When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.

Answers

Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to  use

When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.

Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).

When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.

In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

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.

Answers

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?

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.

Some believe that the lifestyle that money can offer is equivalent to happiness, while others fear that money can lead to greediness that can never be satisfied. In this study, psychologist Daniel Kahneman and economist Angus Deaton seek the answer to this question. As you read, take notes on the different definitions of happiness that exist and how they are affected by money.How much money do you think it would take to make you happy? Would an extra $10,000 a year do it or would it take a $100,000 salary bump to improve your mood?A new study from Princeton economist Angus Deaton and psychologist Daniel Kahneman suggests that number depends on how you define happiness. The authors draw a distinction1 between emotional well-being, the quality of a persons everyday experience such as joy, fascination, anxiety, sadness, anger, and affection and life evaluation a persons thoughts about his or her life (on a longer time scale).Their study of data from the Gallup-Healthways Well-Being Index found that while life evaluations rise steadily with income, emotional well being drops off at about $75,000 a year.Beyond $75,000, money is important for life evaluation, but does nothing for happiness, enjoyment, sadness, or stress. Both factors are important; it is good to have high emotional wellbeing, but it is also good to think your life is going well.According to the most recent census2 data, the median US household income was $52,000 in 2008, with about a third of households making above $75,000.Text-Dependent Questions Directions: For the following questions, choose the best answer or respond in complete sentences.1.
