One of the authors of the study, Mark C. Mescher, said that, “One of the interesting things we found was that the plants make choices.” Even more fascinating is the choice of their host plant made by the dodder is essential to their survival. A majority of the time, when given the choice, the dodder will choose a tomato plant over a wheat plant as its preferred host. This is most interesting because wheat plants are a poor host because they lack a plentiful variety of nutrients. It is harder for a dodder plant that is attached to a wheat plant to survive than it is for a dodder attached to a nutrient-rich tomato plant (5). So not only does a dodder plant have the ability to choose between a number of potential hosts, the majority of the time it will also choose the plant that will better its chances for survival.

What biological concept was mendel studying when he crossed pea plants many times over many generations?.
blagie [28]

Answer:

Inheritance Patterns

Explanation:

Mendel was studying how genes are past on to future generations and in what circumstances this can occur. He used pea plants as they multiply and grow quickly allowing him to observe many generations much faster than he would be able to observing humans or even other mammals. He also used pea plants because this way he could control reproduction of his pea plant population to adjust to specific questions he had in terms of his research.

zhuklara [117]

Answer:

The population has evolved because there was a change in allele frequencies.

Explanation:

The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.

The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.

Thus, the correct answer is option (D).
