Answer:
A. True
Explanation:
Dr. Edgar F. Codd was able to generate twelve (12) rules after his research on the Relational Database Model. One of his rules, the second one precisely which is the Guaranteed Access Rule specifies that 'all single database elements or values are most certainly guaranteed to be accessible through a combination of the primary-key model also known as the row value, the attribute-name also designated as the column value and the table-name. The information rule which is the first rule also specifies that all information must be represented as one value in rows and columns.
So, this implies that a single database field should contain multiple data values. He also mentioned that data cannot be accessed through any other means except for the above stated.
Name the polar and tropical air masses that affect U.S. weather. Describe the pattern of movement across the continent and patterns of precipitation associated with warm and cold fronts.
Answer:
The answer to this question can be defined as follows:
Explanation:
In the cold surface, the air is defined by polar weather systems and relatively warm surface air masses. Its masses throughout the polar vortex are very cold.
and the 5 air masses, that impact the United States in such a normal year: continental polar, Continental Arctic, continental tropical, marine polar, maritime tropic. It influences the 5 Coastal in the USA for the continental plates, and the pattern of movement can be defined as follows:
influenced both by the West switch to the east from the west SINKS Cold Air Cold, rain and storms, steeper slopeThe sequence of increasing grades of metamorphism of a mudstone (shale, claystone, or siltstone) parent rock (protolith) is: slate (lowest grade), phyllite, schist, gneiss (highest grade).
1. Describe the change in grain size from slate to schist
2. How does the texture of phyllite differ from that of schist?
3. Why do you think that the micas (lat minerals) in these rocks are all parallel, r nearly so, to one another?
The slate is hard and fine-grained rocks and has a salty cleavage that is caused by the growth of minerals due to the metamorphose of the grain ground rocks while schist is medium grade sheet-like grain rock.
The texture of phyllite is very glittery as its a very fine grain size and the grains are flat. Schist has the greatest grain size. Phyllite has a foliated texture but schists consist of scale.Minerals like muscovite and biotite are common rocks forming minerals in micas and are found in the igneous rocks with feldspar and quartz, thus they are parallel and very finely grained flakes in the rock.Hence slate (lowest grade), phyllite, schist, gneiss (highest grade) rocks.

the Black Codes?
How were the Black codes intended to help them
accomplish these goals
Explanation:
Black codes were restrictive laws designed to limit the freedom of African Americans and ensure their availability as a cheap labor force after slavery was abolished during the Civil War. In late 1865, Mississippi and South Carolina enacted the first black codes. Mississippi’s law required blacks to have written evidence of employment for the coming year each January. They left before the end of the contract, they would be forced to forfeit earlier wages and were subject to arrest.

What type of friction do the Nazca and South American plates have?
Answer:
Explanation:
The tectonic plates move among themselves as solid and rigid blocks, moving over the upper level of the mantle (asthenosphere).
When the plates get closer to each other, we say that they converge → ←, when they separate they diverge ← → and if what they do is move laterally next to each other they pass ⇅
In the case at hand, the Nazca oceanic plate converges with the South American continental plate, approaching each other at a rate of about 6 or 8 cm per year. And they have been doing so for at least the last 25 million years.
Since the Nazca plate, due to its composition, is denser than the South American plate, it has less buoyancy and when pushed against it, it folds and sinks towards the mantle where it melts. This process, called subduction, is responsible for the rising of the Andes, as well as the high seismicity and volcanism present along the South American west coast.
Answer:
Andes Mountains.

A landowner who claims title to land deposited slowly by the action of a running stream would base such a claim upon:
Answer:
claim upon accretion
Explanation:
For moment to moment, when a rights of way scheme has been examined, it is found that the actual position of the current natural border of a land being invaded is not in accordance with the position of that border displayed in the map around which the designation is centred.
Where the variance in the position of the natural growing boundaries is due to either accumulation or an wrongly defined environmental boundaries on the map around which the title is centred, a land surveyor may proceed with an application under section 118 of the Land Title Law.

Assuming Singapore's population is constant, what can be inferred about Singapore's home ownership rate from the chart above? A. There were more homeowners in 2009 than in 2000. B. There were more homeowners in 2010 than in 1980. C. There were less homeowners in 2005 than in 2009. D. There were more homeowners in 1980 than in 1990.
Answer:
B. There were more homeowners in 2010 than in 1980
Explanation:
The population of Singapore is 5,703,600 and the homeownership rate has been keep on increasing form 1980 .e 56 % to 87% in 2010. This means that were fewer home buyers earlier and if this rate is held constant then the population rate and housing rates have increased on a large scale. At present, the country is home to 5.7 million residents.Answer:

Explanation:
We live in diverse societies. It is normal for people to disagree about many
things, including religion and politics, but acceptance of the _____ can keep situations from becoming violent.
A. constitution
B. legitimacy of rule
C. legal charter
D. rule of law
Answer: D. rule of law
Explanation:
Socrates once said that humans without rules are nothing but animals. This is an apparent reference to the savagery of the animal kingdom that can see violence occur at the slightest provocation. The Rule of Law refers to the governing principle that everyone is subject to laws that were enacted to ensure that people live together in such a way as not to infringe on the rights of others and thus to prevent societal breakdown.
This is why a general acceptance of it can keep the general peace and keep situations from getting violent. For example, if two people got into an accident and could not agree on who was wrong, if there were no laws on how such an issue would be handled, there would probably be violence between the two. Granted violence might still occur but the incidence rate of this has been greatly reduced thanks to a general agreement to respect the rule of law.
Answer:
D. rule of law keeps situations from becoming violent

Which of the following statements is NOT true:
a) Light moving from a source moving toward the observer will have a higher frequency than if the source were at rest with respect to the observer.
b) The value of Hubble's parameter, H, is determined by measured redshifts of spectral lines for distant galaxies. c) Hubble's parameter, H, is used to estimate both the Universe's size and age.
d) According to Hubble's Law all galaxies must be moving away (receding) from our own.
The question about the finding the true statement based on the space.
Hubble's law is based on the observed physical cosmology and the galaxy that are moving . The speed of earth is proportional to their distance. Thud on their basis the universe is expanding. The expansion is called as Hubble flow.Hubble parameter H is dimension less title. It is a fundamental cosmological property. H, is not used to estimate both the Universe size and age of galaxies.Hence the option C is correct.
