What technique is illustrated in this diagram microbiology

Eduardwww [97]

The technique that is known to be illustrated is said to be DNA hybridization.

<h3>What is DNA hybridization?</h3>

In the study of genome, DNA hybridization is known to be a kind of a molecular biology method that is often used to know the measures or the degree of genetic similarity that exist between a given pools of DNA sequences.

DNA hybridization is also seen as ability of two given strand of complementary DNA that tends to pair with another strand and it is one that can be used to find out other similar DNA sequences in two other kinds of species or within a given genome of a single species.

Note that in the case above, The technique that is known to be illustrated is said to be DNA hybridization.

Why is it hard for trees to get water in the winter

nirvana33 [79]

I honestly haven't been in snow but I have of course been in winter.

It is hard for trees to get water in the winter because it hardly rains because the cloud are all covers with white and is cold so it is hard for the clouds to get rain in them and pour it out.

I hope this helped! :D

What is the sum of the complex numbers 6+2i and 3+5i, where i=sqrt(-1)

m_a_m_a [10]

Answer:

The sum of the complex numbers is $9+i\,7$ .

Explanation:

Let be $u = 6 + i\,2$ and $v = 3 + i\,5$ , the sum of the complex number can be found by algebraic means. That is:

1) $u = 6 + i\,2$ , $v = 3 + i\,5$ Given.

2) $u+v = (6+i\,2)+(3+i\,5)$ Definition of addition.

3) $u+v = (6+3) + (2\,i + 5\,i)$ Commutative and associative properties.

4) $u+v = 9 + (2+5)\,i$ Definition of addition/Distributive property.

5) $u + v = 9 + i\,7$ Definition of addition/Commutative property/Result.

The sum of the complex numbers is $9+i\,7$ .

the height of a bottle rocket, in meters, is given by the function s(t)=−9t2+103t+403. find the average velocity of the bottle r

zaharov [31]

The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

The given parameters;

s(t) = -9t² + 103t + 403
time interval (4.499, 4.5), and (4.5, 4.501)

The average velocity of the bottle rocket over the intervals is calculated as follows;

when the interval = [<em>4.499, 4.5</em>]

$s(4.499)= -9(4.499)^2 + 103(4.499) + 403 = 684.22 \ m\\\\s(4.5) = -9(4.5)^2 + 103(4.5) + 403 = 684.25 \ m$

$v = \frac{\Delta \ s}{\Delta \ t} = \frac{684.25 - 684.22}{4.5 - 4.499} = 30 \ m/s$

when the interval = [<em>4.5, 4.501</em>]

$s(4.5) = -9(4.5)^2 + 103(4.5) + 403 = 684.25 \ m\\\\s(4.501) = -9(4.501)^2 + 103(4.501) + 403 =684.27 \ m\\\\v= \frac{684.27 - 684.25}{4.501-4.5} \\\\v = 20 \ m/s$

The instantaneous velocity of the bottle rocket at time t=4.5;

$v = \frac{d \ s(t)}{dt} = -18t + 103\\\\v(4.5) = -18(4.5) + 103\\\\v(4.5) = 22 \ m/s$

Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

How many different nth roots does a nonzero complex number have?

Reika [66]

The Complex nth Roots Theorem with any nonzero complex number has exactly n ∈ N distinct nth roots.

<h3>What is a non-zero complex number?</h3>

This is the quantity which does not equal zero is said to be nonzero. A real nonzero number must be either positive or negative, and a complex nonzero number can have either real or imaginary part nonzero.

The roots lie on a circle of radius centered at the origin and spaced out evenly by angles of 2π/n.
