Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
the answer is A because restriction enzymes function in cutting strand of DNA at specufic sites
your answer is A because a geometric progression is increased by a factor of 3, therefore 4x3=12 and 12x3=36.
hope this helps!!
Answer:2 the lupine dependent butterflies would disappear.
If the spraying of pesticides will remove all the insects then there will be no insect that will pollinate the lupine flowers. So this will cause removal of lupine species from the environment. And the lupine dependent butterflies will not be able to release their egg on these specific flower and will also disappear from the environment.
The removal of lupine flower from the environment will lead disappearing of these lupine dependent butterflies.
The answer is 44 chickens and 28 rabbits.
We have a system of two equations.
x - the number of rabbits
y - the number of chickens
Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.
Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.
Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
