First of all, you must understand that the average life span of a person is from 70 yrs. throughout the world. See (Picture 1). Life expectancy is measured by the average of each individual who have lived inside a nation or area. It then takes into account how long they live. Was there a ongoing war affecting that area? Was there pestilence, famine, or any natural disasters? These are some examples that would affect the population of a certain demographic, and can lead to people living longer or shorter, which in turn can fluctuate the total amount in the world population. In the case of a longevity of the race of humanity, there are many things to look at.
Firstly, the ever expanding usage of the ground to furbish the energy needed for the sustainability of life. One of the many necessities that a person must meet is having access to a stable source of food, as well as water. The first part comes in the form of gathering, or finding edible food while staying away from those that are harmful. This typically came in a trial-and-error format, and gave those who survived a broader knowledge of what can be eaten, and what cannot be. The second part is the advancement of tools such as spears using flint rock, or forging of sharp wooden staves that can be used to hunt game or fish. Furbishing of meat into the diet led to people generally having more muscle strength, as well as as well as retaining muscle mass, building stronger bones and absorbing iron much more better, which is essential in blood production. Whenever there is a large and stable source of food, as well as later having a globalization trading effort, the world population would grow. Stability almost always lead to higher population growth.
Secondly, the practition of medicine and advancement in the medical field. Medicine plays an important role in not only stabilizing the homeostasis of the body, but also to prescribe a positive role in preparing the human body to develop anti-bodies to counter any new diseases (to the individual) by giving doses of weakened traits. The usage of medicine and other ways in keeping a person healthy (such as sewage systems to drain away wastes full of germs), and the advancement of medicine to negate new diseases have allowed people to survive any incidents and live longer.
Thirdly, the stability of the world (as in wars). Having smaller wars, or little to no war can affect the stability of an economic, political, and social climate of a country. The more balanced and secure it is, the more a group is willing to have children in most cases. However, that is not too say that this means that the growth rate is increasing. Stability also brings, as studies would typically show, a typical mindset for people to make more money in their early adulthood in which case to save for the future. This means putting aside finding a family, or even having kids. Marrying later typically means that the usual ages of childbearing and rearing are on it's waning stages or have already passed, in which it means that the growth is slacking. However, remember the point that I brought up that people are living longer now. This means that the world population is expanding, but not because of new population, but because of the longevity of the old. (See Graph 2).
Finally, you must understand that growth rate as a whole is not as low as expected. The growth rate can be different from country to country. Countries that typically lean towards 2nd or 3rd world countries typically still have a larger growth rate. These generally account for the large amount of world population, even though as a general rule the growth rate is decreasing in most developed countries. Take a look at the graphs shown below (picture 3 & 4). The 3rd one shows the GDP as comparable to each individual countries, which in turn typically means if the country falls under which world category.
In the end, the World Population is made up of many different individual countries, in which each experience it's own growths or set backs in population sizes. One must also take into account the movement of people through countries (typically from developing to developed) in sustaining of other places. Also, one must take into account that not only stability, but also necessity would influence a persons decision to have children, which in turn would affect the growth rate. Advancement in providing the basic necessities and health services to a person would raise the longevity, which means that while not only the population is increasing, but that the population is leaning more towards the older side then younger. Finally, the world population has a peak in limit, and that once the limit is hit, the growth rate and roof would cave the population and lower it down, typically through diseases, famine, or other natural disasters.

OGCTAATCGAT to CGAUUAGCUA
CATCTATGAG to GTUGUTUCTC
No
Answer:
CTGACTGACC to GACUGACUGG
AGCTCCGATC to UCGAGGCUAG
GCTAATCGAT to CGAUUAGCUA
Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light
Are the Earth's seasons caused by the differences in the distance
from the Sun throughout the year or the tilt of the Earth's axis?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Answer:
its A/F
Explanation:
A sample of human DNA is made up of approximately 30% adenine. The quantity of cytosine found in human DNA will be 20%. The correct option is B.
What is DNA base pairing?DNA base pairing is the pairing or joining of DNA bases to each other with hydrogen bonds. There are four types of bases present in DNA. They are adenine, thymine, cytosine, and guanine.
Adenine pairs with thymine with double hydrogen bonds and cytosine joined with guanine with triple bonds of hydrogen. The pairing between these base pairs is alternated in the sequence of DNA.
According to the base pairing rule. There will be 100% of these bases present together. So if there is 30% adenine, there will be 30% thymine. The total becomes 60%. Now remain is 40%. So there will be 20 % cytosine and 20% guanine.
Thus, the correct option is B 20%.

A. The sun heats the air at the equator, followed by hot air rising and moisture condensing
B. Air moves towards the poles as it cools
C. The dry air moves back to the equator, picking up a lot of moisture on the way
D. The air sinks around 30° latitude and is very dry.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".
Why is the line graph a curve instead of a straight line?
Answer:If it's important to display the exact values, then the straight lines do a much better job. But often you'll find that what matters is the trend and the precise measurements are secondary. ... A straight line suggests that the value between the two measurements increased linearly, while a curved line suggests otherwise.

Explanation:
1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.

PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.
