Negative ion <span>occurs when an atom gains an electron (negative charge) it will have more electrons than protons.</span>
Active transport requires that the cell move engegy that it has obtained the food to move the molecule threw the cell membrane.The passive transport doesn't required as much energy for the molecule to move....
Answer: 2-3
Explanation:
A biological neural network or neural circuit is a set of ordered synaptic connections that occur as a result of the binding of neurons to others in their corresponding regions following neural migration. At birth, a baby has an average of 100 billion neurons, but few neural connections. These will multiply as the child grows, through environmental, sensory, cognitive and movement stimulation. <u>Stimulating mobility and physical activity also has a positive effect on cognitive functioning by modifying the activity of certain brain areas</u>. Physical exercise has beneficial effects on brain function, such as promoting neuroplasticity and increasing learning and memory performance, which may be due to increased expression of various neural growth factors.
<u>Finally, environmental stimulation is basic for harmonious brain development and for laying the neurophysiological foundations of our children's future brains. </u>Thus, there are many mechanisms that nature has at its disposal to prevent babies from being left helpless. All of them favour their relationship with adults and thus their neurons, at a time of maximum growth of their extensions, can form the brain circuits that allow the acquisitions that make them advance in their neurodevelopment. If babies do not receive from their adults sufficient affection and attention, brain growth will be much less and their neurodevelopment will inevitably be delayed, because what makes the brain grow and change is precisely the creation of new circuits as it learns new things, and those who can learn most are the most experienced. By aboyt 2-3 months is when circuits of the brain begin to be created.
A virus is a microscopic parasite that infects cells in biological organisms, they reproduce only by invading and controlling other cells as they lack the cellular machinery for self reproduction. Additionally, viruses contain at least one unique protein synthesized by specific genes in the nucleic acid, the proteins forms a shell called capsid around the nuclei acid.
