Answer:
Steric hindrance in the cis orientation causes the chain to take on a more bent shape. Most natural unsaturated fatty acids are in the cis conformation. As can be seen in Figure 2.327, the cis fatty acids have a more of kinked shape, which means they do not pack together as well as the saturated or trans fatty acids
Explanation:
In the grassland ecosystem, the largest number is of producer in the population.
The ecological pyramid of number is the relationship between the number population at each tropic level, it says about number of producers, and consumer. In the grassland ecosystem the vegetation is dominated by plants and grasses.
In the grassland ecosystem, the number producers or plants which is highest is followed by herbivores (mice), which is followed by secondary consumer (snake) and then tertiary carnivores (eagle) . So that, the upper level of trophic level decreases in number. Hence, in grassland ecosystem, the pyramid of number is upright.

Explanation:
Colonies of blue color are produced by cells with functioning copies of beta galactosidase, while on the other hand, colonies of white color are produced by cells with mutations in the lacZ or in the lacY genes. Lac operon consists of three structural genes, and a promoter, a terminator, regulator, and operator. The structural genes are lacZ, lacY, and lacA. lacZ encodes beta galactosidase, which is an intracellular enzyme that cleaves lactose into glucose and galactose
