Answer:
All organisms require sulfur as a macro-nutrient. (Ans. E)
Explanation:
Sulfur is necessary for all living things. It is taken up in the form of sulfate from the soil and sea water by the plants, and algae.
Sulfur is known as the essential nutrient for plant growth. Sulfur playing various important role in plants. About 90% of the sulfur is absorbed by the plants for the purpose of amino acids synthesis, known as the building blocks of proteins. Sulfur is important for the enzyme which is helping in the formation of the chlorophyll molecule. Sulfur is essential for the synthesis of oil crops.
In human body sulfur playing some essential role such as amino acid production which is converting into proteins and producing enzymes. Sulfur is important for insulin production, insulin allow the cells to use glucose as energy. Sulfur is found in most important antioxidant known as glutathione, which helping in the inhibition of oxidation of the other molecules and preventing from cell damage. Collagen provide skin strength and structure, sulfur is important for collagen synthesis as well.

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 early signs of a heart attack occur in 50% of patients that have a heart attack according to the Society of Cardiovascular Patient Care. If the early symptoms are noticed the treatment can be administered to prevent damage to the heart as the most heart damages, 85% occur in the 2 hours following the attack.
