10. Why do different trophic levels have different amounts of energy?

Answers

Answer 1

Answer:

1. 3

2. insects

3. plants

4. snakes the 4th

5. birds

6.plant, bird, insect, snake

7. birds

8. Decomposers are organisms (bacteria and fungi) that break down dead organisms. They could be at all trophic levels

9. pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms.

10. energy is lost at each level. Most of the energy lost is lost as heat. Food webs and food chains both involve multiple trophic levels.

What are three ways energy is used by the organisms?

Answers

Answer:

Organisms use energy to survive, grow, respond to stimuli, reproduce

Explanation:

Three ways energy is used by the organism are food, nutrients, and sunlight.

What are living organisms?

Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.

Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.

Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.

Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

-Calculate the fluid pressure at Piston A.
-Calculate the force exerted on Piston B.
-Which principle is being applied? What does the principle state?
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

They can store water for a really long time because of the little rain.

Succulent plants have an adaptation that would help them survive in the desert.

Succulent plants

Cactus is an example of succulent plants that are adapted to survive in the hot and humid conditions of the desert. To survive in the desert, cactus has the following adaptations:

A modified flat green stem - helps in preparing food by photosynthesis and conserves water.The stem is covered with a thick waxy layer - helps to retain water.Leaves are present in the form of spines - prevent water loss through transpiration.Long roots -very deep into the soil for absorbing water.

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:

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.

C. Guanine

Explanation:

A pairs together with T, or U in RNA,

and C and G always pair together.

Answer:

The answer is C. Guanine

Explanation:

Pyrimidines always bond with purines. Since Cytosine is a pyrimidine, it must bind with a purine, which can either be Adenine or Guanine. However, Adenine has only 2 places for hydrogen bonding while Guanine has 3. Since Cytosine also has 3, it would bind to Guanine. GCAT is a useful acronym for remembering which binds to which.

A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?

Answers

Answer:

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Explanation:

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily
