The correct answer is water pollution.
The leading cause of limited water supply is water pollution.The overall amount of water on earth is same. The shortage of water lies when it comes to fresh water is used for domestic purposes.
The main cause of limited supply of water is water pollution. Due to pollution the water left for use is restricted as polluted water cannot be used as potable water or commercial purpose.
The pollutant from industries, house, agricultural, pesticides and oil spills are discharged in water bodies which makes it polluted and unfit for use.
B) molecular homology (comparing DNA)
C) identifying and comparing homologous structures
D) comparative embryology (comparing embryonic development)
Answer: The correct answer is -
B) molecular homology (comparing DNA).
DNA (deoxyribonucleic acid) is considered as the genetic material of living organisms, which is passed from one generation to the next generation that is from parents to their offspring.
By comparing the DNA sequence of two organisms (molecular homology), we can determine whether they are closely related or not.
If two organisms share genetic relatedness that is similarity in their DNA sequence, they are considered to be closely related.
Thus, option B) is the right answer.
Answer:

Explanation:
Answer:
-30 N
Explanation:
Every living organism has a scientific name that is classified into several hierarchical groups, including domain, kingdom, phylum, class, order, family, genus, and species. This classification system helps scientists organize and understand the diversity of life on Earth.
1. Domain: This group represents the highest level of classification and categorizes organisms into three domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria contain prokaryotic organisms, while Eukarya includes eukaryotic organisms.
2. Kingdom: Within each domain, organisms are further classified into different kingdoms. For example, in the domain Eukarya, there are kingdoms such as Animalia, Plantae, Fungi, Protista, and more. Each kingdom includes organisms with similar characteristics and evolutionary relationships.
3. Phylum: The phylum is the next level of classification and groups organisms based on certain shared characteristics. For example, in the animal kingdom, phyla include Chordata (which includes vertebrates) and Arthropoda (which includes insects, spiders, and crustaceans).
4. Class: Within each phylum, organisms are further divided into classes based on additional shared characteristics. For example, in the class Mammalia, animals have mammary glands and give birth to live young.
5. Order: Orders are the next level of classification and further divide organisms within a class based on shared characteristics. For example, within the order Carnivora, animals have specialized teeth for eating meat.
6. Family: Families group organisms within an order based on more specific shared characteristics. For example, within the family Felidae, animals have retractable claws and are known as cats.
7. Genus: The genus is a more specific classification group that groups closely related species together. For example, the genus Panthera includes big cats such as lions, tigers, and leopards.
8. Species: The species is the most specific level of classification and refers to a group of organisms that can interbreed and produce fertile offspring. Each species has a unique scientific name, consisting of the genus and species names. For example, the scientific name for lions is Panthera leo.

B.Ecology is a practice that emphasizes preservation of life.
C.Ecology is an area of study that focuses on interactions in nature.
D.Ecology is a strategy for sustainable living.
A. Sun
B. Sand
C. Wind
D. Oil
Correct answer: D). Oil
Fossil fuel is a type of fuel that is formed by the natural process like anaerobic decomposition of dead organisms. These are formed after millions of years when the dead bodies of plants and animals are buried under the rock. Heat from the internal earth and pressure from the rock changes this fossil into the natural gas and cola etc.
Hence, the correct answer would be option D.
