Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.
Answer:
The three types of rocks are Igneous, Sedimentary, and Metaphoric.
Explanation:
<em>Igneous</em> rocks are formed out of melted rocks deep inside the Earth. A distinguishing unique characteristic is that they are hard.
<em>Sedimentary</em> is formed from layers of sand, silt, dead plants, and animal skeletons. A distinguishing unique characteristic is that they are easy to crumble.
<em>Metaphoric </em>are formed when minerals change through heat and pressure underground. Two distinguishing unique characteristics are that they may have many layers and are noticeably hard.
50% of the offspring would be green.
In biology, the strain is a low-level taxonomic rank used in different contexts:
In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.
In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.
A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).
Answer:
Explanation:
Humidity is the measure of the amount of water vapor in the air.
Areas with a large amount of surface water have high humidity levels.
.Warm tropical areas have very humid air.
