Answer:
Antigens are molecules capable of stimulating an immune response. Each antigen has distinct surface features, or epitopes, resulting in specific responses. Antibodies (immunoglobins) are Y-shaped proteins produced by B cells of the immune system in response to exposure to antigens.
B.Flammability
C.Density
D.Solubility
The answer is "opposite charges."
When clothes are removed from the dryer and cling together, it is because static electricity is created from the clothes rubbing together in the dryer. This results in an imbalance of electrical charge on the clothes, with some having a net positive charge and others a net negative charge, which makes them attract and stick to each other.
When clothes are removed from the dryer and they cling together, this is due to the presence of static electricity. Static electricity occurs when materials are rubbed together, causing an exchange of electrons. This exchange results in the materials being electrically charged. In the case of your dryer, the process of tumbling and rubbing the clothes together can strip electrons from the clothes and deposit them on other pieces.
This creates an imbalance in charge, leading to some clothes having a net positive charge and others with a net negative charge. The positively charged clothes are attracted to the negatively charged ones, and this attraction causes the clothes to stick together. The force that brings these different charged clothes together is called electrostatic force. If the clothes are damp, the presence of water molecules can suppress the charge, reducing the static cling.

B. ethylene
C. heptyne
D. Septane
Option C - Heptyne
Explanation
The longest chain of atoms in a particular molecule consists of seven carbon atoms. This molecule might be called heptane (C7H16). It can be a straight chain or can be branched. Its structure is -C-C-C-C-C-C-C-. Carbon completes its four bonds by combining hydrogen atoms. Hydrocarbons are named according to the carbon atoms. One carbon atom is methane, two containing is ethane, three is propane, four is butane, five is pentane, six is hexane, seven is heptane, eight is octane, nine is nonane and ten is decane.
Answer : The number of moles of is, moles.
Solution :
As we know that,
1 mole contains number of molecules
As, number of molecules of are present in 1 mole of
So, number of molecules of are present in moles of
Therefore, the number of moles of is, moles.
Answer:
Yes, this is possible.
Explanation:
It is possible that a cup of tea and teapot filled with tea has the same thermal energy. This often occurs in the real world, when two different thermal energy bodies are placed next to each other.
When two bodies are placed next to each other and these two bodies have different temperatures, there is a transfer of thermal energy between them, which allows them to present the same thermal energy.
With that we can conclude that the teapot received thermal energy from the stove and passed that energy to the tea that was inside it, in this way, tea and teapot had equal thermal energy. This tea, with high thermal energy, was placed in a cup with low thermal energy. The tea promoted a transfer of heat between him and the cup, allowing them to equalize their temperatures and consequently the thermal energy.
In this way, the cup has the same temperature as the tea, which has the same temperature as the teapot.
