B. genetic drift
C. sexual selection
D. gene flow
Adaptive evolution means evolutionary changes in an organism that make it suitable for its habitat. Natural selection is the factor that can lead to evolution for change in body color that enabled animals to better hide from predators.
A genetic trait that helps organisms to increase their reproductive success are adaptive traits. It is a type of natural selection.
Adaptive evolution can be done by following process:
Thus,the correct option is A.

Answer:
Stem cells are special human cells that are used to repair damaged tissues
Answer:
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and divide indefinitely to produce more of the same stem cell. Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them. Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.
Mold is a biotic component of the environment. It's a living organism that contributes significantly to the decomposition of dead matter. While molds are influenced by abiotic factors such as sunlight and salinity, they are themselves living and thus part of the biotic factors.
Mold is a biotic component, which means it's a living part of the environment. It consists of multicellular organisms that play critical roles in the decomposition of dead plants and animals. While they can be found in various environments, molds are categorized by their ability to grow as long filaments that form visible colonies.
Molds are critical to the life cycle and energy exchange in many ecosystems, contributing to critical biological processes. Abiotic factors, such as salinity and sunlight, influence the distribution and prevalence of molds in various ecosystems, but these are non-living components of the environment.
Simply put, molds are important organisms that contribute to the decomposition process and are considered part of the biotic factors in an environment due to their living nature, unlike abiotic factors such as water, air, soil, sunlight, and salinity.

Answer:
D.Rocks and Sediments
Explanation:
Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. These are the reservoirs, or sinks, through which carbon cycles. The ocean is a giant carbon sink that absorbs carbon.
