Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.
Answer:
The correct answer is C Speed or velocity of the reaction
Explanation:
Enzymes are homogenous,biological catalyst that is used to speed up the reaction.
Enzyme do this by decreasing the energy barrier also called activation energy of the reactants but do not hamper the reaction equilibrium.
The enzyme itself remain unchanged throughout the overall reaction.
Answer: unlike modern-day evolutionary geneticists, Darwin did not have the knowledge of modern-day genetics or the ability to sequence the genome. So, Darwin couldn’t have determined that the trait of flightless wings was likely caused by a genetic mutation.
