A derived trait is a trait that the current organism has, but the previous one did not have.An ancestral trait is a trait that you, and your ancestors had.A vestigial structure is a structure that had some sort of use in your ancestor, but none in your current body
Answer:
This question is incomplete
Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.
Supine hypotension syndrome is the medical term for when a pregnant woman feels lightheaded and has a dip in blood pressure while lying down.
Supine hypotension in pregnancy: what is it?
- When you're pregnant, resting flat on your back might make some symptoms, including indigestion and shortness of breath, worse. Her blood pressure may also drop as a result of it.
- Supine hypotension syndrome is the medical term for when her blood pressure drops while she is pregnant and laying on her back. When a pregnant woman lies supine, the gravid uterus pushes on the inferior vena cava, resulting in a reduction in central venous return. This condition is known as a supine hypotensive syndrome (also known as inferior vena cava compression syndrome).
