A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
g100num [7]

Answer:

Explanation:

the purple allele (C) is dominant to the pink allele (c).

The frequency of C represents p while that of c represent q. Using the formula p+q= 1

The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).

Thud to find q which is the frequency of the c allele,

q = √0.153

q = 0.3912

From the formula p +q = 1 we can find p p = 1 - 0.3912

p which is the frequency of the C allele

p = 0.6088.

B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847

What is the
lara31 [8.8K]

Answer:

Current Air Temperature

The current air temperature plotted to the nearest whole degree Fahrenheit.

Dew Point Temperature

The dew point temperature plotted to the nearest whole degree Fahrenheit.

Sky Cover

The total amount of clouds in tenth. Plotted in the station circle according the the following table.

Wind Speed And Direction

The wind direction is plotted as the shaft of an arrow extending from the station circle toward the direction from which the wind is blowing. The wind speed is plotted as feathers and half-feathers representing 10 and 5 knots, on the shaft on the wind direction arrow. See the following table.

Visibility

The visibility plotted in fractions of a mile. For values above 10 miles, the values are omitted from the map.

Sea Level Pressure

The barometric pressure in tenths of millibars reduced to sea level. The initial 9 or 10 and the decimal points are omitted.

ex: plotted = 982, actual = 998.2 mb

ex: plotted = 012, actual = 1001.2 mb

Pressure Tendency

The pressure change in the past 3 hours preceding the observation. Plotted to the nearest tenth of a millibar. The plotted symbol characterizes the change in pressure according to the below chart.

Alexxandr [17]

Answer:

soil and vegetative matter screening for soil structure integrity and invasive pathogens

Explanation:

Repeated use of fertilizer causes the soil to break down and lose it nutrient capacity. This in turn will affect the integrity of the plants, now in a nutrient deficit environment. In addition to this, soil micro-biome environment may also be compromised once soil structure and nutrient is lost. Some of the bacteria, fungi and protozoan in the soil plays a role in defense against invasive pathogens. When this is lost the possibility for infection and increased risk of unknown pest and disease is imminent.
