Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.
Answer: The correct sequence according to the question is steps- 4→1→3→5→6→2→7. Explanation: The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as …Read More »

The function h(x) = x2 + 14x + 41 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points) Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points) Part C: Determine the axis of symmetry for h(x). (2 points)
Answered by answersmine AT 22/10/2019 – 03:50 AM Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;x^2+14x+41=0x^2+14x=-41but;c=(b/2)^2and b=14hence;c=(14/2)^2=49substituting the value of c in the expression we get:x^2+14x+49=-41+49x^2+14x+49=8(x+7)^2=8this can be written in vertex form;h(x)=a(x-h)^2+kwhere:(h,k) is the vertex;thus(x+7)^2=8h(x)=(x+7)^2-8hence the vertex will be at the point:(-7,-8) Post your answerRead More »

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage. Which type of mutation causes sickle cell anemia? A)silent B)missense C)insertion D)frameshift
The right option is; B)missense Missense mutation is the type of mutation that causes sickle cell anemia A missense mutation is a type of nonsynonymous substitution in which the change of a single nucleotide (base pair) influences the genetic code and results in a codon that code for a different …Read More »
