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.
Like all other heterotrophs, it eats and goes through cellular respiration.
It is true, it dissolves during prophase because it is not needed in the following phase of metaphase
Hoarding, it may seem like a complicated question but think it through.... which one of these things doesn't belong... also compare the definition of hoarding to compulsive shopping and you should see similarities.
Plus compulsive shopping patients have tendencies to turn to hoarding.
<span>The answer is osteoid. It begins with unmineralized collagen fibers
and ground substance. Later it becomes a calcified matrix. The matrix is mainly
made of collagen and calcium ions. When not well mineralized, osteoblasts proliferates
hence the bone will not have the desired strength. This results to deformation
of bone causing rickets</span>
