Identify the plasmid that must contain the CD3γ core promoter sequence but the fewest or no negative regulatory sequences. Based
on the data in Figure 2, describe the most likely cause of the variation in luciferase activity among the cells that contain plasmids pCD3γ-419 , pCD3γ-309 , pCD3γ-239 , and pCD3γ-199 . Calculate the approximate percent increase in luciferase activity between cells containing plasmid pCD3γ-59 and cells containing plasmid pCD3γ-149 . Round to the nearest whole number.
D. ) warm fronts are associated with clouds, showers, and thunderstorms
The warm fronts are the fronts that gradually replace the cold fronts. They tend to warm and moist. Their warmth and humidity comes from the place of their formation, which is above the large bodies of water in the lower latitudes. Because they are warm and moist, the warm fronts bring in warmer weather conditions, but also lot of clouds, intensive precipitation, and very often thunderstorms as well. In most cases, the direction of movement of this type of fronts is from southwest to northeast.
Now, Kurzgesagt does an amazing video on this (and yes, I know mods dont like links very much) : https://www.youtube.com/watch?v=wNDGgL73ihY
I will explain as best I can. So, lets assume that the big bang theory actually happened for right now before any debates arise. First of all, we have no clue what even started it. There are so many theories as to why it started and was their a universe before the big bang.
Now, this is the interesting part. Every universe has its own laws. We have four laws or forces in ours that we know of (and then we have quantum physics which completely messes with physics but we wont get into that).
The Force of Gravity
The Strong Force
The Weak Force
The <span>Electromagnetic Force </span> We have no clue if there are any other universes and if they are, do they have different properties. If so, chemical bonding could be completely different.
So much could be different.
Now, we know there are also some laws like conservation of energy and law of balance. Balance is what made the universe. Atoms had to find their "mate" lets just say and create chemicals. These chemicals would then go on to bind more and more and create other things over time as the universe was also expanding.
The universe is still expanding (and even accelerating its expansion).
Things must be chemically stable and thats how bonds are formed.
Now, this also kinda opens up "why" and science does not always answer "why". Thats more for religion or philosophy.
Its very interesting and I suggest you look into the video I linked.
The variable region limits the
antibody's specificity, otherwise known as the unknown effector function.
It<span> identifies the class or isotype of the antibody between
an anti-pollen IgM, IgE, and IgG. However, the constant domain in the light
chain does not regulate the function.</span>
