The best summary of the process of natural selection will be provided bythe option D that is genes are always passed from parent to offspring . Hence , out four inheritance is one of the option in the given question that is gene are passed from parent to offspring .
Answer:
Option B, ionic bonds; salt
Explanation:
All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation
So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.
These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs
Hence, option B is correct
Answer:
Explanation:
Over the past 250 year or two and a half centuries fossil fuels have been burnt at a very fast rate to meet the various human needs. These fossil fuels contains huge amount of carbon dioxide. And when these fossil fuels are burnt in power factories, power plants, cars etc. carbon moves from the fossil to the atmosphere. And since carbon dioxide is a greenhouse gas it traps more heat and hence there is a global temperature rise.
It is estimated that every year almost five and a half billion tons of carbon is released by burning fossil fuels. And since this amount of carbon dioxide is very huge for plants to convert all of them into oxygen via photosynthesis it leads to disbalancing in the carbon cycle that is more carbon dioxide is produced than the amount can be utilized which finally leads to rise in Earth's temperature as all of the extra carbondioxide ends up in Trapping more sun light.
The plants absorb light energy into chemical energy. This energy is used by the plant for fuel. The byproduct of photosynthesis is Oxygen. That is why plants are so beneficial for air quality
