Answer:
B) All DNA molecules will migrate up the gel toward the positive electrode.
Explanation:
Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law "force of the interaction between the charges is attractive if the charges have opposite signs".
Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).
You could argue that in early succession areas species may have not been adapted or evolved. In Darwin's theory, life began in a shallow, warm pond. If that is the case, species would then venture deeper when their area they are in is suitable and having success
Answer:
The measures which is taken by country need to prevent global warming are given below.
1) The government of the country should planted more trees because plants are only organisms which reduces the concentration of harmful gases which causes global warming.
2) Reduce the use of fossil fuels such as petrol, coal and methane gas.
3) Use solar energy instead of fuel for the production of electricity and other industrial products.
Answer:
during photosynthesis energy from the Sun is stored in chemical bonds of a glucose molecule
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
- Despite having exons, prokaryotes do not have introns in their genomes.
- This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.
This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.
