Hello, Miss Shelton.
- 00:01 - 00:06
And hello to whoever else is watching this, um, something
- 00:07 - 00:09
before I get into things, I just have to say
- 00:10 - 00:12
I'm not going into great detail, but I will explain
- 00:12 - 00:14
as much as I can in this video.
- 00:16 - 00:22
We're going to be talking about levels of organization, and
- 00:24 - 00:26
after this we'll be talking about stem cells.
- 00:28 - 00:28
Now level the organization.
- 00:29 - 00:30
There will be two parts.
- 00:31 - 00:32
They'll be fast and simple.
- 00:34 - 00:35
So now we'll get the part one.
- 00:37 - 00:41
This are part this These are the beginning off levels
- 00:42 - 00:42
of organization.
- 00:44 - 00:46
As you can see, we start from Adam toe organism.
- 00:47 - 00:52
So Adams atoms are are mostly found in chemical elements
- 00:54 - 00:56
or they are part of chemical elements.
- 00:57 - 01:02
Now molecules when a group of atoms group up two
- 01:02 - 01:08
molecules or become molecules now molecules as an example, uh,
- 01:10 - 01:11
they can be found on dhe.
- 01:12 - 01:15
All molecules are the smallest units in a chemical reaction
- 01:19 - 01:23
from out of being chemical elements and molecules being smallest
- 01:23 - 01:25
part off a chemical reaction.
- 01:27 - 01:29
So when a group of molecules combine, they create an
- 01:29 - 01:34
organ al, which creates the main activities or works on
- 01:34 - 01:35
the main activities of a cell.
- 01:36 - 01:40
So now what a group of organelles combined, they create
- 01:40 - 01:43
a cell which do the main activities of on organism.
- 01:44 - 01:46
I went on a specified groups of cells.
- 01:47 - 01:48
Combined, they create tissue.
- 01:50 - 01:52
They can create different type of tissues from smooth.
- 01:55 - 01:55
No, those are muscles.
- 01:58 - 02:05
Yeah, they create tissue so from tissue.
- 02:07 - 02:09
When a group of tissues combine, they create organs.
- 02:10 - 02:14
Now organs combined and create a new organ system which
- 02:14 - 02:15
go through the process of life.
- 02:19 - 02:25
Now, when or organ system now in August, um becomes
- 02:25 - 02:26
a kn organism.
- 02:27 - 02:34
Which organism is is a person or animal who goes
- 02:35 - 02:37
through life or go through life functions.
- 02:38 - 02:41
Use this life functions from the organ system to keep
- 02:41 - 02:41
themselves alive.
- 02:43 - 02:50
Simple. So now we're going into second level off organization.
- 02:52 - 02:55
Okay, Now, for the second level of organization.
- 02:57 - 03:01
So, as you can see, we start from organism to
- 03:01 - 03:06
biosphere. Organism has more than one name, or you can
- 03:06 - 03:08
call it from organism or species.
- 03:09 - 03:15
They do have the same meeting still organism or species.
- 03:16 - 03:21
When an organism becomes a population when the organism re
- 03:21 - 03:26
populates, then becomes a group of this similar species and
- 03:27 - 03:32
creates a population now, ah, population becomes ah community.
- 03:34 - 03:40
When the population off this one area meet up with
- 03:40 - 03:47
another population of the same species and the, and when
- 03:47 - 03:49
they combine groups, they keep, they become a community.
- 03:50 - 03:54
So now ah, community becomes an ecosystem when different types
- 03:54 - 04:02
of animals, when different type of animals, go into the
- 04:02 - 04:08
area where a similar type of species looks so like
- 04:08 - 04:14
where money's or rabbits live, Wolf's come and live in
- 04:14 - 04:14
the same area.
- 04:15 - 04:20
Or a flock of birds go, uh, also a similar
- 04:20 - 04:25
area of another fucking birds from a different species, which
- 04:26 - 04:31
means community has become an ecosystem, or an area where
- 04:31 - 04:34
multiple, different type of animals live together.
- 04:35 - 04:39
Now an ecosystem becomes a biosphere when that area is
- 04:40 - 04:44
by its normal self, which with multiple different type of
- 04:44 - 04:48
animals living in that specific area nowhere else in the
- 04:48 - 04:52
world they become a biosphere because there are the only
- 04:52 - 04:55
part of animals that live in that one region off
- 04:55 - 04:55
the world.
- 04:57 - 05:02
So now what the time about themselves and different station
- 05:03 - 05:09
cells Now differentiation cells are on specialized cells, which become
- 05:09 - 05:13
specialized cells, which means that the that the different Dacian
- 05:14 - 05:20
cells become different types of cells, like when specialized cells
- 05:20 - 05:22
can be blood cells, nerve cells.
- 05:23 - 05:26
Sex sells any type of cell come.
- 05:27 - 05:28
But now stem cells.
- 05:28 - 05:30
Stem cells are completely different.
- 05:30 - 05:32
They are not specialized, and they cannot be specialized.
- 05:33 - 05:35
They can create stem cells.
- 05:36 - 05:39
They can create cells, but they cannot be specialized.
- 05:40 - 05:42
There's no limit of how much they can make.
- 05:43 - 05:51
But there is no specialization going on when stem cells
- 05:51 - 05:52
are creating different types of cells.
- 05:53 - 05:57
So now we'll be talking about how stem cells are
- 05:57 - 05:59
using medical fields and research.
- 06:00 - 06:04
Now there are things called stem cells transplants, as when
- 06:05 - 06:10
doctors put stem cells into a different human body, which
- 06:11 - 06:15
means which means that stem cells jobs are to recover
- 06:17 - 06:19
and replace cells that have been destroyed by diseases.
- 06:20 - 06:26
Our illnesses or serve to help the immune system of
- 06:27 - 06:32
people who have cancer or blow related illnesses like leukemia
- 06:34 - 06:36
or other type of blood related diseases.
- 06:38 - 06:42
And most transplants use adult stem cells.
- 06:49 - 06:51
I cannot think of a reason, but they use adult
- 06:52 - 06:52
stem cells.
- 06:53 - 06:59
Now stem cells are researched by doctors or scientists manipulating
- 07:00 - 07:06
the stem cell, which basically means that from a normal
- 07:06 - 07:07
stem cell cannot become specialized.
- 07:08 - 07:13
But when it's modified, stem cells can become any type
- 07:14 - 07:16
of cell needed or what type of cell that doctors
- 07:17 - 07:21
or scientists need when modified.
- 07:24 - 07:28
Okay, this was short.
- 07:28 - 07:30
But I hope you understand.
- 07:32 - 07:36
This video was not that detail, but I hope you
- 07:36 - 07:41
understood. And I hope that, uh, we could get another
- 07:41 - 07:42
one of these assignments.
- 07:43 - 07:43
This was fun.
- 07:45 - 07:46
Thank you for listening.
- 07:46 - 07:49
For hearing me out and listening to me talk.
- 07:50 - 07:51
Have a good day.
