Seymour Benzer used phage T4 mutants, Experimental
evidence that a gene is a linear sequence of nucleotide pairs. Some regions of
chromosomes have "hot spots" for mutations. Benzer's experimental
approach to fine structure mapping of the rII locus. Generated 1612 spontaneous point mutations
and several deletions in rII locus identified two complementation groups, rIIA
and rIIB. Mapped locations of deletions
relative to each other using recombination.
Mapped locations of point mutations relative to the deletions. Tested
for recombination between all point mutations within the same complementation
group.
“Remember, we are ultimately trying to explain how hailstorms form. We now know the air is colder higher up in the atmosphere than it is near the ground, which helps us understand where it might be cold enough for hailstones to form.
Our next step is to figure out why the air up high is colder. Based on what we have figured out from the weather balloon data, if we gathered more data by moving closer to the ground, what do you think we would see in that data?
In addition, if we looked at weather balloon data taken at 12:00 noon instead of 12:00 midnight, what do you think we would see in that data?
Do you think we would see the same patterns? Why or why not?” Hope this helps if not write in the comments maybe I will be able to find other answers that might help you. If helped mark me the brainiest!! THESE ARE QUOTES DO NOT COPY ITS IS PLAGIARISM!!
<h2><u>Answer:</u></h2>
Amid the Ordovician Period, the outside of the earth was drastically unique in relation to it is today. About all life on earth was in the seas. The main land life was as exceptionally crude plants extremely close to the water line of the coasts, presumably greeneries and green growth and were of a non-vascular nature.
The Ordovician Period started with a noteworthy eradication called the Cambrian– Ordovician annihilation occasion, about 485.4 Mya (million years prior). It went on for around 42 million years and finished with the Ordovician– Silurian elimination occasions, about 443.8 Mya (ICS, 2004) which cleared out 60% of marine genera.
The timeframe that occurred 488 to 443 million years back. Amid the Ordovician time frame, some portion of the Paleozoic time, a rich assortment of marine life thrived in the tremendous oceans and the primary crude plants started to show up ashore—before the second biggest mass annihilation ever finished the period.
<span>One reflex reaction to maintaining homeostasis in the body is shivering. In response to cold temperatures, the muscular system moves our muscles quickly to warm them up as a rapid, short term solution for homeostasis. Another example is the withdrawal reflex, which occurs as a response to pain. Pain receptors activated by the painful stimulus activate the motor neurons in the body, which in turn contract muscles to move parts of your body away from the pain.</span>
Answer:
R = 480 Ohm
Yes, the current is steady since the power supply is a constant 12V (comming from the battery).
Explanation:
U=I*R
R = U / I
U = 12 V
I = 0.025 A
R = 12 / 0.025
R = 480 Ohm
