Answer:
Round-Up
Explanation:
In one experiment the positive controls are used in order to validate the evaluation of the test, which is done in this case to measure the effectiveness of the herbicides. The researchers previously found that the herbicide Round-up controls the herb and has a high effectiveness , making this positive positive control be compared with the experimental results. In a positive control we have the desired effect in this case the elimination of grass.
Hypothesis as the statement is not supported by any facts and is therefor classified as a guess to a future investigation
Answer:
When we compare the feeding of larvae with royal jelly to raise queen bees with turning off the Dnmt3 gene
It can be said that the latter is more effective in terms of the number of queens that can be produced and the energy expenditure is much lower. Well, keep in mind that bee larvae only become queens when they receive large amounts of royal jelly. A royal jelly protein is what activates the mechanisms to be a queen bee, this jelly machinery the nurse worker bees.
Through genetic manipulation, the Dnmt3 gene can be turned off in any larva to produce a queen bee.
Answer:
There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the "constant" variable, which must remain consistent and unchanging throughout the experiment.
