There are two main types of light microscopes: COMPOUND and STEREO microscopes. COMPOUND MICROSCOPES are so called because they are designed with a compound lens system. The objective lens provides the primary magnification which is compounded (multiplied) by the ocular lens (eyepiece).
The best answer to describe an induced-fit model of an enzyme is option B. For this model, once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accommodate the product. It is a proposed mechanism of interaction between an enzyme and a substrate.
Answer:
Most of the training of animals is learned from <u>conditioned response</u>.
Explanation:
A conditioned response is a learned response to a previously neutral stimulus. This is achieved by pairing a neutral stimulus with an unconditioned stimulus, which doesn't require any conditioning to cause a reaction.
For example, the smell of food is an unconditioned stimulus that causes the feeling of hunger. This type of response to food is an unconditioned response. If we paired another stimulus, for example, the sound of a whistle, with the smell of food, this stimulus on its own would eventually start causing hunger. This makes the sound of the whistle the conditioned stimulus and feeling hungry after hearing the sound of the whistle the conditioned response.
Most of the animal training is based on this principle.
Answer:
Resistance in insects develops when the same insecticide (or class of insecticides) is used against a pest population over and over again. Some insects will survive the same dose that kills their friends. Those that survive pass on that survival trait to their offspring.

Here we will discuss Damage to infrastructure in the 2010 Haiti earthquake.
Toussaint Louverture International Airport:
If we talk about the focus point of the Haiti earthquake that hit the Haiti on 12th january, 2010, then it was around 6 miles away from Toussaint Louverture International Airport.
Since the center was so near to airport that is why airport suffered from alot of damage. The control tower of the airport was almost completely destroyed due to which any radio communication became impossible. There was heavy power outrage due to damage caused to the power lines and due to this lightening system of the airport was completely shutdown. was damaged. However, the taxiways, runways and apron parts of the airport were operational at even that time of crisis.
Due to immense amount of damaged caused to Toussaint Louverture International Airport, all the relief bringing planes were diverted to other airports of the city.
The reconstruction and rehabilitation of the airport was started during 2010. It included the restoration and renovation of arrival and departure halls that were previously completely devastated. The renovation os falls included installation 16 new stations and three large baggage carousels and in the immigration room, There was also a significant explansion in the custom rooms.
However, the damage caused to Toussaint Louverture International Airport dur to 2010 Haiti earthquake is still considered as the destruction of major landmark due to earthquake.
Hope it helps!
