NP plants purple flowers are dominant to white flowers a white flowered plant across with a plant that’s is heterozygous for the
anygoal [31]

Mendel concluded that pea traits like flower color were determined by separate units. From the results, Mendel proved that all traits do not blend. For instance, purple flowers mixed with white flowers did not produce pink flowers.

Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. ... This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.

Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.

Mendel's Results

Mendel noted the ratio of white flowered plants to purple-flowered plants was about 3:1. That is, for every three purple-flowered plants, there was one white flowered plant.

What is the ratio of surface area to volume for a sphere with the following
Leya [2.2K]

Answer:

0.4\ \frac{1}{m}

Explanation:

Let

x ----> the surface area of a sphere

y ---> the volume of a sphere

we know that

The ratio of surface area to volume of a sphere is equal to divide the surface area by the volume of the sphere

\frac{x}{y}

we have

x=588\ m^2\\y=1,372\ m^3

substitute the values

\frac{588}{1,372}=0.4\ \frac{1}{m}

Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photos
Archy [21]

Answer:

rhizobia is an important nitrogen fixing bacteria found in the soil to help grwo plants like legumes. rhizobia enter into a symbiotic relationship withe legumes

Explanation:

rhizobia and legumes coexist by entering into a symbiotic association.  rhizobia is a bacteria that fixes nitrogen molecules for the legumes and in return the legumes provide the bacteria with food and nutrition.

If rhizobia becomes extinct in the near future it would be difficult for plants like legumes to grow as they wouldn't get sufficient nitrogen and nitrogen is an important nutrition for the plant to grow and develop. Thus it can cause rapid depletion or death of plants that need rhizobia to fix nitrogen molecules for them.
