Some natural processes record the variations in time. For example, the sediments found on the rocks acts to be the great proof of the climate that existed in olden times.
Explanation:
Paleoclimatology is the study of climate records from hundreds to millions of years ago. Information for paleoclimate studies come from natural records. One of the most important natural record from which enormous information about the past climate can be known from the tree ring data. Another source include lake and ocean sediments that are found on the rocks and glaciers.
By measuring the width of Sample of tree rings, sediments , corals and ice, the chemical composition, and physical structure of each layer, scientists can also investigate the conditions present when each layer formed. The data of the natural records can be trusted as these prove to be the greatest source of study of ancient civilizations and how they survived in extreme climatic conditions.
Bacteria reproduces by cell division rather than meiosis.
The right answer is: it affects the excretory function of the organism.
Take the example of chronic kidney disease (CKD).
Each minute, about 1 liter of blood is filtered by the kidney (1/5 of the amount pumped by the heart). Chronic kidney disease (or chronic renal failure) is a serious condition that causes a gradual and irreversible deterioration of the kidneys' ability to filter blood and excrete certain hormones. The excess of water and the waste metabolism products pass less into the urine and accumulate in the body.
Answer:
Pentanol, glucose and fatty acid.
Explanation:
Pentanol, glucose and fatty acid are the three molecules which are present in the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.
