Show all your work!

Answers

Answer:

80N

Explanation:

in both sides, pressure is the alwyays the same whatever the area is..

First we calculate the pressure at piston A:

P= F÷a

given that,

#F= 20N

#a=1m^2

P= 20÷1

P= 20 Pa.

At piston B:

pressure is the same = 20Pa

Area= 4m^2

P=F/a

F= P×a

F= 20 × 4

F= 80N

Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not react the same chemically. Which of the following generalizations can explain this? (5 points)
a
Monosaccharides serve different cellular functions, and they are only involved in reactions in which they are needed.

b
The atoms of monosaccharides are arranged differently, and the different shape gives each monosaccharide unique properties.

c
Monosaccharides have different properties, but the disaccharides they form when combined with other molecules will have the same properties.

d
The atoms of monosaccharides are arranged similarly, but the monomers from which they are formed have different physical and chemical properties.

Answers

Answer:

B

Explanation:

Monosaccharides are the simplest carbohydrates. Although glucose and fructose have the same molecular formula they have different structures or the atoms are arranged differently from each other and this is evident in the way they react, behave and in their properties.

Succession describes the sequential appearance and disappearance of species in a community over time after a severe disturbance. In primary succession, newly exposed or newly formed rock is colonized by living organisms; in secondary succession, a part of an ecosystem is disturbed and remnants of the previous community remain especially soil. In both cases, there is a sequential change in species until a more or less permanent community develops. What is the process of ECOLOGICAL SUCCESSION? *

Answers

Answer:

The answer will be listed below.

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less predictable changes following a disturbance or the initial colonization of a new habitat.
