D. single- and simple multi-celled organisms
Although more complex animals like invertebrates and multi-celled organisms began to appear, it was very late compared to the original, simpler organisms for which the Precambrian time is characterized by.
Answer:
So the wavelength of light is 1015.7 nm
Explanation:
From Wein's displacement law, we can write the following formula;
here,
is the wavelength of maximum radiation in meters
T is the absolute temperature (in Kelvin) for maximum radiation
K is the constant has a value of 
Given here, T = 2853 K
And we need to find 
Putting the values in formula



Answer:
-1/5
Explanation:
It is an established mathematical proof that the slope of line A perpendicular to another line B is the recoprovaknofokad
Hence the slope of B = the negative reciprocal of B
Given that ; lines s and t are perpendicular ;
Slope of S = 5 ;
The slope of T = - 1/5
