Correct answer: C). Cells are the basic building blocks of life but do not constitute life itself
Cell theory in a biology is a scientific theory, which is universally accepted and it states that all living organism are made up of one or more cells, cell is the building block of living thing, it also states that all cell arise from ore existing cells.
The cell theory is collection of ideas and conclusion, which were given after many years of continuous research and experiment of many scientist, which tells about the cell and how it operates.
Answer:
Grain size, sorting and shape of particles in sediment or rock can influence how much empty space is available to store water (porosity) and the ability of groundwater to move through the material (permeability). Aquifers are water-bearing formations with good porosity and permeability and are important groundwater resources.
Explanation:
It is believed that the tilapia fish was introduced into the mangrove system by escaping from fisheries and aquariums by accident, but this species is also used to control the population of mosquitos to prevent outbreaks of malaria and other invasive species on which they feed.
The tilapia are highly tolerant and easily adaptable to different conditions in the mangrove ecosystem and they are highly efficient predators. This often makes them more successful in the environments where they are introduced than the indigenous species, which results in disruption of the food chain.
The negative human impact on mangroves disrupts the balance in the mangrove ecosystems, weakening the populations of different species that originate from mangrove forests. This leaves more space and resources to be exploited by the tilapia.
The strategies to control tilapia in mangrove ecosystems focus on restoring the habitat and strengthening the populations of indigenous species while decreasing the numbers of tilapia.
The species can be eradicated by selective overfishing of the species or by introducing another species into the habitat which is a natural enemy of the tilapia.
The three domain system is develop by Carl Woese and is used to classify biological organisms. Under these would be bacteria,archaea and eukaryota. There are also kingdoms namely archaebacteria,fungi, plantae, etc.The answer on this question would be letter b. archaea
