Answer:
Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.
Explanation:
Mesopotamia ( Western Asia )was the first place of domestication of wheat. The favourable climate of intense sunshine of old Western Asia-kuwait, Iraq,...) favours photosynthesis which ensure food production,
Besides the population of this region with wide grains, on hilly land, ensured cross pollination of these wide seeds grains with wheat varieties leading to hybridization, and selection by natural selection for domestication and eventual evolution.
Reduces the visual acuity or sharpness
Alcohol, or any other drug which reduces the supply of oxygen in the bloodstream, can impair the sensitivity of the cones which, in turn Reduces the visual acuity or sharpness.
Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution
