Answer:(Mendel's Second Law of Inheritance) Independent Assortment
Explanation:
Mendel is one of the fathers of genetics science and here are four law and postulates in the sphere of inheritance he shared: • Principle of Dominance • Principles of Paired Factors
• (Mendel's First Law of Inheritance) Law of Segregation or Law of Purity of Gametes and • (Mendel's Second Law of Inheritance) Law of Independent Assortment
Answer:
15.625 g of a 500 gram sample of potassium-42 with 12.4 hours of Half -life is left after 62 hours.
The half-life is the time after which half of the initial quantity of a radioactive substance is left .
Given here,
The half-life of K-42 = 12.4 hours
The initial quantity of K-42 = 500 gm
The final quantity after 62 hours = ?
The number of half cycle
\bold { = 62\times \dfrac 1{12.4} = 5,}=62×
12.4
1
=5,
Thus the number of half life cycles in 62 hours is 5,
After 1 half life \bold {= \dfrac {500}{2} = 250}=
2
500
=250
After 2 half lives \bold {= \dfrac {250}{2} = 125}=
2
250
=125
After 3 half lives \bold {= \dfrac {125}{2} = 62.5}=
2
125
=62.5
After 4 half lives \begin{gathered}\bold {= \dfrac {62.5}{2} = 31.25}\\\end{gathered}
=
2
62.5
=31.25
After 5 half lives \begin{gathered}\bold {= \dfrac {31.25}{2} = 12.625}\\\end{gathered}
=
2
31.25
=12.625
15.625 g of a 500 gram sample of potassium-42 with 12.4 hours of Half -life is left after 62 hours.

ANSWER IS THAT CRRECT
Answer:
The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops. The word filament is from the Latin word filum, which means "thread." Filament, in fact, can be a synonym for thread.
Answer:
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure.It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes
