The correct answer is: an interaction between the biosphere and the geosphere.
The geosphere represents all of the rocks, minerals and ground that are found on and in Earth. It includes the ocean floor, all of the rocks on the surface, and all of the sand in the deserts.
Biosphere on the other hand is composed of all the living organisms on Earth (including human).
The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.
<u>Explanation:</u>
In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.
This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
Answer:
Neutrophils help fight infections because they ingest microorganisms and secrete enzymes that destroy them. A neutrophil is a type of white blood cell, a type of granulocyte and a type of phagocyte.
Explanation:
Neutrophils display adhesion glycoproteins on their surface to bind endothelial and subendothelial structures. They move randomly until they find a damaged site. Unless neutrophils are activated, endothelial cells do not tend to adhere. When inflammation mediators (IL-1, FNT) activate endothelial cells, they express P-selectin and E-selectin on the surface. The expression of glycoproteins and L-selectin cause the initial adhesion of the non-stimulated neutrophil to the activated endothelium, slowing it down by rolling it over the endothelium. Activated endothelial cells, opsonized particles, immune complexes, FEC-G, FEC-GM and chemoattractants produce factors that stimulate neutrophil activation. Expressing β2 integrin (endothelium adhesion molecule) Neutrophils expand and form pseudopods. Neutrophil activation also promotes degranulation, superoxide generation, and arachidonate metabolite production.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
