how do non genetic traits get passed on to offspring

Answer:

B

Explanation:

Female birds mate with the males who build the best nest is the example of option b. sexual selection.

Sexual selection is a mode of natural selection in which one sex members choose the mate with the member of the other sex for mating.

Thus, the correct answer is option b. sexual selection as female birds prefers species-specific traits to select their mating partner by best nest building by males.

The sugar used as the baseline for the sweetness scale is sucrose.

The sweetness scale is a comparative analysis of sweeteners, as well as a means of measuring sweetness. Sugars, sweeteners, and sugar substitutes are rated on the sweetness scale. The sweetness of sugar, which is sucrose, is used as a baseline against which all other sweeteners are compared. The sweetness scale is a useful instrument for consumers as well as food and beverage manufacturers.

Sucrose, which is table sugar, is used as the baseline for the sweetness scale. It is assigned a sweetness value of 100. Other sugars and sweeteners are assigned sweetness values relative to this number. For example, glucose syrup has a sweetness value of 75, while fructose has a sweetness value of 173. The sweetness scale is a convenient method to compare the sweetness of various sugars and sweeteners.

In conclusion, Sucrose is the sugar used baseline in sweetness scale.

uremia

Uremia. Toxic condition resulting from renal failure in which kidney function is compromised and urea is retained in the blood.

The percentage of carbon-14 in human hair from a grave in Africa can be used to estimate the age of the body. Carbon-14 is an isotope of carbon that is present in living organisms. It undergoes radioactive decay over time, with a half-life of 5730 years.

In this case, the human hair from the grave had only 58% of the carbon-14 compared to living tissue. To determine when the body was buried, we can use the concept of half-life.

Since the half-life of carbon-14 is 5730 years, we can calculate the number of half-lives that have occurred by taking the logarithm of the remaining carbon-14 percentage. Using the formula:

Number of half-lives = (log(percentage remaining) / log(0.5))

In this case, the percentage remaining is 58%. Plugging this value into the formula, we get:

Number of half-lives = (log(58) / log(0.5))

Calculating this gives us the number of half-lives that have occurred since the burial.

Once we have the number of half-lives, we can multiply it by the half-life of carbon-14 to determine the age of the body. For example, if we find that 2 half-lives have occurred, we would multiply 2 by 5730 years to get the age of the body.

It is important to note that this method provides an estimate and may not be exact. Additionally, other factors such as contamination or natural variations in carbon-14 levels can affect the accuracy of the result.

Therefore, it is recommended to use multiple dating methods and consider other evidence to obtain a more accurate estimate of the burial age.

Answer:

Carl Linnaeus

Explanation:

He's considered to be the father of taxonomy.

The "base-pairing" rules of DNA were first proposed by James Watson and Francis Crick in 1953.

The "base-pairing" rules, which describe how the four nitrogenous bases in DNA pair up with each other (A with T, and C with G), were first proposed by James Watson and Francis Crick in their seminal paper published in the scientific journal Nature in 1953.

However, it is important to note that the idea of base-pairing had been suggested earlier by several other scientists, including Erwin Chargaff, who discovered that the amounts of A, T, G, and C in DNA varied between species, and that A always paired with T and G always paired with C in equal amounts. Rosalind Franklin, who produced critical X-ray diffraction images of DNA, also played an important role in elucidating the structure of DNA and contributed to the understanding of base-pairing.

Answer:

Something known as magma chambers.

Explanation:

A magma chamber is a big blob of melted, liquid rock within the Continental Crust.

The rock under our feet (Continental Crust) is basically solid. At subduction zones, in particular, friction (or other) heat can melt the rock at the base of the Continental Crust, and then blobs of molten rock melt their way upwards into the Continental Crust. That’s a magma chamber.

Sometimes the magma chamber has vents leading up to the open air and the magma erupts as volcanoes. In that case, the magma chamber can empty out and the ground above collapses into it, making a hole called a caldera. But more often, the magma in the magma chamber cools down to form solid rock. Such slow-cooled rock will form crystals as it cools. One form of such crystalline rock is granite; cooled down former magma chambers now solid granite are called plutons or batholiths. Typically they will be several kilometres across, and later erosion may well expose them at the surface.

Pacinian corpuscles are rapidly-adapting, deep receptors that respond to deep pressure and high-frequency vibration.

Meissner corpuscles consist of a cutaneous nerve ending responsible for transmitting the sensations of fine, discriminative touch and vibration. Meissner corpuscles are most sensitive to low-frequency vibrations between 10 to 50 Hertz and can respond to skin indentations of less than 10 micrometers.

It is to the aggregation of the red corpuscles that the blood owes its red hue, although when examined by transmitted light their color appears to be only a faint reddish yellow. The corpuscles vary slightly in size even in the same drop of blood, but the average diameter is about 7.5μ,  and the thickness about 2μ.

The benefit of crossing over is that during crossing over there is an exchange of genetic material between the chromosomes.  So option A is correct.

Crossing over produces new gametes with new sets of genes. This helps to increase the genetic variety of any progeny. Crossing over is important because it guarantees genetic diversity and promotes genetic reassortment, which is the primary determinant of genetic diversity among offspring that would otherwise result in a high incidence of abnormalities and genetic disorders.

In the event of unequal crossing over, the event results in the deletion of one of the chromatids involved and the insertion of another, which can result in genetic disease or even developmental failure if a critical gene is lost.
