Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.
Explanation:
I think the conclusion would be that the fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.A barnarcle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustecea, and thus related to crabs and lobsters. B. balanoides is a barnacle that attaches to rocks, especially during intertidal zones while C.stellatus is a species of acorn barnacle common on rocky shores in south West Eangland, Ireland, and Southern Europe.
A. Amber, because in the Prehistoric times the insects and small dinosaurs fell into amber and became preserved in the hardened sap.

Rectum.
Accessory digestive organs: liver, gallbladder, pancreas.
Answer:
The correct answer would be C.) The cell grows and makes a copy of its genetic material.
Cell cycle can be divided into two phases namely; inter-phase and mitotic phase.
Inter-phase or resting phase is the phase occurs between two consecutive mitotic phases.
It is sub-divided into three phases:
Gap 1 (G₁) phase: The cell actively performs its functions during this phase. It grows in size, transcribe and translate all the enzymes, proteins and other components which are necessary for replication of DNA (deoxyribonucleic acid).
Synthesis (S) phase: It is the phase during which DNA content of the cell is replicated or synthesized. After this phase, the DNA content of the cell doubles however, the chromosome number remains the same.
Gap 2 (G₂) phase: The cell resumes its growth and prepares itself for cell division or mitotic phase. The cell organelles like mitochondria and chloroplasts (in plants) also divide during this phase. The cell continues to grow until it enters mitotic phase.
Hence, we can conclude that the cell grows and makes copy of its genetic material ( usually DNA) before mitosis.
