Question 1

Energy is measured in units called

Accepted Answer

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.

Question 2

Wild animals are not considered a natural resource.

Accepted Answer

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.

Question 3

Why are viruses considered to be nonliving?

Accepted Answer

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.

IUPAC Name :: (2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohexen-1-yl)nona-2,4,6,8-tetraen-1-ol Vitamin Name - Chemical Name Vitamin A - Retinol Vitamin B1 - Thiamine Vitamin B2 - Riboflavin Vitamin B3 - Niacin Vitamin B5 - Pantothenic acid Vitamin B6 - Pyridoxin Vitamin B7 - Biotin Vitamin B9 - Folic acid Vitamin B12 - Cyanocobalamin Vitamin C - Ascorbic acid Vitamin D - Calciferol Vitamin E - Tocoferol Vitamin K - Phylloquinone and Menaquinones

Question 5

Which of the following is not a sedimentary structure?

Accepted Answer

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.

Question 6

Carbohydrates, lipids and proteins are classified as

Accepted Answer

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.

Question 7

Both skin and lung cancer are classified as carcinomas.

Accepted Answer

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.

Question 8

What is the primary form of fat in the diet?

Accepted Answer

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).

Question 9

A calorie is another term for carbohydrate.

Accepted Answer

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.

Question 10

Which of the following industries most closely approximates pure competition?

Accepted Answer

Agriculture would be a good example of a purely competitive industry.

Question 11

Lacto-ovo vegetarians would not eat

Accepted Answer

Lacto-ovo vegetarians who eat milk products and eggs but would not eat Meat, poultry, fish.

Question 12

Proteins are made where in the cell

Accepted Answer

Ribosomes are the sites where proteins are synthesised. The transcription process where the code of the DNA is copied occurs in nucleus but the main process of translating that code to form other protein occurs in ribosomes.

Question 13

Which of the following processes includes all others?

Accepted Answer

Passive transport Process includes all other process like facilitated diffusion, osmosis and diffusion of a solute across a membrane.

Question 14

Where is the DNA located in a eukaryotic cell?

Accepted Answer

In eukaryotic cells, DNA is located in the nucleus, chromosomes and the mitochondria. Most of the DNA is present in the nucleus and some amount in the chromosomes and mitochondria.
