The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypic outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents. The Punnett Square is a visual
<span>At the top of plant shoots or roots of plants is an organism called meristem. This organism produces auxin, which causes the shoot or root to grow. This shows that by pinching off the tops of the plants, it makes them grow more.</span>
drag the labels of group 1 to their respective targets to identify the types of sugars and the type of reaction shown .Disaccharide is created when a monosaccharide undergoes a dehydration event (loses water).
nomenclature and structures
The word "carbohydrate" refers to the majority of simple carbohydrates, which have the general elemental composition Cx(H2O)y. It is derived from the German "kohlenhydrate" and the related French "hydrate de carbone." According to the following imbalanced equation, their composition is related to the fact that they are created by photosynthesis from carbon dioxide and water:
Sugar + O2 + CO2 + H2O
The vast majority of naturally occurring carbohydrates present in living things, however, do not have the straightforward empirical formula Cx(H2O)y. Instead, the majority of naturally occurring carbohydrates are composed of oligomers (oligosaccharides or polymers (polysaccharides [Chapter 4]) by combining sugars with the other components of other molecules monosaccharide.

Together, inhalation and exhalation are referred to as breathing. Inhalation is the process of breathing where air moves into the lungs through the nose and the mouth. This causes an increase in the volume of air in the lungs, meaning the pressure will decrease, thus the air then moves to the lungs. Exhalation on the other hand is the flow of the breath out of an organism, for example in humans it is the movement of air from the lungs out of the airways, to the external environment during breathing.
