A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a sequence of DNA or RNA. Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.

Answer:
The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis.
Explanation:
Correct answer: A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
The ant and aphids have mutualism type of relationship because they both profit from one another. The aphids are protected while the ant is fed.
<h3>What is Mutualism?</h3>
- Mutualism is a partnership in which both species participate and gain from it.
- In this instance, ants profit because they eat the waste products left behind by aphids, while aphids profit because ants guard them.
- An illustration of a mutualistic relationship is the one between an animal called an oxpecker and a rhinoceros or zebra.
- The spider crab continues to be hidden from predators.
- Bees with flowers - Another mutualistic link exists between bees and flowers.
- Bees move between flowers to collect the nectar they require to produce honey.
- Pollination occurs when the bee transfers pollen from one plant to another.
