Answer:
It is expected that 25% of the offspring are silver blue.
Explanation:
As was shown in the question above, in a population, the brown color is dominant, while the silver blue color is recessive. Thus, the brown color can be observed in dominant homozygous (AA) or heterozygous (Aa) organisms, since the dominant allele inhibits the expression of the recessive allele. However, the silvery blue color is only observed in homozygous recessive organisms (aa), since the recessive allele is only expressed in the presence of another recessive allele.
In the figure attached below, we can see that if a heterozygous brown organism (Aa) crosses with a silvery blue individual (aa), the offspring will be composed of 50% brown individuals (Aa) and 50% silvery blue individuals.

Not sure but the sentence is super understamdable
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.
Answer:
Angiotensin II atrial natriuretic peptide(ANP) lowers blood pressure.
Explanation:
Increase in plasma volume leads to increase in blood pressure and a decrease in plasma level also leads to a decrease in the blood pressure. ANP is an enzyme which stimulates the decrease in blood levels through certain factors thereby causing a decrease in the blood pressure.
Meanwhile ADH stimulates increase in blood plasma levels thereby increasing the blood pressure.
