Explain Biofuels.
4/19
Fuels produced from biological materials, such as plant or animal waste, that can replace fossil fuels and reduce greenhouse gas emissions.
5/19
What is the process of Transesterification?
5/19
A chemical process that converts vegetable oils or animal fats into biodiesel by reacting them with an alcohol in the presence of a catalyst.
6/19
Name a common example of bioplastics.
6/19
Polyhydroxybutyrate (PHB), produced by microbial fermentation of sugars, is an example of a biodegradable plastic.
7/19
What is CRISPR-Cas9?
7/19
A genome editing technology that allows scientists to alter DNA sequences and modify gene function easily and precisely.
8/19
Differentiate between Autograft and Allograft.
8/19
Autograft involves transplanting tissue within the same individual, while Allograft involves transplanting tissue from one individual to another of the same species.
9/19
Define Nanobiotechnology.
9/19
The application of nanotechnology in the field of biology, particularly for the development of materials and tools for medicine and therapy.
10/19
What are Organoids?
10/19
Miniaturized and simplified versions of organs produced in vitro that replicate some functions of real organs.
11/19
Importance of Genetic Engineering in Agriculture.
11/19
It allows for the development of crops with enhanced traits such as disease resistance, drought tolerance, and improved nutritional profiles.
12/19
What role do Microalgae play in biotechnology?
12/19
Microalgae are used in biofuel production and bioremediation due to their fast growth and ability to consume CO2 and nutrients.
13/19
What is Enhanced Oil Recovery (EOR)?
13/19
A set of methods to increase the amount of crude oil that can be extracted from an oil field, often using microbial techniques.
14/19
Explain the term Synthetic Biology.
14/19
An interdisciplinary field that combines biology and engineering to design and construct new biological parts, devices, and systems.
15/19
What is the significance of 'Roundup Ready' crops?
15/19
These genetically engineered crops are tolerant to the herbicide glyphosate, allowing farmers to control weeds without harming the crops.
16/19
How does Ethanol function as a biofuel?
16/19
Ethanol, derived from fermentation of sugars, can be blended with gasoline to create a cleaner burning fuel alternative.
17/19
What is a 'Xenograft'?
17/19
A transplant of organs or tissues from one species to another, such as pig valves used in humans.
18/19
Identify a challenge in using CRISPR technology.
18/19
Off-target effects, where unintended parts of the genome are modified, poses a major challenge to the safe application of CRISPR.
19/19
List an application of Nanotechnology in Medicine.
19/19
Nanoparticles can be used for targeted drug delivery systems, improving drug efficacy and minimizing side effects.
