Answer:
<em>The correct option is A. Nucleotide sequence, human, hemoglobin</em>
Explanation:
If the segment of the DNA for the human gene is known then it will be very easy to find the gene on a database. The tags which should be used will be the nucleotide sequence, where the known sequence shall be mentioned.
Then we will choose the tag for the organism which is humans in this case. Then we will select the tag for the protein which is made by the nucleotide sequence, which is protein in this case. Hence, option A is the correct answer.
Answer:
They are thick, strong and made up of thousands of tubulin which are spiral in shape.
Explanation:
In eukaryotic cells, they have microtubules which are fibres serving as tracks for cell to cell transport and regulate the shape of a cell.
Microtubules are different from other cytoskeletal filaments because they possesses a cylindrical shape with the tube having a larger diameter of 20-25 nm as compared to microfilament that have a diameter of 3-6 nm.
Microtubules are made of subunits of proteins called tubulin named alpha and beta that is not present in other cytoskeletal filaments.
The generic name of poisonous chemicals, very often used in commercial agriculture that are used to kill organisms that either reduce the yield of crops or are harmful to animals are pesticides.
Pesticides are the chemicals used to kill the pests affecting the growth and yield of the crops. Pesticide is a broad term covering various small terms according to the pest being killed. For example insecticide, nematicide, avicide, rodenticide, bactericide, etc. Some chemicals used as pesticides are boric acid, Acephate, Deet, Propoxur, glyphosate, etc.
Commercial agriculture means growing of crops so as to sell them in the market to be utilized by the wide population of any area. Any crop can be grown at the commercial level. These crops do not reach the customers directly by the farmers, instead they are sold to whole-sellers first.
