The answer of the question is
B. Exfoliation
When the entire group of forces acting on an object is balanced, the vector sum
of the forces is zero, and the effect of the group of forces on the object's motion
is identical to the effect of no force at all. The object continues in constant uniform
motion.
To state the outcome of the situation in three different ways:
-- The object's acceleration is zero.
-- The object's velocity is constant.
-- The object's speed and direction of motion don't change.
The direct answer to the question is: Nothing happens to its motion.
Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
Natural fertilizer makes plants grow healthier but artificial fertilizer with chemicals makes it grow faster
Answer:
B
Explanation:
Radiometric dating uses naturally occurring radioactive elements such as carbon-14 within the rock or fossil to estimate its approximate age. The half-life of the element must also be known. The amount of the radioactive trace element is compared to, in a ratio, with that of the number of the decay product elements. This approximate age can then be relatively compared to those of other rocks or fossils.
