Populations evolve and individual organisms do not. Evolution occurs through natural selection and survival of the fittest as populations evolve traits that better suit their environment.
<em>In Roosevelt's speech, some of her main ideas are:</em>
'It would be better if people were not so busy competing with each other
'The role of women is changing'
'a good home life is based on strong relationships'.
Answer
Gametes that fertilize an ovum are called the sperms
Explanation
The reproductive cells of an organism are called the gametes or sex cells. Female sex cells are the ova/egg where as male sex cells are the sperms. The sperms are stored in the scrotum after their production in the male testes where as the eggs for females mature in female ovaries. During fertilization, sex cells meet in the Fallopian tube.

change in temperature and pH can change the shape of the enzyme and They can break down the reactants
Temperature. Higher temperatures typically result in faster rates of reaction, whether they are enzyme-catalyzed or not. The chemical bonds in the active site, however, can be impacted by temperature changes that are either too high or too low and make them less able to bind substrates. Extremely high temperatures (over 40 degrees Celsius may cause animal enzymes to denature, losing their form and activity)
pH can also affect enzyme function. The acidic or basic characteristics of active site amino acid residues are frequently crucial for catalysis. These residues can be impacted by pH changes, which can make it difficult for substrates to bind. Like with temperature, certain pH ranges (acidic or basic) can cause enzymes to denature. Enzymes function best within these pH ranges.
