Answer:
The correct answer will be option-
Hydrogen (atom) →water (molecule)→ liver (organ) →skin (cell) →elephant (organism) → wolf pack (population) → tropical rainforest (ecosystem) →planet Earth (Biosphere).
Explanation:
The biological level of organization is the arrangement of the matter from the smallest to the largest in the hierarchy.
The smallest unit of matter is the atom which forms the molecules. These molecules together form the organelles which aggregate and form the basic unit of life called cell. The cells aggregate-gate and perform the same functions to form tissues which together form the organs. These organs constitute the organ system which forms the organisms. The organism together forms the population which form the community. The community becomes a part of the ecosystem which forms the largest level called the biosphere.
On the basis of this, the given options are arranged.
Answer:
B Tundra.
Explanation:
Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
The tongue has a lot of taste buds on it. These taste buds contain the sensory receptors that respond to the food particles. The sensory receptors emit an electrical signal that is carried by the sensory neurons present in the tongue to the brain. The brain has a lot of inter-neurons that help in processing the signal and form bridge between the sensory and motor neurons. The brain analyses and decodes the taste from the electrical signal and relays an output through the motor neurons to the muscles present in the tongue and the cheeks to spit the sour milk out.
