Answer:
Carbon dioxide is a gas which is released in the atmosphere as greenhouse gas, burning of fossil fuel, released in respiration process. Rise in the levels of carbon dioxide and other gases has resulted in increase in global temperatures. Increase in carbon dioxide and temperatures are responsible for weather fluctuations and global warming.
Weather fluctuation means untolerated heat and lack of precipitation or rain. Weather fluctuations will affect seasons. Seasons are necessary for maintaining the life cycle of organisms. Inappropriate seasons due to climatic change will affect the life of living organisms.
Global warming is an issue which is mainly due to release of hot heat trapping gases from green house and other sources, increasing the atmospheric temperature. This will result in melting of ice from glaciers in world. The inhabiting animals living in the glaciers will suffer a lot from this as they cannot tolerate warm climatic conditions.
Answer:
A point mutation with occur.
Explanation:
This quesiton might need more info but in general a point mutation will occur.
Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
The investigators could distinguish human hair from animal hair by the patter of pigmentation and by the medullary index.
The pigmentation in human hairs is denser toward the cuticle, whereas in animal hair is denser toward the medulla. Human hairs are usually one colour throughout the whole length, while animal hairs may change colour suddenly.
The medulla in humans is thinner than in animals: the medullary index for human hairs is 0.33 or less; the medullary index for animal hairs is 0.5 or more.
