Answer:
A) incandescent ligth bulb, its efficiency is about 10%
Explanation:
The incandescent bulb, that is, the well-known focus with its warm light, was one of the most useful inventions of the 19th century although its use is currently considered very inefficient. These lamps waste between 80 and 90 percent of the total electricity they consume by turning it into heat. The metal filament thus heated and which is the central part of the bulb, only converts the remaining energy into light. Its service life ranges from 750 to 1,000 hours.
This is why they are used in ovens for food preparation, because of the large amount of heat they generate.
The steam boiler in a power plant depends on the fuel that it is using, but a coal-fired power plant with modern technology its efficiency is about 40%
Electric motor are around 85-92%
In order to better understand the concept of efficiency it is as if we pay 100 dollars of gasoline for our weekly use, but of that 100 dollars the car only uses 10 dollars to do that activity the rest of the money the 90 dollars were lost because of the inefficiencies of the vehicle.
Answer:
sulcus
Explanation:
A sulcus is an indentation or depression in the brain that causes it to look like it ridges or folds
Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres.
Sulci can be basically can be divided into three basic function
limiting sulcus: This happens to develop between areas differing in structure and function, for example central sulcus
axial sulcus: This develops along the axis of a rapidly growing/developing area (e.g. calcarine sulcus)
operculated sulcus: a sulcus may be between two structurally-different areas and a third sulcus may lie in its wall and does not appear on the surface (e.g. lunate sulcus)
Answer:
D. 0.7 would be wild-type healthy
E. 0.3 would be affected Gg
Explanation:
Using the Punnett square we cross an homozygous male (gg), that is always healthy vs an heterozygous female (Gg). The result is 2 gg individuals, and 2 Gg individuals. Both gg individuals are healthy.
In a population of 1000 Gg individuals, 600 show the Gumball phenotype (unhealthy). It means that from the two heterozygous Gg (from the Punnett square), 1.2 show the unhealthy phenotype.
Again, from the Punnett square we have 4 individuals, that represent the 100%. 1.2 are unhealthy Gg, and represent 30% in F1.
This 30%, is equivalent to 0.3, that is the option E.
100 - 30 % = 70 %. This is 0.7 for healthy wild-type, option D.
