D.
Explanation: Ecology: relation of organisms with one another or their surroundings.
Answer:
Answer is B. It did not reflect the actual evolutionary relationships among organisms very well.
Explanation:
The five-kingdom system of classification was initiated or formed by Robert H. Whittaker in 1969. And it involved the Kingdoms monera, fungi, protista, animalia and plantae.
This classification system was regarded as not so good because of placement of some certain organisms. For example, in the classification system, unicellular algae were put under the kingdom protista, when other multicellular organisms like algae were being classified under the kingdom Plantae.
Some names are:
Raw cotton - Textiles
Limestoe - Cement
Iron ore - Steel
Bauxite - Aluminium
Wool - Woollen cloth
Soya seed - Soil oil
Mustard seed - Mustard oil
Ground nut - Ground nut oil
Sugar cane - Sugar
Hides and skins - Leather
Naphtha - Petrochemicals
Answer:
Destrucción de hábitats naturales, tanto terrestres como marinos y otros acuáticos. Destrucción de ecosistemas de todo tipo. Extinción de especies animales y vegetales. Interrupción de las redes y relaciones tróficas.
Explanation:
The forearm of birds, reptiles, and humans illustrates a homologous body structure.
- Similar physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.
- The limbs of humans, cats, whales, and bats are examples of homologous structures.
- All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure.
- The arms of a person and the wings of a bat are excellent examples of homologous structures. Because both bats and people are mammals, they have a common ancestor.
- Even though they appear considerably different from one another from the outside, a bat's wing and a human arm have remarkably comparable internal bone structures.
- Wings help bats fly, whereas arms enable human interaction with their environment. The wing and the arm also have various purposes.
