Can you create a punnett square for this question?

Biology
1 answer:
Ierofanga [76]3 years ago
3 0

Answer:

The correct answer is 50%.

Explanation:

In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:

Punnett square:

      R       R'

R'    RR'   R'R'

R'    RR'   R'R'

It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%

6. (3 pts) After transformation, 40 colonies were present on the plate. What is the transformation efficiency of the competent c
natali 33 [55]

Answer:

Given:

Number of colonies on plate = 40

Amount of DNA used for transformation = 100ng

Volume of competent cells used = 100ul

Total volume = 1ml (1000ul)

Volume plated for growth = 200ul

The amount of cells transformed per 1 µg of DNA is called the transformation efficiency

(CFU is colony forming units) => (number of colonies on plate/ng of DNA plated) X 1000 ng/µg = CFU/µg of DNA

Amount of DNA used for plating = 100ng * (200/1000)

                                                      = 100ng * (1/5)

                                                      = 100/5 = 20ng

Efficiency calculation = 40 colonies / 20ng = 2 colonies/ng

               (2 colonies/ng) * (1000 ng/µg) = 2000 CFU/ug DNA

Transformation efficiency = 2000 Transformants / ug DNA

                                          = 2 x 10³ Transformants / ug DNA

Explanation:

Efficiency of transformation is highest in the 100 pg-1 ng range, so Low transformation efficiency could be because of high amount of DNA used for transformation.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.
