Which of the following is the best definition of Newton's theory of universal gravitation?
Every object is pulled downward with a force that increases as the height from which an object is dropped increases.
Every object is attracted to the Earth with a force that increases with increasing mass and distance.
Every object attracts every other object in the universe, with a force that increases as the objects' masses decrease and the distance between them increases.
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
the answer would be D!;
every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
The definition of Newton's theory of universal gravitation is : ( D )
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Newton's theory of universal gravitation states that "every object attracts every other object in the universe with an attracting force that is proportional to the product of their masses and is inversely proportional to the square of their distances "
Therefore based on the Newton's theory of universal gravitation the best definition from the options given above is Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Hence we can conclude that Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.

Owls prey on rabbits, mice, and snakes so a decrease in their population would decrease the population of owls.
What is the food chain?
A food chain describes which creature in the ecosystem consumes another. The food chain is a succession of living things that transmit nutrients and energy from one creature to the next. When one organism ingests another, this happens. Following the chain, starts with the producer organism and finishes with the decomposer organism.
The sequence of events in an ecosystem known as a "food chain" occurs when one live organism consumes another organism, which is then eaten by a bigger organism. A food chain is created by the transfer of nutrients and energy from one creature to another at various trophic levels.
The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers at the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain.
Therefore, the owl population would decrease if their prey's population decreased.

Many kinds of data can be gathered in the study of ocean water. Predictions are based on accurate and precise scientific data. Which of these sets of data will yield the most precise data?
Hello. You did not present the answer options, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
The data set that will produce the most accurate data are the most specific and least general data, which have very specific characteristics and circumstances on the ocean water. An example of very specific data is the water temperature, where researchers will be able to interpret accurately and promote accurate data.
Why is drilling oil reserves in the Arctic National Wildlife Refuge (ANWR) controversial? A) The controversy is over removing more nonrenewable resources from an area that has been set aside for the ecological health of wildlife. B) The controversy is about how much oil is actually in the ANWR. C) The controversy is over the cost of drilling for and extracting oil, and whether the government will subsidize the oil industry. D) The controversy is among people who want to store nuclear waste in the area, oil companies that want to extract oil, and indigenous people who want to keep their hunting territories. E) There is no controversy about this area because it has already been preserved for wildlife.
Answer: A

Recombinant DNA technology involves which sequence of steps?
Answer:
B
Explanation:
Processes of recombinant DNA technology involve isolation of DNA of the desired DNA fragment. In order to cut the DNA with restriction enzymes, it needs to be in pure form, free from other macromolecules. The DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides, and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). The RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease.

Which body system transports the hormones that control the menstrual cycle?
Answer:
The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum. Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg. If a pregnancy occurs, the corpus luteum produces progesterone until about 10 weeks gestation.
The diagram below represents an energy pyramid constructed from data collected from an
aquatic ecosystem. Which statement best describes this ecosystem?
A.The ecosystem is most likely unstable.
B.The herbivore populations will continue to increase in size for many years.
C.Long-term stability of this ecosystem will continue.
D.The producer organisms outnumber the consumer organisms.
Energy pyramids are the models that show the flow of energy from the primary to the next level. From the energy pyramid, it can be said that long-term stability will be continued. Thus, option C is correct.
What are energy pyramids?Energy pyramids are the representation of the energy levels and the primary producers and other consumers. The producers are the base of the pyramid followed by the primary consumers.
In an aquatic ecosystem, the algae are the primary producers that provide energy to plankton and act as primary consumers. These are get eaten by small fishes and large fishes. The number of consumers gets decreased as one rises to the upper level.
Therefore, option C. an aquatic ecosystem will have stability.

EDTA is commonly used in foods and cleaning products. It is also used in police laboratories to prevent the degradation of samples. Explain two ways this might serve as a problem in a trial involving DNA evidence.
Answer:
EDTA is a chelating agent used to preserve samples for DNA extraction and as an anticoagulant
Explanation:
Ethylenediaminetetraacetic acid (EDTA) is a well-known chelating agent that binds metal ions (iron and calcium ions). In police cases, EDTA can be used for DNA extraction since this agent chelates metal ions in DNase enzymes which are contained in the samples, thereby reducing their activity and preserving DNA samples for a long time. Moreover, EDTA is also used as an anticoagulant for blood cells, which allows preserving the cellular components and the morphology of blood samples.

"Using forests wisely"
"Community conservation"
Answer:
Social issues such as poverty and to fulfill basic needs etc.
Explanation:
Social issues such as poverty, lack of awareness and to fulfill basic needs etc affected the problem or its solution in the stories i.e. "Using forests wisely" and "Community conservation" because these issues forced people to cut the forest and use the lands unwisely to fulfill their basic needs and betters their social status in the society. Due to poverty, people cut the trees in the forest and sold them to earn money in order to buy food and other necessary items for their family. If these social issues are solved, there is no need for cutting of trees and land use.

What is DNA?DNA stands for deoxyribonucleic acid.
DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.
It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.
There are basically two types of DNA.
Autosomal DNAMitochondrial DNAToday, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.
