Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = 
= -0.25
a = -0.25 m/
The deceleration of the plane is 0.25 m/.
Answer:
The correct answer is the option - mating factor.
Explanation:
Yeast can reproduce sexually by a signaling pathway called the mating factor pathway. Mating in yeast occurs between two haploid yeast cells. In this process, two yeast cells form a diploid cell.
In this process yeast cells secrete a signaling molecule termed as the mating factor that is used to attract them to mating cells to form a diploid cell.
Thus, the correct answer is option - mating factor.
The answer is A because the males sperm determines the sex of a baby.The determines sperm is carrying an X or Y chromosome.
Energy loss is demonstrated more clearly on an energy pyramid than on a food web.
Answer:
ADD and are organic compounds
Explanation:
Lipids that contain an ester functional group are hydrolysable in water. These include neutral fats, waxes, phospholipids, and glycolipids. Fats and oils are composed of triglycerides, made up of glycerol (1,2,3-trihydroxypropane) and 3 fatty acids to form a triester.
