Rotating Wall vessel bioreactors are widely used for Cartilage Tissue Engineering because they provide a favorable Hydrodynamic environment for cartilage differentiation.

Rotating Wall vessel bioreactors are widely used for Cartilage Tissue Engineering because they provide a favorable Hydrodynamic environment for cartilage differentiation. Correct Answer TRUE

RWV bioreactors have been broadly utilized for ligament TE since they give a good hydrodynamic condition to ligament separation and skeletal muscle tissue recovery. A cell suspension of separated chondrocytes was seeded in an RWV with no platform support. Following 90 days, the scientists got a 3D ligament-like tissue typified by sinewy tissue looking like the perichondrium.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resources of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity of predators and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative. Which of the following statements is/are correct regarding biopesticides? 1. They are not hazardous to human health. 2. They are persistent in environment. 3. They are essential to maintain the biodiversity of any ecosystem. Select the correct answer using the code given below.
