order is: organism, population, community, ecosystem, biosphere.
Answer: The study, by Dr. Tim Brodribb and Dr. Taylor Field of the University of Tasmania and University of Tennessee, used plant physiology to reveal how flowering plants, including crops, were able to dominate land by evolving more efficient hydraulics, or 'leaf plumbing', to increase rates of photosynthesis.
Explanation: The reason for the success of this evolutionary step is that under relatively low atmospheric C02 conditions, like those existing at present, water transport efficiency and photosynthetic performance are tightly linked. Therefore adaptations that increase water transport will enhance maximum photosynthesis, exerting substantial evolutionary leverage over competing species.
The evolution of dense leaf venation in flowering plants, around 140-100 million years ago, was an event with profound significance for the continued evolution of flowering plants. This step provided a 'cretaceous productivity stimulus package' which reverberated across the biosphere and led to these plants playing the fundamental role in the biological and atmospheric functions of the earth.
The correct answer is:
C) Carbohydrates are organic macro molecules that are made up of carbon, hydrogen, and oxygen atoms and are used for energy storage or as structural molecules.
They are commonly found in things such as pasta, sweets, or anything similar, and give a lot of energy that gets quickly burned.
Explanation:
In food science and in several informal contexts, the term "carbohydrate" usually means that any food that's significantly wealthy within the advanced macro molecule starch (such as cereals, bread and pasta) or straightforward carbohydrates, like sugar (found in candy, jams, and desserts)
the main property is flammability
