Answer:
Asteroids or planetoids are small solids in planetary systems. They usually orbit the parent star in their own orbit or as natural satellites (moons) of larger planets.
A comet is a celestial body that is in an elliptical orbit around the Sun. They come from the farthest and coldest areas of the solar system.
Explanation:
The moon is the only natural satellite of the Earth and at the same time the closest celestial body.
It is the brightest celestial body in the night sky, not because it consists of incandescent gases like the sun, but because it reflects sunlight.
A planet is a celestial body that moves directly in an elliptical orbit around a star, not like a natural satellite, which orbits a star while circling around another body.

"Image result for why cells can form tumors
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor."

A scientist is studying a species of mouse living in a field. She observes that the mouse nests are mostly made from cogongrass, a type of grass that is common in the field. After doing some research, she creates the hypothesis that the mice make their nests out of materials that are easy to find.
What would be the scientist's next step in gaining knowledge about how the mice choose their nesting materials?
A.
coming up with more questions about the mice
B.
creating other possible hypotheses about the nests
C.
performing an experiment to test her hypothesis
D.
publishing her hypothesis in a scientific journal
Answer:
B
Explanation:
Creating other possible hypotheses about the nests.
What is Nesting material?
Everything birds may use to build a nest is referred to as "nesting material."
All birds require suitable materials for their nests, regardless of whether they build a straightforward depression out of wood and straw or a more complex nest structure with complicated construction.
Depending on the size of the nest, where it is built, and how it will be utilized in terms of the number of eggs, several broods, and yearly reuse, different birds will use different materials to build their nests.
Several birds gravitate toward fluffy material, such as seeds with silky attachments designed to blow them on the wind or seed pods with a soft, hair-like covering.
Therefore, Creating other possible hypotheses about the nests.

I do not think it is possible because plants do photo synthesis in a organelle called chloroplast which humans do not have.
X-rays carry a small risk of damaging DNA which can lead to cancer. Why are they still used by doctors?
Answer:
Despite the risk of DNA damage and cancer production, X-rays are still used by doctors because the benefit of this diagnostic study outweighs the risk, which in most cases is very low.
Explanation:
Diagnostic radiology studies, such as X-rays and CT scans, are procedures that use ionizing radiation to obtain images of the inside of the body. Prolonged or constant exposure to this type of radiation is harmful because there is a risk of producing damage to DNA and can lead to the development of cancer.
However, the use of X-rays and CT scans are non-invasive diagnostic methods whose information provides an accurate diagnosis of a disease and, when well used, has a very low risk of organ damage.
Ionizing radiation is measured in milisieverts (mSv) and exposure from radiologic studies is in the range of 0.1 to 10 mSv per study. The amount of ionizing radiation a person is expected to receive per year from exposure to their environment is in the order of 3 to 5 mSv per year, so diagnostic imaging studies involve a low risk of organ damage.
Doctors continue to use X-rays as a diagnostic study, despite the risk of cancer and DNA damage, because the benefit —accessible, noninvasive, and cost-effective— far outweighs the risk.
In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

Our Sun has a surface temperature of about 9000 degrees Celsius, and is G2 Star.
Answer:
Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class of surface temperature about 5,800 kelvins (K) and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.
Answer:
According to NASA, the sun's temperature ranges from roughly 27 million degrees Fahrenheit (15 million degrees Celsius) in its core to just around 10,000 degrees Fahrenheit (5,500 degrees Celsius) at its surface.
The Sun is classed as a G2 V star, with G2 denoting the second hottest stars in the yellow G class—surface temperatures of roughly 5,800 kelvins (K)—and the V denoting a main sequence, or dwarf, star, which is the most common star in this temperature range.
Which of the following is NOT a type of single gene genetic disorders?
Common medical problems such as heart disease, type 2 diabetes, and obesity do not have a single genetic cause—they are likely associated with the effects of multiple genes (polygenic) in combination with lifestyle and environmental factors.
The Lubber grasshopper is a very large grasshopper, and is black in color with stripes. The color of the stripes exhibit incomplete dominance. Red stripes or yellow stripes may be expressed; however, when alleles are mixed, orange stripes are expressed. What will be the genotypic and phenotypic ratios be for the offspring of two parents that both have orange stripes.
Genotype: ______________________________
Phenotype: _____________________________
Explanation:
Let R be the allele for red stripes.
Let r be the allele for yellow stripes.
Parental phenotypes:
Orange stripes * Orange stripes
Parental genotypes:
Rr * Rr
Gametes:
(R)(r) * (R)(r)
Using a Punnett's Square, we get
F1 generation genotypes:
RR : Rr : rr = 1 : 2 : 1
F1 generation phenotypes:
Red : Orange : Yellow = 1 : 2 : 1.

The process in which RNA are formed from DNA is called as Transcription where as the process in which Protein synthesis occur from RNA is called as translation.
Transcription occurs in the nucleus where as Translation occurs in the cytoplasm.
In Initiation phase of transcription RNA dependent polymerase bind to DNA promoters.
The initiation phase of translation involves association of ribosome subunits, tRNA, and initiation factor to mRNA.
Termination step of of transcription includes the release of RNA transcript or mRNA
In translation the ribosome meets stop codons which leads to the dissociation of the ribosome from polypeptide chain. Thus option A is correct.
