The correct Answer is:
To determine whether the observed animal is an insect or an earthworm, we need to identify the key characteristics that distinguish insects from earthworms. Here's a step-by-step solution: ### Step-by-Step Solution: 1. **Identify the Phylum**: - Insects belong to the phylum **Arthropoda**. - Earthworms belong to the phylum **Annelida**. 2. **Key Characteristics of Insects**: - Insects have **jointed legs**. This is a defining feature of the Arthropoda phylum. - Insects typically have a segmented body, but the segments are not as pronounced as in earthworms. 3. **Key Characteristics of Earthworms**: - Earthworms have a **cylindrical body** and exhibit **metameric segmentation**, which means their body is divided into segments. - Earthworms do not have jointed legs. 4. **Comparison of Features**: - Both insects and earthworms are **bilaterally symmetrical**, so this characteristic does not help in distinguishing between them. - The presence of **jointed legs** is a clear indicator that the organism is an insect. - A **cylindrical body** and **segmentation** are characteristics of earthworms. 5. **Conclusion**: - Since the observed animal has jointed legs, we can confirm that it is an **insect**. ### Final Answer: The characteristic that confirms the observed animal is an insect is that it has a **body with jointed legs**. ---

Any deviation from the perfectly ordered arrangement constitutes a defect or imperfection. The compounds in which the number of irregularity are present in the arrangement of atoms or ions are called atomic imperfections or point defects. These may be stochiometric or non - stoichlometric. Stoichiometric defects are further classified into Schottky defects in which number of positive and negative ions are missing in equal ratio and Frenkel defects in which an ion leaves its correct lattice sites and occupies on interstitial site. Schottky defect is more common in ionic compounds with high co-ordination number and where the size of positive and negative ions are almost equal, while in Frenkel defects are common in ionic compounds, which have low co-ordination number and in which there is large difference in size between positive and negative ions. Which of the following defect, if present, lowers the density of the crystal ?
