An electric clothes dryer draws 20 A of current from a 240-V wall outlet. How much power, in watts, does it use?
TEA [102]

An electric clothes dryer that draws 20 amps of current from a 240-volt wall outlet will use 4800 watts of power.

The equation is P(W) = I(A) × V<span>(V)</span>

<span>P(W)= amp x voltage</span>

<span>20 amps x 240 volts = 4800 watts.</span>

Neurospora crassa was one of the first eukaryotic microbes to be adopted by geneticists as a model organism. It is a haploid fun
Anna007 [38]

Answer:

A) They have low-maintenance and are easy to keep track of for mutations.

B) The deduction can be "Single Gene Mutation"

Explanation:

After examining the example given in the question on Neurospora crassa and the details about how they reproduce, the following points can be made regarding the questions;

A) It is stated that they form a colony in time and that they are asexual spores and the first reason to choose them would be because they contain somatic cells (which refer to the cells other than reproductive cells) and non-motile gonidia which can multiply by dividing themselves and these properties make the colony's maintenance easy. And since they multiply by division, it is easier to keep track of the occuring mutations.

B) Given the information in the question that the mating is between an albino strain and a wild type, and then between two albino strains which have the same genotype. The results indicate that the strains have gone through single gene mutation during the process.

I hope this answer helps.

If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp, what result would you p
AnnyKZ [126]

If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.

<h3>What is proton gradient ?</h3>

Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).

For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.

Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.

Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.
