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.
Anaerobic means with out oxygen
Answer:
Their nephron loop is closely wrapped with vasa recta.
Explanation:
Cortical nephrons are located in the cortex.
They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
Indicator species may provide useful substitute for large scale surveys to monitor biodiversity. Weconducted surveys in the Afro-alpine habitats of the Bale Mountains National Park (BMNP) with theobjective of identifying indicators for the species richness of the raptor guild. Raptors were countedby scan sampling technique from a suitable vintage point. Three classes of 18 sample units groupedaccording to the variability of the moorland ecosystem in the magnitude of process variables importantfor raptor species richness were used in determining the indicator value of species as a function of their abundance concentration and the percentage of species occurrence per sample group. Thisprocedure determined indicator values for all species in the resident raptor community. Comparisonwith randomly expected values demonstrated that only<span> Aquila verreauxii</span>and<span> A. chrysaetos</span>haveindicator values that were significantly larger than the randomly expected values. The species richnessestimated using the abundances of these two species predicted the observed species richness of thewhole community in a linear regression model that explained 66% of the deviance in the data set.Furthermore, the species richness of the community predicted by process variables had correlation of very high significance with that predicted by the indicator species. We have thus identified twoindicator species to a raptor guild of the BMNP and demonstrated that these two species encapsulatedmost of the information regarding the species richness response of the guild to key process variablesin the Afro-alpine moorland ecosystem. Our findings contribute significantly to current and futureefforts of monitoring the biodiversity of the park providing a cheap and quick means of data generation<span>relevant for making management decisions. Hope this helped! :)</span>
