Answer:
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.[1][2]

The internal structure of Earth
There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field.[3] The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5,700 K (5,430 °C; 9,800 °F), which is about the temperature at the surface of the Sun.[4]

Answer:
Normal Eyes = 75%
Heart eyes = 25%
Explanation:
3 of the offspring in that punnet square have at least 1 dominant allele. And if an offspring has at least 1 dominant allele then it should have the dominant trait( which is normal eyes ). But if it only contains recessive alleles then it would have the recessive trait (which in this case would be heart eyes).
Why can't weeds take over the world? In other words, what limits the growth of populations?
Answer and Explanation:
Many elements can limit population growth. The main elements that can cause this are the lack of resources necessary for the life and development of living beings and the lack of space to be taken by them. In relation to weeds, these resources can be the availability of sun, amount of soil, soil fertility, availability of water and space. However, these plants are very resistant to the lack of these resources, and what most limits their growth is human interference.
Weeds are unfavorable to agriculture and other human activities. This makes humans fight the population growth of these plants using chemical products and even physical strategies. This interference prevents weeds from taking over the world.

Which of the following is true about the coasts of North and South America? O A. Little industry is located along the coasts, B. There are few cities and the population is sparse. O c. A majority of the population is located there. D. People go to the coasts only when on vacation,
Answer:
The correct answer is C. In North and South America, a majority of the population is located on the coasts.
Explanation:
Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.
A 4-base deletion in the AAUAAA sequence in the 3' untranslated region of an mRNA that eliminates the AAU, thereby preventing RNA Polymerase from polyadenylating the mRNA, would have the effect of:
Answer:
decreasing the number of copies of the polypeptide translated from this mRNA
Explanation:
Polyadenylation refers to the addition of multiple adenosine monophosphates (i.e., a polyA tail) to an RNA molecule, usually a messenger RNA (mRNA). Polyadenylation is catalyzed by an RNA polymerase called poly(A) polymerase (PAP), which adds adenine nucleotides to the mRNA. In eukaryotic cells, polyadenylation is required to produce a mature mRNA which is then used as template for protein synthesis during translation. This posttranscriptional modification (polyadenylation) is known to stabilize the mRNA by preventing its degradation by exoribonucleases, i.e., enzymes that degrade RNA molecules by removing terminal nucleotides from 3' and 5' ends. In consequence, it is expected that a mutation that prevents polyadenylation of a target mRNA decrease the number of copies of the protein translated from this mRNA.

What would happen to this nitrogen cycle if a virus killed all the bacteria?
nitrogen would just keep on cycling
plants would take over for the bacteria
the cycle would stop because the plants can't take in atmospheric nitrogen
animals would grow more because there's no bacteria
Answer:
the cycle would stop because the plants can't take in atmospheric nitrogen
Which statement best explains what would most likely occur first in the amount of organic matter in an area suddenly
decreased
A) The amount of atmospheric nitrogen would decrease.
B) The amount of available nitrogen in the soil would decrease
C( The number of nitrogen-fixing bacteria would increase
D( The number of decomposers would increase
Answer:
b
Explanation:
nitrogen will slowly go down due to not having enough organic matter
The statement that best explains would most likely occur first in the amount of organic matter in an area suddenly decreased:
B) The amount of available nitrogen in the soil would decrease.
The statement that best explains would most likely occur first in the amount of organic matter in an area suddenly decreased is the amount of available nitrogen in the soil would decrease. The nitrogen will slowly go down due to not having enough organic matter.Thus, the correct answer is B.

if hypertonic has more solutes than hypotonic does hypertonic have more or less water?
Answer:
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. ... Hypotonic solutions have more water than a cell. Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Introduction of an invasive species to an ecosystem can have some harmful effects including predation of existing species, competition for resources, and overpopulation. These invasive species are introduced primarily by humans when humans travel from foreign countries, when cargo ships bring goods from foreign countries, or when exotic pets are lost or released. Once these invasive species to reproduce, they can take over an entire ecosystem.

Answer:
I think the answer is J: desert.
Explanation:
In the grassland, rainforest, and swamp, it either rains frequently or is constantly surrounded by water. However, deserts rarely get any water. Also, not many desert plants have leaves, but instead have very large stems, like cacti and large sage bushes. Therefore, the desert would be the most important habitat this could take place.
