Heredity is the study of how traits are passed from parents to offsprings through reproduction. Off springs cells acquire the genetic information from their parents. DNA bases (A,G,C,T) determine the nucleotides that will constitute the mRNA, the mRNA nucleotides determines the codons which codes for certain amino acids. The amino acids join during translation and form peptides that then join to form proteins. These proteins include enzymes that catalyses chemical reactions for example pigments of skin and hair color are produced by enzymes. Hence, proteins highly determine the traits acquired by a given organisms and therefore, variation in a gene in terms of the bases greatly affect the proteins formed hence influencing the traits of the organisms.
Answer:
1. 2AgO2 --> 4 Ag + O2
2. Decomposition
3. 2NaBr + CaF2 --> 2NaF + CaBr2
Explanation:
Explanation:
They are indeed placed from the far left hand side of the periodic table in almost the same column. If you step around the table between left to right, the movement of electrons rises by one. When you progress down the line, the number of power increases by the one.
Answer:
They contain of atoms
Explanation:
That's because atomic weights or masses of each atom of each element are proportional to each other, the same number of atoms of each element will give masses that are also proportional to each other. If you start with 20 oxygen atoms, you will need 40 hydrogen atoms to make the water and you will get 20 molecules of water.
Answer:
V₁ = 374.71 mL
Explanation:
Given data:
Initial volume of gas= ?
Initial temperature = 22°C
Final temperature = 86°C
Final volume = 456 mL
Solution:
Initial temperature = 22°C (22+273 = 295 k)
Final temperature = 86°C (86+273 = 359 k)
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₁ = V₂T₁ /T₂
V₁ = 456 mL × 295 K / 359 k
V₁ = 134520 mL.K / 359 k
V₁ = 374.71 mL
