Predict the results of genetic crosses
Answer:
The correct option is <em>B) Only triazine-resistant weeds survived and reproduced, so each year more pigweed was triazine-resistant.</em>
Explanation:
With time, the pigweed became resistant to triazine. As we know, according to the theory of natural selection only those species are able to survive and reproduce which are better adapted to live in an environment and adapt to the environmental changes. As the triazine- resistant weeds were better adapted survive and reproduce in the area, it began passing its resistant genes to offsprings. As a result, the population of the pigweed increases.
A Fault or B is the correct answer, faults are when Earth's crust is ruptured or cracken deep below the surface in the crust.
Answer:
This exercise is incomplete, missing the value of k (decay constant), which is equal to 4x10⁻⁸s⁻¹ at 25°C
The answer is 0.549 years
Explanation:
Given:
first order of reaction
k = 4x10⁻⁸s⁻¹
For a first order of reaction, the half-life time for the degradation of DDT is equal to:
