It's because every living cells do respiration. Respiration basically involves the oxidation of food(carbohydrate) to generate energy in form of ATP.
Answer:
Top left: RR Top right: Rr Bottom left: Rr Bottom right: rr
Explanation:
if both parents are heterozygous then the table will always look like this. the chances of the offspring being heterozygous are 50%. the offspring has a 25% chance of having two recessive traits and a 25% chance of having two dominant traits.
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄
<h3>Further explanation </h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
For simple equations, you can experiment with the balance of the number of atoms on the left and right
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄
aFe+bO₂⇒Fe₂O₃
Fe , left=a, right=2⇒a=2
O, left=2b, right=3⇒2b=3⇒b=3/2
the equation :
2Fe+3/2O₂⇒Fe₂O₃ x2
4Fe+3O₂⇒2Fe₂O₃
aCO₂+bCl₂⇒O₂+CCl₄
C, left=a, right=1⇒a=1
Cl, left=2b, right=4⇒b=2
O, left=2a, right=2⇒2a=2⇒a=1
the equation :
CO₂+2Cl₂⇒O₂+CCl₄
