The mode of reproduction that requires a single parent and produces offspring that are genetically the same as the parent is - asexual reproduction

sexual reproduction

unicellular reproduction

prokaryotic reproduction

Asexual reproduction

Example:

Strawberry plants reproduce asexually through runners in the soil that sprout to create new strawberry plants.

After asexual reproduction, the newly produced organism will look identical to the parent being as only one parent was involved, therefore only one set of genes was introduced not making a genetic differece.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
