The brain and central nervous system shrink as we age.
<h3>What happens to the brain when we age?</h3>
The brain is one of the most important organs in our body because all the nerve signals are produced there for our body to function.
In the brain we find nerve connections through neurons. A particular aspect of them is that during childhood and adolescence they multiply as we learn new things.
However, once we reach the stage of old age, these nerve connections deteriorate and are reduced, therefore, the size of the brain and the central nervous system decreases.

Answer:A global warming
Explanation:because the adding of greenhouse gases to the atmosphere increases the warming up.
The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.
In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.
All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.
Mitosis is a four-stage process that creates two identical cells from one original cell. In Mitosis chromosome the cell divides intotwo identical sets daughter nuclei. in mitosis the mother cell divides into two daughter cells which are genetically identical toeach other and to the parent cell.Meiosis is a reduction cell division where the number of chromosomes is divided into half. In Meiosis it gametes formationsoccur in animal cell and meiosis is necessary for sexual reproduction. The meiosis has 6 phase: Meiosis I, Prophase I ,Metaphase<span>I, Anaphase I, Telophase I, Meiosis II</span>
Explanation:
it is the tendency relatively stable equilibrium between interdependent elements especially as maintained by physiological processes.
