The texture of a rock is determined by 3 components of the grain: size, shape and pattern.
The rock in your image (although not very clear in your picture) seems to have very large grains as opposed to several coarse grains. Furthermore, the pattern on the rock is uniformly colored and non-banded.
Thus, from what I can discern in the image, the statements that best describe the rock would be:
The grains in this rock are very large and
The rock has a non-banded pattern.
Answer:
b to a
Explanation:
since cells in membranes move from high to low concentration (diffusion). b has more molecules, so it will go into a.
Answer:
<u>III → IV → II → I → V</u>
Explanation:
The first response would be binding of antigenic determinants from pathogen to the receptors on lymphocytes then lymphocytes would become active and they increase their quantity followed by secreting antibodies that will eventually destroy the pathogen. Memory cells will recognize this pathogen as foreign body and they will always remember it.
Solution:
4.2 x 10^6 bp/10^3 bp/seconds = 4.2 + 103 s which is 4200 seconds and equivalents to 70 minutes
In addition, assuming a pause of 2 seconds for re initiating after completing every okazaki fragment and assuming the okazaki fragments average 1000 nucleotide long.
4.2 x 10^6 bp/10^3 bp = 4200 okazaki fragments 4200 * 2 seconds = 8400 seconds which is 140 minutes or 2 hours 20 minutes of pauses alone.
Therefore, overall time would be pauses plus the 70 minutes so total time of 210 minutes. Assuming that the replisome completely disassociates from the DNA after every okazaki fragment and must spend one-minute rebinding.
4200 okazaki fragments. 60 seconds rebinding time per fragment: 4200 x 1 minute = 4200 minutes rebinding time plus 70 minutes for actual replication. 4200 minutes is 70 hours which is almost 3 days.
