Which structure within a bone contains cartilage cells that divide and increase the size of the bone until adult hood?

1 answer:

6 0

The growth plate is the structure within a bone that contains cartilage cells that divide and increase the size of the bone until adult hood.

To add, the growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the end of the long bones in children and adolescents.

Answer: hopefully this helps? :)

Explanation:The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them. Figure 7. Hydrogen bonds form between complementary nitrogenous bases on the interior of DNA

Use the normal ecg trace below to determine how many seconds the trace represents as well as the heart rate.

mezya [45]

Attached is the image of the concerned ECG reading.

In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.

<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>

Not always. It just depends on if the traits stay the same

Experimentation is a scientific process wherein you test and verify a hypothesis based on its assumption is going to be supported or negated (null hypothesis). Hence experimentation involves the independent and dependent variable, also control variable as a level in the IV. </span>

What index provides evidence of when different types of life evolved on Earth?

aev [14]

There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.

There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.

Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.

These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
