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).

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: 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.

Answer: Temperature: Latitude, Ocean Currents, Altitude

Explanation:

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.

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:

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.

The answer above is false the correct option is Isabel Allende.

Explanation:

I did the quiz and it was correct.

Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In  (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development  are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

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.
