<span>The anterior cingulate cortex is the part of the brain that has to do with the connection between thinking and emotions, when areas like these are overly stimulated by congenital disorders like anxiety disorders they may be treated by a partial destruction of this area which could lower the synaptical activity of this area.</span>
Answer and Explanation:
A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.
Answer:
the moon is one-fourth the size in earth diameter (write fraction in the blank.) the distance from the moon to the earth is 385,000 earth diameters. one of the limitations of this model is that it does not describe the movement of the earth and the moon in each of their orbits. complete the sentences below to add that information to the model it takes 27 days to orbit around the earth. the moon orbits earth in a Circle
Answer: (d) e^12
Explanation:
<em>The relationship between the standard free energy change, </em>ΔG, and the equilibrium constant, K at a particular temperature is represented<em> Using the formula</em> ΔG = -RTlnK, where G = -30, RT = -2.5 and [Pi] = 1
lnK = ΔG/-RT
lnK = -30/-2.5
lnK = 12
<em>taking exponents of both sides</em>
e^(lnK) = e^12
K = e^12
The answer here is Prophase 1 (A)
In the event of meiosis, Prophase 1 occurs right after Interphase (stage when DNA is replicated). In the Prophase 1 stage, chromosomes condense and pair off and then exchange DNA between each other in a manner of crossing-over homologous chromosomes. The cross-over procedure forms a X-like region called Chiasmata that holds the homologous chromosomes intact.
