Transgenic organisms are those that have had their genomes altered by external means. These organisms are found in applications of genetic engineering, but they are only useful if the inserted gene is expressed in the organism.
An example of a transgenic organism may be a rat with the gene for hemoglobin from a rabbit. This rat is only useful if it indeed does produce rabbit hemoglobin in its blood due to the inserted gene.
Answer:
The soil property that is been observed is SOIL TEXTURE.
Explanation:
There are different types of soil and each one has its unique characteristics. The characteristics of soil include: texture, structure, porosity, chemistry and colour.
Soil texture refers to the property of the soil, which indicates the relative constituent of various particles of diverse sizes that are present in the soil. The soil textures determines the amount of air and water a soil can hold and influence the rate at which water pass through its particles. It also determines the ease with which the soil can be worked upon. Soil texture can be determined by rubbing the soil particles on one's fingers.
Answer:
Anaerobes are not able to have growth in the presence of much of oxygen environment as they do not have catalse .Catalse is the enzyme for clearance of oxygen.There are also anaerobes protects their own self from oxygen by production of an enzyme known as super oxide dismutase. Therefore, it is not easy task for creation an oxygen-absent environment for anaerobes in the vitro so they cannot be grown in vitro.
This is an example of developmental homology. Studying embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. Homologous structures are those structures whose underlying similarity arises from their being derived from a common ancestral origin while analogous structure are those whose similarity comes from their performing of a similar function.
