Answer: Rift Valleys

Explanation:

A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.

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 genetic information carried by DNA is transcribed into a code that is carried by RNA, which is translated into a specific protein that determines a phenotype. Thus option A is correct.  

The central dogma of life consist of replication, transcription, translation and reverse transcription.

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.

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.

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).

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.

Answer:

the second choice is correct

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.

Answer:

B. algae

Explanation:

biotic factor means something alive is in the factor. all the others are abiotic factors

The biotic factor is a living factor providing a source for ecosystem development, hence option b algae in the water are the correct option.

A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.

A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.

Turbulence, temperature, water clarity, habitat size, and water depth all influence the structure and function of ponds and lakes. Temperature interacts to affect lake stratification and water circulation.

Therefore algae that balance the aquatic ecosystem is a major abiotic factor, hence option b  in water-growing algae is correct.

Creating other possible hypotheses about the nests.

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.

Explanation:

I did the quiz and it was correct.

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.
