In order to determine the rate of photosynthesis (the conversion by plants of carbon dioxide and water into glucose and oxygen),
Rama09 [41]

Answer:

1.6896 grams

Explanation:

Given that:

Total pressure = The pressure of  O_2 + partial pressure of H_2O

∴

The pressure of  O_2  = Total pressure - partial pressure of H_2O

= (754.8 - 17.55) mmHg

= 737.25 mmHg

At standard conditions:

1 mmHg = 0.00131579 atm

∴

737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm

P ≅ 0.97 atm

The temperature  (T) = 293 K

Volume (V) = 1.31 L

Using ideal gas equation

PV = nRT

0.97 × 1.31 = n × 0.0821 × 293

n = \dfrac{0.97 \times 1.31}{0.0821 \times 293}

n = 0.0528

mass of oxygen  O_2 = no. of moles * molar mass

= 0.0528 * 32

= 1.6896 grams

SVEN [57.7K]

Red-green color blindness is due to a mutant gene in the X chromosome. An XX female with normal color vision and an XY male with normal color vision have a child with karyotype XXY who is color blind. The likely explanation is that the:_--------.

father was heterozygous for the color-blindness mutation.

mother was heterozygous for the color-blind mutation.

father had CNV of the color-blind mutation.

mother had CNV of the color-blind mutation.

None of the other answer options is correct.

Answer:

mother was heterozygous for the color-blind mutation.

Explanation:

Colorblindness is a recessive disorder. This means that it is expressed only in homozygous genotypes. The responsible gene is present on the X chromosomes. A colorblind female would have the genotype X^cX^c where c is the recessive allele of the gene present on the X chromosome responsible for color blindness. A female with genotype X^cX would have normal visible but would serve as a carrier.

Both the female and the male have normal genotype. Since they had a colorblind child, it means that the female was a heterozygous carrier for the trait and imparted the responsible allele to the child. The male can not serve as a carrier for X linked recessive disorder since they have only one copy of the X chromosome. Therefore, the female was a heterozygous carrier.
