Answer:
0.146 g
Explanation:
Given data:
Volume of solution = 100 mL
Molarity = 10 mM
Molecular formula = C₇NH₁₆O₂
Mass of C₇NH₁₆O₂ needed = ?
Solution:
First of all we will convert the mM into M and mL to litter.
Volume of solution = 100 mL
Volume of solution = 100 / 1000 = 0. 1 L
Molarity = 10 mM
Molarity = 10 / 1000 = 0.01 M
Molar mass of C₇NH₁₆O₂ = 146.21 g/mol
For 1M solution we dissolve 146.21 g/mol in one litter
For 0.01 M
146.21 g/mol × 0.01 mol/ L = 1.4624 g/L
while we have to make 0.1 L solution,
1.4624 g/L ×0.1 L = 0.146 g

Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
- Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.
- Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.
- The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.

Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>
