Explanation / Answer

Answers: 7. Talking about proteins, we need to remember that they are the organic molecules those helps our body or any living organisms body to build. They are formed by the association of RNAs, namely mRNA, tRNA and rRNA. Here we can recall having the beads of strings, where amino acids comes and joins in a chain formation and makes the proteins. These peptide chains are thus the results of b) amino acids chains joined together.

8. Mitochondria’s are also known as the power house for cells. These are having a special function of making the energy molecule for any cellular processes to run. We are having our correct answer choice as a) to generate most of the cells supply, of chemical energy.

9. The fundamental genetic material of the cells is b) DNA. Almost all the living cells are having nucleus otherwise nucleoid, and everywhere the chromatin network contains pieces of information in their genetic nucleotide sequences known as Deoxyribonucleic acid. These are almost ubiquitous except some cells possess RNA as a genetic material.

10. the following levels of complexity always starts from the very basic unit, while in case of living systems the structural and functional unit are the cells; these are when placed together with similar or different types and functions same they make tissues. So here also we need to choose the option as b) cells, tissue, organelles, organs, systems.

11. The iron coating oxygen-transport mettalo-proteins are b) hemoglobin, as they have heme group and a metal binding center and they are mainly responsible to carry oxygen throughout the body.

12. Defining physiology – In a simple term a organisms bodily function; here a branch of Biology deals with bodies normal functions of living organisms, so this is basically associated with the parts. Here the correct answer will be b) The study of how the body parts work and carry out their life-sustaining activities.

13. Heart and lungs are placed in the body cavity called b) Thoracic cavity. Here in the secure place under the rib cage the heart and lungs are securely placed.
