An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answers
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase

which bone layer holds calcium and other minerals
Answers
Answer:
In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

The chart shows information about three different embryos early in their development.
Which is best supported by the information in the chart?
Species X and Y are not related to humans.
Species Y and Z are not related to humans.
Species X and Z are related to humans.
Species X and Y are related to humans.
Answers
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

Answers
Answer:
I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?
