Mainly Osteoarthritis (OA) happens when the joint-associated problems that can occur as normal changes to the articular cartilage as an individual ages.

It is a classic age-related disorder. It is often described as a chronic degenerative disease and thought by many to be an inevitable consequence of growing old. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone. In OA, degradation and loss of the articular cartilage is a central feature that is sometimes attributed to "wear and tear".

Beside Osteoarthritis, fibrillation of the articular surface, decrease in the size and aggregation of proteoglycan aggrecans, increased collagen cross-linking and loss of tensile strength and stiffness happens.

What does 7263×27 equal

dezoksy [38]

Since it is easily calculated using a calculator, I assume you need this done in the head.

Yes, you can do that.

It takes a few words to explain this, but if you understand how this is done, it goes fast.

27=3*9

so 7263*27 = (7263 * 3) * 9

so first multiply 7263 by 3.

72*3=216, 63*3=189

so 3*7263=21789

So far so good.

Now you can multiply anything by nine by subtracting from the right neighbour, starting from the right.

For example, 27*9. the right neighbour of 7 is 0, borrow 1, so 10-7=3

the right neighbour of 2 is 7, but we borrowed 1, so 6. 6-2=4

At the beginning of the number 27, we add a zero which we subtract from the right neighbour 2 to get 2.

So 27*9=243.

Now for 21789, we have successively

(10)-9=1

8-8=0 (9 was borrowed to become 8)

8-7=1

7-1=6

(11)-2=9

and finally

1 -0 = 1 (2 was borrowed to become 1)

So the final answer is 196101

Place the following cell types in the order they are shown to appeared on earth

notka56 [123]

Answer:

1. Prokaryotic (about 3.5 to 3.8 billion years ago)

2. Photosynthetic (about 3.4 billion years ago)

3. Eukaryotic (about 2.7 billion years ago)

4. Aerobic (about 2.5 billion years ago)

5. Anaerobic (about 2.4 billion years ago)

6. Multicellular (about 600 million years ago)

Explanation:

I am not completely sure but my research indicates the following in chronological order from the oldest to the newest:

1. Prokaryotic (about 3.5 to 3.8 billion years ago)

2. Photosynthetic (about 3.4 billion years ago)

3. Eukaryotic (about 2.7 billion years ago)

4. Aerobic (about 2.5 billion years ago)

5. Anaerobic (about 2.4 billion years ago)

6. Multicellular (about 600 million years ago)

<em>Disclaimer: My answer may be incorrect because I am not completely sure but I think this is right</em><em>.</em>

If you are fine with it, I would appreciate if I got the brainliest answer :)

Assume this is an acceleration graph, where the X axis represents time in seconds and the Y axis represent velocity in m/s.

Sindrei [870]

The acceleration is the greatest in the interval 10m/s to 1.5m/s

Explanation:

From the given time it is evident that as the time goes the acceleration decreases which is called deceleration. The formula used to find the high deceleration interval is

a= $\frac{v-u}{t'-t}$

Hence, the answer you would get is -16 $m/s^{2}$ , where negative sign stands to show that it is a decreasing acceleration.
