Answer:
The correct hypothesis would be -
"if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"
Explanation:
The hypothesis is always based on a question one wanted to answer. The hypothesis is the possible explanation of a world natural problem. One needs to make his hypothesis on the basis of the research he made.
To test the hypothesis one needs to develop an experiment like here formed an experiment to test if the light is required for the germination of seeds. Thus, hypothesis would be "if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"
The answer is: 25
Explanation:
#25 is the atomic number for Manganese (Mn).
Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
I believe the answer is gene splicing
Genetic variation occurs.
Mutations are not copied over and over again.
