It is an example of Ex situ conservation. The correct option is A.
<h3>What is ex-situ conservation?</h3>
It is a method of conserving biodiversities outside their natural habitats.
Ex situ conservation is in direct contrast to in situ conservation. This means that in in-situ conservation, biodiversities are conserved in their natural habitats.
In the illustration, the Addax were released into fenced sections of protected areas in two countries.
The fenced section means that the Addax were not allowed to roam freely as they would in their natural habitats. The fenced section means that their movement is limited as compared to natural habitats.
Thus, the Addax were being conserved ex-situ.

Answer:
Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:
- Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
- Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.
Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.
Na is a neutral form of the sodium atom. Na+ on the other hand has a positive charge of 1. This + means that the atom has lost 1 electron, making it's charge more positive that it was before.it is a positive ion
The answer is Protons so its obviously A. You should go back on your textbook pages and look through the chapter.
