There are two questions (1 and 2), answer are provided as such. The cha
Answer to Question 1
Population --> Whole Organism --> Organ system --> Organ --> Tissue --> Cell
Explanation:
- The cell is the simplest, basic and functional unit of life.
- Tissue is a collection of similar cells e.g brain tissue
- Organ is a collection of similar tissues e.g Liver, Lungs
- Organ system refers to a group of closely related organs performing the same function in an organism.
- Organism comprises of well-coordinated organ systems.
- Population refers to the total number of organisms living and breeding together.
Answer to Question 2
Cell --> Genome --> Gene --> Nucleotide
Explanation:
A cell consists of a nucleus and other organelles. Within the nucleus & other organelles like mitochondria lies the total genetic material of the cell known as GENOME.
- The genome contains several functional sequence of bases known as GENE.
- A gene is made of triplets of nucleotides (codons)

Why are there so few humans and animals in the desert?</h2>
A desert is defined as a place with a hot and dry temperature, little or no rainfall (less than 25 cm), a barren landscape, a lack of water, and dry soil. There is very little vegetation. Plants appear only after rain, are seasonal, and have a short lifespan. Dust storms and shifting dunes may be dangerous. In other words, the circumstances are unfit for human occupancy. That is why relatively few people live in or near deserts. Animal life is likewise sparse, yet abundant in some areas. Some locations, such as Egypt's Nile Valley, may be heavily inhabited if enough water is available. In reality, air-cooling, air-conditioning, and irrigation facilities, as well as the discovery of petroleum wherever and whenever it was accessible, have made desert life more pleasant, dynamic, and have drawn people from outside, such as the Gulf area.
<h2>Why don't desert animals just move somewhere greener?</h2>
Deserts are a result of the Earth's atmosphere. Do you notice how deserts appear to be in similar zones? This is due to the tight link between deserts and rainforests. So this is what generates a desert, not what attracts or maintains animals here. Plants bring them and keep them alive. As plants adapt, so do animals, and the desert creates a complete ecosystem. They do not depart since they have adapted to their surroundings.
