In tomato plants, the trait for red-colored fruit is dominant over the trait for yellow-colored fruit. When a red tomato plant was crossed with a yellow tomato plant, only red-colored fruit were produced. Which of these best explains why only red-colored fruit were produced? a. Other plants near the parent plants prevented the yellow-colored fruit from being expressed by the offspring.
b. Only the trait for red color was passed down from parent to offspring, so only the red color was expressed by the offspring.
c. The soil in which the parent plants grew prevented the yellow-colored fruit from being expressed by the offspring.
d. Both traits were passed down from parent to offspring, but only the dominant color was expressed by the offspring

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.

could you go a bit more in depth with you question? it's quite hard to understand. as soon as you do that i will be glad to : )
