When cool air sinks it forces warm air to rise is a example of convection.
The correct answer is b. no additional nucleotides would be added to a growing strand containing that nucleotide.

Nucleotides without a 3’hydroxy group are called dideoxynucleotides (ddNTD). Dideoxynucleotides are inhibitors of DNA polymerase because after being added in PCR reaction no further nucleotides can be added as no phosphodiester bond can be created (usually 3' hydroxyl group of the previous nucleotide attaches to 5' phosphate of the current nucleotide).</span>
The correct answer is option a, that is, It is sometimes sprayed too far from the crops.
The use of pesticides on crops may exhibit a significant threat to the environment, mainly in and nearby to water sources with sensitive ecosystems, sources area, public drinking water, residential areas, and recreational waters.
Aircraft spray of pesticides takes place from a greater altitude than the ground-based equipment and on a major scale, both of these elements may enhance the threat of spray drift.
I processes that transfer energy over Earth's surface are:
1) Conduction
2) Convection
3) Radiation
4) Latent Heat
Conduction is the transfer of heat from a warmer object to a cooler object through molecular interaction. As the Sun heats the ground, energy from the heated ground is transferred to the atmosphere by conduction.
Convection is the transfer of heat by mass movement of a fluid. Convection appears mostly in liquid and gases because they are free to move around. Heat is transferred upward and outward, away from the heat source, while cooler air is brought to replace the rising air.
Radiation is the final process of heat transfer. The energy received from the Sun, radiation, are absorbed by all objects that in turn radiates some of the energy back to its surroundings in a weaker form of energy called long wave radiation such as heat.
Later heat, also known as phase change, is the heat required to change phases. Example of phase change is water transforms from gas to liquid or solid or vice versa. For water to transform from liquid to gas, latent heat from the surrounding atmosphere is needed. In evaporation, water takes heat from the surrounding air in order to evaporated and become gas.
The right answer is spongy bone (cancellous bone).
In otosclerosis, the new bone blocks the movement of the stirrup, causing transmission hypoacusia. Otosclerosis can also cause perceptive deafness, especially when otosclerotic bone foci are close to scala media. Half of all cases are hereditary. The measles virus may play a role in triggering a genetic predisposition to otosclerosis.
