Explanation:
Reproductive system is the system of an organism encompassed with the function of giving rise to new offsprings. In sexual reproduction, which involves two organisms, one of the organisms is usually a MALE while the other is a FEMALE.
In most sexually reproducing organisms, the female reproductive system undergoes a division called MEIOSIS to produce a sex cell or gamete called EGG CELL. This egg cell gets fertilized by the sperm cell produced by the male to form a zygote. Hence, EGG CELL is the female reproductive system cell.
The fossils which are plants and animal remnants change over time. The Law of Superposition is a law that governs the geochronology, which states that in any undisturbed sequence of rocks deposited in layers, the youngest layer can be found on the top and the oldest can be found at the bottom, with each layer being younger than the one under it and older than the one above it.
These elements works in a synergy to explain and to help persons of interest understand the idea of evolution which stresses out that the modern day species came from a distinctively different species.
In biology, the biotic factors pertain to the living components of Earth while the abiotic factors are those non-living chemicals and physical factors. The only choice that is not an interaction between biotic and abiotic factors is the third choice, "C. male elk fighting over a female".
