(a)
Interpretation:
Physical property, ductile has to be classified whether it is for metallic elements or nonmetallic elements.
Concept Introduction:
Metals are elements that have characteristic properties of thermal conductivity, luster, electrical conductivity, and malleability. Except mercury, the physical state of all other metals is solids. They have very high melting points and high density.
Nonmetals are elements that are characterized by the absence of properties like thermal conductivity, luster, electrical conductivity, and malleability. Mostly nonmetals are gases. Only bromine is present as liquid in room temperature. The density of nonmetals is low and they have lower melting points than metals.
In the periodic table, a total of 23 elements are nonmetals. The metallic property of the elements decreases as moving from left to right across the period in a periodic table. The elements that are present in right side of the periodic table are nonmetals.

Interpretation:
Physical property, low electrical conductivity has to be classified whether it is for metallic elements or nonmetallic elements.

- In Drosophila, an X linked recessive mutation, scalloped (sd), causes irregular wing margins. Diagram the F1 and F2 results if a (a) scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female (assume the female is homozygous). Compare these results to what you would find if the trait was not sex linked.arrow_forwardCase Study—Ella Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.

Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues.

You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?
