The relationship between population growth and technological change has been debated since the end of the eighteenth century a debate whose main configuration has proved remarkably persistent. During the ensuing 200 years, historically unprecedented rates of change have been observed in both variables: in industrial, commercial, and communications revolutions spreading out from Europe, North America, and Japan; in parallel (though spatially and temporally uneven) revolutions in the technological base of agricultural production; and in a demographic transition–in which mortality decreased and fertility first increased, then decreased that is still underway in many developing countries. Interconnections there must be, yet the attribution of primacy and direction of causation among these variables, not to mention the nature of the mechanisms involved and means of influencing outcomes in the interest of meeting social goals, remain controversial. Meanwhile, a new awareness of the emergence of complex social-environmental systems, whether at local or global levels, has extended the debate beyond the discipline of economics, and broadened its emphasis from the welfare of the human race to that of the planet.
What is cellular respiration?
Answer:
cellular respiration is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it
The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.
We can arrive at this answer because:
When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.

and you start running in a positive direction into a tumbling pass, starting from rest.
At 2s, your velocity is 4.5m/s. Calculate your acceleration.
Your Answer:
Answer
units
Answer:
2.25 m/s^2
Explanation:
Acceleration is the speed which you are increasing by per second. Therefore to find acceleration all you need to do is divide the change in velocity (4.5) by the time (2). Your units than become (m/s)/s or m/s^2.

Causal attribution theories generally try to explain how we:
1) are influenced by others
2) predict how others will behave based on their attitudes
3) change our attitudes toward other people
4) determine the causes of others' behavior
5) relate to and interact with other people
Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.
This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.
Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.
Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.

explain why antibiotics are not consistently effective against infection of bacteria
Explanation:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

list five traportance of science to men
1. Science is the greatest collective endeavor. It contributes to ensuring a longer and healthier life, monitors our health, provides medicine to cure our diseases, alleviates aches and pains, helps us to provide water for our basic needs – including our food, provides energy and makes life more fun, including sports, music, entertainment and the latest communication technology. Last but not least, it nourishes our spirit.
2. Science generates solutions for everyday life and helps us to answer the great mysteries of the universe. In other words, science is one of the most important channels of knowledge. It has a specific role, as well as a variety of functions for the benefit of our society: creating new knowledge, improving education, and increasing the quality of our lives.
3. Science must respond to societal needs and global challenges. Public understanding and engagement with science, and citizen participation including through the popularization of science are essential to equip citizens to make informed personal and professional choices. Governments need to make decisions based on quality scientific information on issues such as health and agriculture, and parliaments need to legislate on societal issues which necessitate the latest scientific knowledge. National governments need to understand the science behind major global challenges such as climate change, ocean health, biodiversity loss and freshwater security.
4. To face sustainable development challenges, governments and citizens alike must understand the language of science and must become scientifically literate. On the other hand, scientists must understand the problems policy-makers face and endeavor to make the results of their research relevant and comprehensible to society.
5. Challenges today cut across the traditional boundaries of disciplines and stretch across the lifecycle of innovation -- from research to knowledge development and its application. Science, technology and innovation must drive our pursuit of more equitable and sustainable development.

How does the anatomy of mitochondria allow it to do
cellular respiration?
Answer: Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients.
What would happen to the DNA molecule if the pairing was non-complementary, in other words, the two purines (adenine and guanine) paired with one another and likewise the two pyrimidines (thymine and cytosine) paired with each other.
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.
