Answer:

Option D Codes for a specific trait

Explanation:

The segment of the DNA molecule),the gene, that codes for a particular protein and determines the traits (phenotype) of the individual.( A gene is the basic unit of heredity in a living organism.)

You are interested in studying a gene called CFTR because mutations in this gene in humans cause cystic fibrosis. You have made

ludmilkaskok [199]

Answer:

The mouse CFTR gene and human CFTR gene encode proteins that can serve a similar function.

Explanation:

CFTR (Cystic fibrosis transmembrane conductance regulator) gene that codes for the membrane protein. This gene is responsible for the transport of the chloride ions in the cell.

Any mutation in CFTR gene can cause the lung diseases in individual. As shown in the experiment the mouse gets normal when given normal human CFTR gene. The CFTR gene plays the similar role and function in both huamn and mouse.

Thus, the correct answer is option (C).

For the reaction, Fe₃O₄ + 4 H₂ → 3 Fe + 4 H₂O, what steps do you have to take to determine how many grams of Fe₃O₄ are required

Andreas93 [3]

Answer:

See the steps below (8,681.25 g of $Fe_3O_4$ will be needed0

Explanation:

From the equation, 4 moles of H2 requires 1 mole of Fe3O4.

1st step: calculate the number of mole of 300 g of H2.

mole = mass/molar mass

Mole of 300 g H2 = 300/2 = 150 mole

Hence, 150 moles of H2 will require: 150/4 = 37.5 moles of Fe3O4.

Step 2: Use the mole of Fe3O4 to calculate the mass of Fe3O4

mass = mole x molar mass

mass of 37.5 mole Fe3O4 = 37.5 x 231.5 = 8,681.25 g

Hence, 8,681.25 g of Fe3O4 will be required to completely react with 300 g H2
