The correct answer is option B, that is, functional group.
A functional group refers to a part of a molecule, which is a classified/recognizable group of bound atoms. The functional group provides the molecule with its characteristics, in spite of what molecule comprises it, they are the centers of chemical reactivity. The functional groups in a molecule require to be determined when naming.
Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms
Q2) Condensation.
Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state
Q3)
Transpiration declines
Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.
Q4) the sun
sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.
Q5) Plants can’t use Nitrogen in the form of N2
N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.
Chromosome is the answer because it is
Nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive
