The arc length of a circle can calculated by the equation:
Arc length = 2πr(C / 360)
where r is the radius and C is the central angle.
Therefore, the arc length of this circle should be calculated as follows:
<span>Arc length = 2π(8)(95 / 360)
</span>Arc length = 13.26 in
When did frogs evolve? Frogs developed out of lungfish about 375 million years ago, in the Devonian period. They used their lungs to leave the water and live on land
Answer:
2:random
Explanation:
Mutations are RANDOMLY caused by mistakes in the DNA replication process there is no telling when they will happen, nor is there a way to force mutations!

Answer:
d. none of the above.
Explanation:
The growth hormone from the pituitary gland targets soft and hard tissues. It is responsible for growth during the growing years. Hypersecretion of growth hormone in adults causes acromegaly. Closure of epiphyseal plates in long bones occurs after the growing age. Therefore, long bone growth is not possible in response to growth hormone in adults. But bones of the feet, hands, and face become overly large in these organisms.
I think the correct answer would be the third option. Organisms that help break down dead organic material so it can be recycled into a usable form for other organisms are called decomposers and this would include some of the bacteria. Also, there is a number of bacteria that are capable of breaking down some of the harmful products like in recent studies there are bacteria that could dechlorinate the toxic PCB substance. Some bacteria, as well, lives in the human intestines which aids in the breaking down of the food into useful molecules. The third option is partially true since there are some bacteria like the cyanobacteria which produces oxygen but it does not contribute largely to the oxygen present in the atmosphere.
