Answer:
Well, to be perfectly honest in my humble opinion, of course without offending anyone who thinks different from my point of view but also by looking into this matter in a different perspective and without condemning one's view and by trying to make it objectified and considering each and everyone's valid opinion, I honestly believe that I completely forgot what I was going to say.
Explanation:
it's hard, i kennat.
Wave of option A has the highest frequency.
Option A.
<h3><u>Explanation:</u></h3>
Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.
In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
Answer:
Explanation:
The total solution formed after mixing the components will be
20 μl + 20 μl + 40 μl + 120 μl = 200 μl
The smallest size tube that will hold the entire reaction is:
Firstly convert 200μl to ml
1000 μl = 1 ml
200 μl = X
X = 200 x 1/1000
X = 0.2 ml
The smallest size tube (from the options provided in the question) is 0.25 ml.
The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.
The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
Answer:
MHC Markers
Explanation:
The function of MHC molecules is to display peptide fragments derived from pathogens on the cell surface for recognition by the appropriate T cells.
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. ... Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
