Answer:

1. There is a small sample of the disease that's being tried to prevent so that the body can get used to fighting it.

2. In the vaccine there is a small sample of a disease that the vaccine is being used to prevent. The white blood cells fight harmful bacteria and so prevent diseases.

3. A vaccine works by training the immune system to fight viruses or bacteria.

4. The antigenic variability of the virus and other viruses and bacteria acts as infective agents.

Suppose that the farmer is growing rice crop. If he bought 5 kg seeds at Rs. 100 per kilogram, then how much net money will he g
ANEK [815]

Answer:

The net money the farmer will get

= Rs. 39,500

Explanation:

The farmer bought 5 kg seeds of rice at Rs. 100 per kg.

Cost price = 5 × 100 = Rs. 500

And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg

Selling price = 1000 × 40 = Rs. 40,000

The farmer's net profit

= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500

Hope this Helps!!!

Lapatulllka [165]

Answer:

B) fats

Explanation:

Common hepatic duct is s the part of the biliary tract which means that is involved in the secretion of bile.

Bile salts secreted from the bill have an important role in emulsification of lipids (fats). They have the ability to aggregate around lipids thanks to their amphipatic nature. Amphipatic nature means that they have hydrophobic side which binds directly to lipids and hydrophilic side which are faced outwards. Lipids enveloped with bile salts are called micelles.

Formation of micelles increases the surface area of fat, which is appropriate for the the action of the enzyme pancreatic lipase (perform digestion of triglycerides).
