Choose the correct answers from the alternatives given.
Which of the following combinations of phyla and characteristics is incorrect?

  1. Nematodaround worms, pseudocoelomate

  2. Cnidariaradial symmetry, polyp and medusa body forms

  3. Platyhelminthesflatworms, gastrovascular cavity, acoelomate

  4. Poriferagastrovascular cavity, mouth from blastopore

D Correct answer
Explanation

The nematodes or roundworms constitute the phylum Nematoda and have a pseudocoelom and complete digestive system. The partial, fluid-filled cavity inside the body of some invertebrates. Cnidarians have two different body plans. Both body plans have radial symmetry. A polyp, such as a hydra, sea anemone, or coral, is shaped something like a vase. Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates and have cavity only one opening to the outside which, in most cnidarians, is surrounded by tentacles for capturing prey. But Porifera does not have a gastrovascular cavity as it does not have specialized tissues and phyla with a true coelom and digestive system. The protostomes include the phyla Mollusca, Annelida, and Arthropoda but not porifera. 

So, the correct option is, 'Porifera gastrovascular cavity, mouth from blastopore'.

D Correct answer
Explanation

Biotechnology is the use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use. For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine.

B Correct answer
Explanation

Biotechnology is the use of biological processes, organisms, or systems to manufacture products intended to improve the quality of human life. The earliest biotechnologists were farmers who developed improved species of plants and animals by cross pollination or cross breeding.

Which of the following is not an antibiotic?

  1. Griseofulvin

  2. Cephalosporin

  3. Citric acid

  4. Streptomycin

  5. Both (A) and (C)
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Citric acid is a weak organic acid with the formula -CHO. It is a natural preservative or conservative which occurs naturally in citrus fruits and is also used to add an acidic or sour taste to foods and drinks. Griseofulvin is an orally administered antifungal drug. It is used both in animals and humans, to treat fungal infections of the skin and nails. Whereas cephalosporins are a group of broad spectrum, semi-synthetic beta-lactam antibiotics derived from the mould Cephalosporium. Streptomycin is an antibiotic (antimycobacterial) drug, the first of a class of drugs called as aminoglycosides to be discovered,

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The correct option is C

The rDNA technology is the formation of DNA molecules formed by the laboratory method of genetic recombination to bring together genetic material from multiple sources, creating a sequence that would not otherwise be found in the genome.

Modern biotechnology is based on

  1. Protoplast fusion

  2. Tissue culture

  3. Recombinant proteins

  4. Genetic engineering
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Modern biotechnology is based on the the methods of genetic engineering.  It is a technique which involves the introduction of foreign DNA carrying the desired gene of interest into the host organism & thus change the phenotype of the host organism.

So, the correct option is 'Genetic engineering'.
