Answer: it’s 10%
Explanation: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.
A depressant is the chemical substances that have a calming effect on people. They are also called sedatives or tranquilizers. The correct answer is 2.
Kinetic energy is absorbed and converted to potential energy in an endothermic reaction.
DNA is an example of a complex biological polymer called a nuclei acid. Nucleic acids are made up of many smaller sub units called nucleotides. The components of a DNA nucleotide are deoxyribose, phosphate group, nitrogen group. There are four possible bases in a DNA molecules which includes adenine, cytosine, guanine and tymine.
Combining DNA from different sources is the definition of Recombinant DNA or rDNA. This is what is more commonly referred to as genetic engineering. The applications for this technology are vast, but very expensive. The use of Recombinant DNA has seen applications in agriculture where plants are given immunity to certain diseases or molds from another plant which is resistant or where human DNA is combined with forms of bacteria to produce a more natural insulin for people who are diabetic.
