- Question
Carbohydrates, lipids and proteins are classified as
Options- A. Macromolecules
- B. Biomolecules
- C. Macronutrients
- D. All the above
- Correct Answer
- All the above
ExplanationCarbohydrates, 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.

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: FALSE
Explanation:
Natural resources are resources taken from nature to satisfy our needs. As wild animals are on the earth naturally, they are considered as natural resources.
Hence, the given statement is false.
Correct Answer: Joules
Explanation:
Energy is measured in units called Joules.
Joule is unit of work or energy in the International System of Units (SI) which is equal to the work done by a force of one newton acting through one metre.
1 Joule = 107 ergs or 0.7377 foot-pounds.
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: Photoautotrophs are those organisms that can make their own food using sun light with the help of the process of photosynthesis Plants can prepare their own food using sunlight Hence they are Photoautotrophs
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
