The answer is skin
The first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.
Answer:
Hi there,
They are connected because both of them find identities to someone. All DNA Profiling is, is using either semen, blood, urine, even a strand of hair to test and find whoever left those categories behind. It is used in forensic science that is where they can find the victim's identity or find the suspect.
DNA Profiling and Blood are the same things, in fact, blood IS part of DNA profiling it helps with the testing process in forensic science.
I hope this helped :)
Answer:
Appropriate Question:-
The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.
Given:-
Mass of woman=m=60kg.
Height=h=3m
Time=t=3.5secs.
To find :-
Here we want to calculate the output for a woman
Here first we should calculate work done first.
work \: done = mghworkdone=mgh
Applying the values,
work \: done = 10 \times 60 \times 3workdone=10×60×3
Work done= 1800Joule.
Now , lets calculate power,
power = \frac{workdone}{time \: taken} power=
timetaken
workdone
Now,
Applying the values ,
power = \frac{1800}{3.5} power=
3.5
1800
Power =514.2857 watt.
Hope it helps u mate .
Thank you .
Answer:
Option B== > Amino acid
Explanation:
KINDLY NOTE that the compound in the question is attached below as a picture.
From the diagram in the picture, the compound contains an aryl group, Amine functional group and a carboxylic functional group. An Amino acid compound is a compound that has carboxyl group and the amine group which makes the answer to the question to be option 'b' that is Amino acid.
Polystyrene has formula like this:(C8H8)n, there is no amine functional group attached and there is no carboxyl functional group either which makes polystyrene not to be the answer. This the same case with vitamin D which has which has hydroxyl functional group and not carboxylic nor does it has amine functional group. Although it has been revealed through series of researches that Amino acid are good solvent for Carbondioxide, the most correct option for this question will be on identifying the correct compounds with reference to their functional groups.
