Answer:
They consist mainly of iron-nickel metal with small amounts of sulphide and carbide minerals. During the decay of radioactive elements in the early history of the solar system, many asteroids melted and the iron they contained, being dense, sank to the centre to form a metallic core.

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.

What is true of all body cells except sex cells?
While each cell type in the body contains the same kinds of genes, they are organized on a different number of chromosomes depending on the cell type.
Each body cell contains the same number and kinds of chromosomes for that organism. In humans, the same 46 chromosomes are in every body cell.
Each body cell type carries a different number of chromosomes that code for that type of cell.
While each cell in the body contains the same number of chromosomes, each cell type has a different number of genes along those chromosomes.
Answer:
While each cell in the body contains the same number of chromosomes, each cell type has a different number of genes along those chromosomes.

In which of the following situations do you think current will flow
please help me answer this question
Answer:
Source of current, force and pathway.
Explanation:
Source of current, force and pathway are the three important things needed or responsible for the current flow. A supply of electric charges (electrons) which is provided by the electric source, force of push to move the charges through the circuit and a pathway on which current flows. Without these three things, flow of current is impossible. so we can say that the situation in which all these three things are present will allow the current to flow in the circuit.

If two organisms have similar traits of DNA they probably
Answer:
4th Option, share a common ancestor.
Explanation:
If two organisms have similar traits of DNA they probably share a common ancestor is the most suitable option to fill the blank.
When the two organisms have similar traits of DNA they probably share a common ancestor.
Two organism have the same traits:When the genes are shared so it preserved the ancestor record where they share with each other and excludes the bacteria.
And, if the DNA is the same for two organism so they would share the a common ancestor.
hence, the last option is correct.

Hard water can cause your dark clothes to fade faster than they should. ... Explanation:
You get those stains for the same reason you get similar-looking stains inside porcelain sinks and toilets – iron in the water. Household water containing a lot of iron may leave those stains on your clothes.
What is duplication event ?
Answer:
Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes.

Please help on #21 I’ll mark you as brainliest if correct
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.

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

the cycle would stop because the plants can't take in atmospheric nitrogen
Soil erosion is a huge problem affecting human sustainability because soil is so crucial in
growing food. True or false ?
Healthy top soil is needed to grow crops, which in turn some of it becomes food. Erosion is the process in which top soil is carried away by the wind or rain water (depositing it into nearby lakes or streams). Without this top soil, farming becomes more difficult and crop yields likely decrease. In some cases, no crops can be grown at all. An extreme example of soil erosion, specifically wind-driven soil erosion, is the 1930s dust bowl during the Great Depression. This occurred due to over-farming and it led to massive dust storms. In turn, it caused many farmers to leave the area.

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.
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.

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.

Scientists have determined that Earth's interior has layers with different properties. One property is that the inner core is solid. Which of the following statements can be used as evidence to support this property?
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]
