Hi, you've asked an Incomplete question. However, I provided a brief about cell theory.

<u>Explanation:</u>

The cell theory basically states that all living things are made of cells and that the cell is <u>the basic unit of life.</u> Robert Hooke, who was a Scientist is known to have originated (coined) the term “cell” in the year 1665.

Basic Facts about Cell theory:

  • the basic unit of life is the cell
  • all living things have one or more cells.
  • already existing cells produce all new cells.

Now, consider the wave function ψ(x)=ceκx+de−κx in the region x&lt;0. as x goes to negative infinity, this must become zero. wha
Mice21 [21]

Answer:

d is zero (0)

Explanation:

ψ(x)=ce^κx+de^−κx

Let say x = - 1000

We have something like

ce^κ* -1000 = approximately zero

Where we assume k to be 1

C becomes zero as it tend to negative infinity

But

If k is 1

de^−1* 1000 =d * 2 * 10^434

To have a zero function d = 0

So 0 * 2 * 10^434 = 0

in a series of experiments Griffith infected mi've with oa nonvirulent r strain bacteria and highly virulent s strain bacteria.
Andrej [43]

Answer:

This demonstrate the transforming principle.

Explanation:

Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did  not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.

When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.

For a scientific theory to be valid, it must allow you to
Cloud [144]

Answer:

Explanation:

That's quite a bit of points. Offer 20 next time (which shows up as 10).

Not all experiments lend themselves to this, but the best ones do. Make predictions. The startling experiments (the best of them) certainly allow you to make predictions

Most of the time, experiments confirm what was originally thought. It is, however, the best answer among this bunch.

A is also possible, but not always. I will stick with D, but I think others will pick A.
