Answer:

1. Prokaryotes do have their genomic DNA concentrated and localized to a small area within the cell (nucleoid region). So it's not entirely accurate to say that prokaryotes don't have a nucleus. The cell can release DNAses into the cytoplasm to degrade viral DNA, with reduced risk of degrading it's own DNA.

2. A bioengineer would use the principles of mass and heat transfer to address a problem in human healthy by using mass and heat to solve problems in human health.

3. The key areas of controversy related to genetically modified food (GM food or GMO food) are whether such food should be labeled, the role of government regulators, the objectivity of scientific research and publication, the effect of genetically modified crops on health and the environment,

4. Biomaterial is an important part of bioengineering is because it plays a critical role in medicine today to restore function and facilitate healing for people after injury. These may be natural or synthetic and are used in medical to support, enhance, or replace damaged tissue.

5. Ethical issues that arise from modern biotechnologies include the availability and use of privileged information, potential for ecological harm, access to new drugs and treatments, and the idea of interfering with nature. Applications include agriculture and health care.

hope this helps

have a good day :)

Consider the following chain-reaction mechanism for the high-temperatureformation of nitric oxide, i.e., the Zeldovich mechanism

vagabundo [1.1K]

Answer: hello attached below is the properly written chain reaction to your question

answer :

d[NO] / dt = $k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] + K_{3f}[N][OH]$

d[N] / dt = $k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] - K_{3f}[N][OH]$

Explanation:

<u>write out expressions for d[NO] / dt and d[N] / dt</u>

Given :

properly written chain reaction ( attached below)

Expression for d[NO] / dt can be written as

$k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] + K_{3f}[N][OH]$

Expression for d[N] / dt can be written as

$k_{1f} [O] [N_{2}] + K_{2f} [N][O_{2} ] - K_{3f}[N][OH]$

Cool water at 15°C is throttled from 5(atm) to 1(atm), as in a kitchen faucet. What is the temperature change of the water? What

Tresset [83]

Answer:

the lost work per kilogram of water for this everyday household happening = 0.413 kJ/kg

Explanation:

Given that:

Initial Temperature $T_1$ = 15°C

Initial Pressure $P_1$ = 5 atm

Final Pressure $P_2$ = 1 atm

Data obtain from steam tables of saturated water at 15°C are as follows:

Specific volume v = 1.001 cm³/gm

The change in temperature = 2°C

Specific heat of water = 4.19 J/gm.K

volume expansivity β = 1.5 × 10⁻⁴ K⁻¹

The expression to determine the change in temperature can be given as :

$\delta \ T = \frac{-V (1- \beta \ T}{C_p} * \delta \ P ( \frac{1}{9.87} \ \frac{J}{cm^3/atm})$ $\delta \ T = \frac{-1.001 \frac{cm^3}{gm} (1- 1.5*10^{-4} \ K^{-1} )*2}{4.19 \ \frac{J}{gm.K}} *(5-1)atm ( \frac{1}{9.87} \ \frac{J}{cm^3/atm})$

Δ T = 0.093 K

Now; we can calculate the lost work bt the formula:

$W_{lost} = T_{surr} *S$

where ;

$T_{surr}$ is the temperature of the surrounding. = 20°C = (20+273.15)K = 293.15 K

From above the change in entropy is:

$\delta \ S = C_p \ In (\frac{T+ \delta \ T }{T}) * \beta V \delta P$

$\delta \ S = 4.19* \ In (\frac{288.15+0.093 }{288.15}) - 1.5*10^{-4} * 1.001 (5-1)* (\frac{1}{9.87})$

$\delta \ S =1.408*10^{-3} \ J/gm.K$

$W_{lost} = T_{surr} *S$

$W_{lost} = 293.15* 1.408*10^{-3} \ J/gm.K$

$W_{lost} = 0.413 \ kJ/kg$

Thus, the lost work per kilogram of water for this everyday household happening = 0.413 kJ/kg

Explain working of Laser Doppler Vibrometer with diagram.

Klio2033 [76]

Answer:

A laser-Doppler vibrometer identifies the Doppler effect or shift of laser light reflected from the sample object

Explanation:

A laser-Doppler vibrometer (e.g. Micro Motion Analyzer 400 from Polytec) identifies the Doppler effect or shift of laser light reflected from the sample object .At a beam splitter, a laser beam is partitioned into a measuring beam and a reference beam that deflects 90 ° upwards and transmit to the reference mirror "RM." Both beams come back to the beam splitter.
