Correct Answer: TRUE
Explanation:
Carcinomas are cancers that begin in tissues lining the inner or outer surfaces of the body where the DNA of the cells become damaged. Lung cancer and one type of skin cancer (squamous-cell carcinoma) are carcinomas.
Hence, the given statement is TRUE.
Correct Answer: All the above
Explanation:
Carbohydrates, together with lipids, proteins and nucleic acids, are one of the four major classes of biologically essential organic molecules found in all living organisms. They not only provide energy for vital metabolic reactions but also supply the building materials for normal structure, growth and repair. Your body needs relatively large quantities of carbohydrates, fats and protein for optimal function, hence their classification as macronutrients.
Correct Answer: Magma emplacement
Explanation:
sedimentary features all are related to water deposited minerals and rocks.
Which of your choices has nothing to do with water is not a sedimwntary structure. Here in the given choices Magma emplacement is not a sedimentary structure.
Correct Answer: Retinol
Explanation:
Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids.

Vitamin B2 - Riboflavin
Vitamin B3 - Niacin
Vitamin B5 - Pantothenic acid
Vitamin B6 - Pyridoxin
Vitamin B7 - Biotin
Vitamin B9 - Folic acid
Vitamin B12 - Cyanocobalamin

Vitamin E - Tocoferol
Vitamin K - Phylloquinone and Menaquinones
Correct Answer: All the above
Explanation:
Viruses are responsible for some of the most dangerous and deadly diseases including influenza, ebola, rabies and smallpox.
Despite their potential to kill, these potent pathogens are in fact considered to be non-living.
Reasons:
1. Viruses don't have any cells, like living organisms do. They have protein coats but no organelles or other cellular machinery. Just a little DNA packet.
2. Viruses can't produce new proteins, DNA, or RNA and therefore are unable to reproduce on their own. They need infected cells' machinery to make all of these and produce new virons.
3. Viruses have no metabolic activity. They don't use or convert energy and have no ongoing interior processes. They're basically just inert structures until they impact a potential host cell.
Correct Answer: Triglycerides
Explanation:
Triglycerides are the primary form of dietary fat found in the body, and may contain a combination of three fatty acids:
saturated fatty acids (SFAs),
polyunsaturated fatty acids (PUFAs), or
monounsaturated fatty acids (MUFAs).
Correct Answer: Matching blood group before marriage is important This is to prevent Rh incompatibility Rh incompatibility can lead to erythroblastosis fetalis (Hemolytic disease of the newborn-HDN) Fetal RBC gets destroyed & newborn may get severe anaemia, jaundice This jaundice is more severe than Physiological jaundice ( which is the most common and will usually resolve on its own) In very severe form, a fetus may die due to heart failure This is mediated by the antigen-antibodies reaction Transfer of maternal antibodies across the placenta occurs This happens when Rh +ve man marries Rh-ve lady So Rh +ve man should try to avoid marrying Rh-ve lady Matching blood groups for marriage :: Boy : A = Girl : A & AB Boy : B = Girl : B & AB Boy : O = Girl : O, A, B & AB Boy : AB = Girl : AB Boy : Rh+ve = Girl : Rh+ve Boy : Rh-ve = Girl : Rh+ve & Rh-ve Blood groups that do not match for marriage :: Boy : A = Girl : O & B Boy : B = Girl : O & A Boy : AB = Girl : O, A & B Boy : Rh+ve = Girl : Rh-ve
Correct Answer: Colors
Correct Answer: FALSE
Explanation:
The given statement that a calorie is another term for carbohydrate is False.
Carbohydrates are one of the main types of nutrients, and are most important source of energy.
Where as Calorie is a measurement of how much heat energy is generated by the body processing food.
Your digestive system changes carbohydrates into glucose(blood sugar). Your body uses this sugar for energy.
Correct Answer: Agriculture
Explanation:
Agriculture would be a good example of a purely competitive industry.
