A habitat defines the interaction of organisms with the other factors, which can be living or non-living, while niche describes how that specific organism is linked with its physical and biological environment. Habitat is the part of the ecosystem, while niche plays an important role in the formation of an ecosystem.
The generally widely accepted first step of the scientific method is to ask a question.
This is where you think of a question which you want to do an experiment on, and then later on conduct an experiment to answer that question.
<h2>Answer:</h2>
Option C is correct.
C. Annelida and Arthropoda
<h2>Explanation:</h2>
Annelida and Arthropoda are the phyla belong to the kingdom Animalia. In these both phylum animals are consist of segmented bodies. But the animals in Annelida consists of a hydrostatic skeleton whereas the animals in Arthropoda consist of exoskeleton made up of chitin.
Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
