Answer:
Physical changes in puberty include: breast development. changes in body shape and height. growth of pubic and body hair.
Explanation:
Water is the main constituent on the earth surface. It is important for all living beings to survive. It is a transparent, odourless, colourless chemical substance. Water has vital role in atmosphere. It undergoes several cycles. In water cycle, water from rivers, lakes and streams enters the atmosphere through Evaporation. In evaporation the element or the compound in it's liquid state changes to gaseous state below the temperature at which the it boils. This is due to the high temperature. Due to high temperature the water from different water bodies enters the atmosphere in the form of vapours. In the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. Transpiration is a process by which the moisture is transferred from roots to the outside of the leaf whic
Therefore, In water cycle, water from rivers, lakes and streams enters the atmosphere through vaporisation. in the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. In nitrogen cycle, the water as well as dead organism moves nitrogen from the atmosphere into the soil.
Answer: (B) Ridge push and slab pull
Explanation: In ridge push, the mantle wells upward because of the convection and elevates the edges of spreading oceanic plates. Because these plates are higher at the spreading center, they are forced downhill due to gravity and eventually flatten out to the ocean floor.
Food Webs <span>show how plants and animals are connected in many ways to help them all survive. </span>Food Chains just<span> follow just one path of energy as animals find food.
So the answer is: Scientists prefer the usage of food webs over food chains due to the fact that food webs are more elaborate and more detailed than the food chain.</span>
The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.
When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.
Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).
The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.
Mole ends=2x(moles DNA)x number of restriction sites.
The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.
Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].
