<h2>Answer:</h2>
Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.
<h3>Explanation:</h3>
- Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
- This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
- This bacterium is a soil bacterium which has no side effects on humans.
- Due to use of this technology, the poisonous chemical insecticides are not used in crop production.

All neurotransmitter receptors should be thought of as having two functions: First, to detect a particular neurotransmitter, and second, to do something<span> when they detect it. The receptor determines what the neurotransmitter's effect is. So it's not always right to call a neurotransmitter inhibitory or excitatory. Glutamate, for example, is among the most common neurotransmitters, and it's almost always excitatory... Except when it binds to a particular type of glutamate receptor, which is inhibitory. Done dopamine receptors are excitatory, some are inhibitory, and not all receptors have effects that fit neatly into those two categories. Sometimes a receptor will have an effect on something completely different... When the NMDA subtype of glutamate receptor is activated, for example, it can cause the postsynaptic cell to change what receptors it puts at that synapse (a cell can have different receptors at different synapses!). Your welcome!

The two types would be thermal energy and light radiation, which is usually present in most ecosystems since the sun gives off both of them.
<u>Answer</u>: Infundibulum, ampulla, isthmus, uterus.
<u>Explanation</u>:
- The ovary produces the egg and, it releases one unfertilized egg every month.
- The egg then travels through the fallopian tube to the uterus.
- The fallopian tube consists of three parts:
1. <em>Infundibulum</em>- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.
2. <em>Ampulla</em>- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.
3. <em>Isthmus</em>- it is also a ciliated region which controls the transport of both sperm and the embryo.
- Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.
- <em>So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.</em>
