</span>Sexual reproduction provides genetic variation because the sperm and egg that are produced contain different combinations of genes than the parent organism. Sexual reproduction involves meiosis which is the process of a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.<span>Each resulting cell, or gamete from meiosis has only half the amount of DNA as the parent cell. So in order to form a new organism, two gametes, sperm and egg, must fuse, further mixing the genes to produce more genetic variation.</span>

theres no co2</span><span>Sugar is made through photosynthesis by a chemical reaction within the plant’s cell. Photosynthesis takes place in the chloroplast of a cell. Light is absorbed into the cell by chlorophyll which is located in the chloroplast (an organelle in a plant cell.). The chemical reaction that produces sugar is powered by the sun’s energy. Carbon Dioxide, CO2, is absorbed by the plant through the stomata (small openings on the underside of the plants leaves) and water, H20, which is absorbed through the root hairs are combined together in a chemical reaction, which produces glucose, or the sugar that plants use for energy. The chemical formula for the process is 6CO2 + 6H2O (+ light energy) =C6H12O6 + 6O2.</span>
Answer:
Option C, No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat.
Explanation:
Breaking down of large molecules in to smaller molecules does not signify breaking down of energy stored in it and hence losing all the stored energy.
Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be stored in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.
Hence, option C is correct
Answer:
According to Nutton, we are unable to identify any diseases familiar to us today because we are hampered by the great difference between ancient and modern understanding of the concept of 'a disease'.
The evidence or claim he makes to support this, is in his book "Seeds of Disease" where he states that during the ancient medicine practice, the interpretatation was not held nor rigorously or strict, employing words far looser metaphoric sense, interchangeably with what they had known from Galen instead.
Explanation:
Professor Vivian Nutton specialises in the history of the classical tradition in medicine, from Antiquity to the present, and particularly on Galen. He is currently co-editor of Medical History. Heirs of Hippocrates
, how they exercised their influence, and how they were received and interpreted over the centuries, are fascinating stories. It was taken over and translated into Latin, Arabic, Hebrew and a range of European languages.
His main work has focused around Galen of Pergamum (129–216/7 AD), the most prolific writer to survive from the ancient world, whose combination of great learning and practical skill imposed his ideas on learned doctors for centuries, and, secondly, on the development of medical ideas and practices in the Renaissance of the sixteenth century.
