Answer:
The correct answer would be hydrologic cycle (hydro means "related to water").
Hydrologic cycle or water cycle refers to the cyclic movement of water in an ecosystem.
The physical processes involved in the cycling of water throughout the ecosystem are: evaporation, condensation, sublimation, precipitation, infiltration, and runoff (surface and sub-surface).
Water evaporates from the surface of the earth into the atmosphere where they condense to form clouds. When temperature decreases, the water droplets merge with each other to form bigger droplets which are precipitated in the form of rain.
Water can also precipitate in the form of snow, fog, hail sleet et cetera.
Water fall on the earth surface either infiltrate to form ground water or runoff the surface to from lakes, rivers et cetera.
The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.
Snow covers tundra lands for the majority of the year, but summer provides bursts of wildflowers.
The small plants of the tundra employ dormant strategies, producing seeds only occasionally, turning with the sun to absorb energy, and growing protective coverings.
The ability to build subterranean insulated tunnels as well as heavy winter coats, seasonal color-changing camouflage, and efficient body shapes have all been developed by animals that live in the Arctic tundra.
Therefore, The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

Answer: Plants and animals are able to survive in the tundra because they have adaptations that allow them to thrive in the harsh conditions of the Arctic and sub-Arctic regions. These adaptations include thick fur or feathers to insulate against the cold, small body size to minimize heat loss, and the ability to store food and nutrients during the short growing season. Additionally, many tundra plants have shallow roots that can absorb nutrients quickly when they are available, and some have developed the ability to photosynthesize at low temperatures and with minimal sunlight.
A larger brain allows humans to solve complex problems.
The size of the human brain has changed randomly over time due to mutations.
A large brain increases humans’ ability to fight and survive disease.
Answer:
A large brain allows humans to solve complex problems.
Explanation:
The large brain in humans has enabled them to solve a complex problem in of the real world and also enabled them to survive more as compared to humans with the smaller brains.
In seven million years the size of the human brain is tripled. That allows them to store and process a huge amount of information and also help to interact with the people in the surrounding better.
Hence, the correct answer would be option B.
Answer:
c) Electron microscopy
Explanation:
Electron microscopy (EM) is a technique for obtaining high-resolution images of biological and non-biological specimens.
the answer is c my dude
b. They exhibit metastasis.
c. They respond to growth inhibitors.
The cancer cells exhibit the property of metastasis. Option B is correct.
Metastatic cancer is a type of cancer that spreads from one area of the body to another. Many types of metastatic cancer are also called stage IV cancer. Metastasis is the process of cancer cells spreading to other areas of the body. The cells spread away from the place of origin of the tumor to other parts of the body.
Metastasis involves the following stages: 1. Local Inference of Tumour Cells 2. Transendothelial Migration of Cancer Cells into Vessels 3. Survival in the Circulatory System 4. Extravasation 5. Proliferation in Competent Organ Systems.

B) commensalism
C) symbiosis
D) interaction
The right option is; A) coevolution
Coevolution is the term that refers to a change in one species that results from a change in another species that it interacts with.
Coevolution is a process of mutual evolutionary change that takes place between two or more organisms as they interact with one another. Under this process, any change in any of the organisms that are involved in the interaction influences others evolution. Coevolution can happen in interactions such as between host and parasites, predators and prey and mutualism.
