Explanation:
1. Since the Lions are the predator and Gazelles are the prey therefore a predator-prey relationship exists between them. The predator-prey relation is also associated with the food chain in an ecosystem. If the number of prey is reduced then there are chances that the number of a predator will also be reduced but
2. The Lion is not just the predator of Gazelle but other animals also like deer therefore they can shift their resource of food from gazelles to another organism.
3.The change of the ecosystem will change the population of the predator as the population are adapted to grow in a particular ecosystem and change of population could reduce the population of a predator.
The right answer is a.anatomy involves symmetry.
In the anatomy of multicellular animals with bilateral symmetry (which form the subregion of bilateria), there are many even organs, that is to say composed of two symmetrical halves, generally positioned on both sides of the median plane. This is the case, for example the human brain that includes two hemispheres, two amygdalas and two hyppocampus, a left and a right.
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
Answer:
the axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum. The appendicular skeleton is made up of all bones of the upper and lower limbs.
Explanation: i really hope that helps sorry if it did not.
Answer:
This nucleus then acquires <u><em>one </em></u>electron to become electrically neutral.
Explanation:
Fusion :It is nuclear reaction which two or more than smaller nuclei combines together to form heavy nuclear.
A neutron combines with proton in order to make heavy electron that is fusion reaction is taking place.

The overall charge in the nucleus will be +1.And in order to neutralize this positive charge the nucleus will acquire single electron to become electrically neutral.
