Answer:
0.1
Explanation:
pH of ocean has decreased from 8.2 to 8.1, it means by 0.1, which refers that slowly ocean water is moving towards getting acidic and that will be very harmful for marine life and human population as well.
Industrial revolution is one of the main cause of decreasing pH in oceans as it leads to pollution, combustion of fossil fuels and global warming which releases more amount of CO2. Most of this CO2 dissolves into seawater, mix with H2O and form carbonic acid (H2CO3), which is acidic in nature.
Hence, the pH is dropped in the oceans by 0.1.
Carbohydrates
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose).
Carbohydrates are:
<span>1. A source of energy for the body e.g. glucose and a store of energy, e.g. starch in plantsbuilding blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP</span>Monosaccharides
2. Monosaccharides are the simplest carbohydrates and are often called single sugars. They are the building blocks from which all bigger carbohydrates are made.
3. Monosaccharides have the general molecular formula (CH2O)n, where n can be 3, 5 or 6. They can be classified according to the number of carbon atoms in a molecule:
Answer:
there are many steps to be followed while preparing temporary slides for observation under the microscope. Explanation: there is cutting of the tissue into smaller section. This reduces the opacity.

<h3><u>Answer;</u></h3>
Instantly transmitted
All of the information your brain receives is <em><u>instantly transmitted</u></em>.
<h3><u>Explanation;</u></h3>
- <em><u>Brain is the part of the central nervous system</u></em> together with the spinal cord.
- <em><u>Brain receives from sensory neurons, which carry stimulus, which are the changes in the environment, from the receptors for processing and interpretation.</u></em>
- <em><u>Brain inter-prates and process information it has received instantly and sends a response via the motor neurons, which carries the responses to the effector cells such as glands and muscles which trigger various actions.</u></em>
