H5N1 and SARS are examples of a. extinct species. b. forms of greenhouse gases. c. endangered habitats. d. emerging diseases.

Expert Solution

The answer is d, emerging diseases.

H5N1 is a strains of the influenza virus that primarily infect birds, but can also infect humans. This type of flu is most often contracted by contact with sick birds. It can also be passed from person to person. Symptoms begin within two to eight days and can seem like the common flu. Cough, fever, sore throat, muscle aches, headache and shortness of breath may occur. The disease can carry a high mortality in humans. Some antiviral drugs, if taken within two days of symptoms, may help.

SARS is contagious and sometimes fatal respiratory illness caused by a coronavirus. SARS appeared in 2002 in China. It spread worldwide within a few months, although it was quickly contained. SARS is a virus transmitted through droplets that enter the air when someone with the disease coughs, sneezes or talks. Fever, dry cough, headache, muscle aches and difficulty breathing are some of the symptoms. No treatment exists except supportive care.

research conservation efforts “Endangered species in Canda,” Are any species likely to be extinct within the next 50 years? Pick one conservation effort and evaluate published reports. Is it likely that the species will recover and what are the major obstacles to overcome in order to achieve species preservation? Provide suggestions for research to be conducted for better management, as well as changes to management to improve odds of recovery for the species.

Recently, the power of cloning to rescue endangered or extinct species was demonstrated by applying nuclear transfer methods to save the mouflon, a species of wild sheep (left half of figure). This result piqued a fair amount of general interest, because of its possible implications for the return of other, more exotic, species from the jaws of extinction (as pictured on the right). Suppose a wealthy investor came to you with a proposal to create a real-life Jurassic Park (naturally,...

Indicate how each of the 8 forms of species interaction exists in an ecosystem. Give examples of each type of interaction, and whom benefits or sacrifices. Include why this type of interaction stays prevalent in the population (ie: what is the payoff?).

Consider an ecological niche with three species A, B and C. Their dynamics are given by their population rates shown below dA/dt=A+B-C … (2a) dB/dt=-A+2B … (2b) dC/dt=C-A-B … (2c) Initially, the niche is in equilibrium with the population of C=30. Obtain the population densities of the rest of participants in the niche at its equilibrium. Starting from the point (A=8,B=4,C=10), obtain their individual populations over time t. What if the initial starting point is perturbed to (A=7,B=4,C=10)? Would the...

An area (A) occupied by a species splits into two areas (B and C). One of these areas (B) then splits into two areas (D and E). The other of the areas (C) splits into two areas (F and G); area F then splits into two areas (H and I), and area G then splits into two areas (J and K). Draw a series of maps that describe vicariance through time, labeling each of the areas by letter. Then draw...

Chemical species A, B, C, D and E are involved in a reaction. They may represent reactants, products, intermediates, catalysts or inhibitors. The rate of change in the concentration for each of them is given below: d[A]/dt = -k1[A][B] + k-1[C][B] + k2[C][D] - k-2[A][E] d[B]/dt = 0 d[C]/dt = k1[A][B] - k-1[C][B] - k2[C][D] + k-2[A][E] d[D]/dt = -k2[C][D] + k-2[A][E] d[E]/dt = k2[C][D] - k-2[A][E] a) Write down the elementary steps in the proposed reaction mechanism that are...
