Explanation / Answer

Answere :

Question 1 : All above statements are seems to true about evolution.

Question 2 : The correct option is (a) i.e DNA->mRNA->protein because the DNA codes for mRNA and synthesis occur through transcription. mRNA contain information for protein synthesis in the form of codons. The protein synthesis from mRNA occur through translation.

Question 3 : The correct option is (b) i.e. A cetain group of animals accumulate adaptation overtime, making them better suited to thier envirnoment.

Question 4 : The correct option is (c) i.e. evolution because antibiotic resistance is a consequence of evolution.

Antibiotic action is an envirnoment pressure, those bacteria which have a mutation allowing them to survive will live on reproduce. They will then pass this trait to the offspring, which will become antibiotic reistance.

Question 5 : The incorrect option is (b) i.e. they are a type of lipid because enzymes are not a type of lipid, they are proteinaceous in nature.

Question 6 : The correct option is (d) i.e. scanning electron microscopy technique is used for study of surface of cells.

Question 7 : The correct answere is (c) i.e Endosymbiont theory because this theory believe that chloroplast and mitochondria are independent structure because they contain its own DNA and ribosomes and somehow enter into eukaryotic cell.

Question 8 : The correct option is (e) i.e mitochondria.

Question 9 : The correct option is (c) i.e ribosomes because prokarytes has 70 S ribosomes and eukaryotes has 80 S ribosmomes.

Question 10 : The correct option is (c) i.e.N2.
