Animal Rights Law and Politics: What change did the Sierra Club case bring to standing law?

Case: Sierra Club v. Morton, 405 U.S. 727 (1972)

2. Black bodies and vestigial wings in Drosophila are caused by recessive alleles on chromosome 2. A long-winged male with yellow-brown body color, homozygous for the wild-type alleles, b+b+ v+v+, was exposed to X-rays to induce mutations in germ-line cells (i.e. to generate mutations in the gametes the male produced). He was then mated to a homozygous recessive black-bodied, vestigial-winged female, bb vv. Among the offspring, a male with a black body and vestigial wings was observed.

a. What are the expected genotypes and phenotypes of the progeny of the cross given above?

b. Describe a chromosomal rearrangement that would explain the observed black-bodied, vestigial-winged male.

Tunapuna Technologies (TT) is a privately traded firm with a target debt to value (D/V) ratio of 15% and current interest rate on debt of 6%.

Since the firm is privately traded, you turn to Arima Technologies (AT), TT’s closest publicly traded competitor, for data to estimate TT’s WACC. AT has a beta of 1.5 and a debt-to-value (D/V) ratio of 35%.

The current risk-free rate is 3.5%, the expected market risk premium is 6.5% (Rm-Rf), and the corporate tax rate for both firms is 40%.

(a) What is the “best estimate” of the equity beta for TT?

(b) What is the required return on equity for TT?

(c) What is the WACC for TT?

1) Which of the following statements is (are) true?

I.An excited atom can return to its ground state by absorbing electromagnetic radiation.

II.The energy of an atom is increased when electromagnetic radiation is emitted from it.

III.The energy of electromagnetic radiation increases as its frequency increases.

IV.An electron in the n = 4 state in the hydrogen atom can go to the n = 2 state by emitting electromagnetic radiation at the appropriate frequency.

V.The frequency and wavelength of electromagnetic radiation are inversely proportional to each other.

A) II, III, IV

B) III, V

C) I, II, III

D) III, IV, V

E) I, II, IV

Two problems needed to be worked out below:

1. If natural gas (98 percent CH4 by weight) is used to fuel a power plant, compute (a) the amount of oxygen required (in ton/hr) to produce 100 MW of power and (b) the amount of CO2 emission. Assume the calorific value of gas is 50 MJ/kg and all the heating value of gas is converted to electricity power.

2. Determine the saturation concentration of O2 (in mg/L) in water at 10 oC at 1 atm. Will the saturation concentration higher or lower at 20 oC? Use the following assumptions:
O2 is 21% of air (v/v)
Henry’s constant of oxygen in water is 3.27 ´ 104atm.

Design a buck-boost converter with a source varying from 10 to 14 V. The output voltage is regulated at – 12 V. The load varies from 10 to 15 W. The output voltage ripple must be less than 1 % for any operating condition. a) Determine the range of the duty ratio of the switch. b) Design the inductor and capacitor values used in your design. c) Confirm your solutions using a simulation software for every operating condition (you must show the input voltage, the duty ratio, the output voltage “including the ripple” and the inductor current “including the ripple”). Already have sloution for part (a) and (b), need help with part (c).

1.Will magnesium metal displace Al3+ ion from an aqueous solution

Al³⁺(aq) + 3e^- --> Al(s) E^o=1.68 V

Mg²⁺(aq) + 2e^- --> Mg(s) E^o= -2.36 V

a) No, since E^o cell is positive.

b) Yes, since E^o cell is negavtive.

c) No, the reverse reaction is spontaneous

d) Yes, since ΔG^o is negavtive.

2.The value of K_p for the reaction at 298k.

2SO₂(g) + 2NO₂(g) --> 2SO₃(g) + 2NO(g)

is 0.25. The value of K_p at the same temperature for the reaction

SO₂(g) + NO₂(g) --> SO₃(g) + NO(g)

a) 0.25

b)0.063

c)0.12

d)0.50
