Newton's third law of motion states that for every action there is an equal and opposite reaction. Science teachers often model this law by showing what happens when two floating balls collide in a pool of water. What is the most likely reason that science teachers explain this law by modeling it?
Answer:
The law is an abstract idea that may be difficult to understand without seeing how it works.

1. composition of outer covering
2. composition of genetic material
3. stages of reproduction
4. stages of life cycle
Answer:
the answer is 1
Explanation:
Viruses and cells are different in many ways but in composition of outer covering these ways they same to each other. Thus, option A is correct.
What are viruses?Viruses are defined as the microorganisms who needs to infect the living host cells, in order to replicate as well as reproduce. These infectious agents has been capable of the injecting as well as infecting all the life forms the present, including the plants, or the animals and bacteria.
The viruses were not just among the first organisms that has been evolve as in the order to replicate themselves and it will continue through the time they needed other organisms' cell. Aerobic bacteria has been the bacteria that has been need oxygen just perform cellular respiration, and that can survive and grow in the oxygenated environment, while anaerobic bacteria has been the bacteria that do not require oxygen for their growth.
Therefore, Viruses and cells are different in many ways but in composition of outer covering these ways they same to each other. Thus, option A is correct.

5. What is true about energy transfer in communities?
A. It is 100 percent efficient.
B. It moves from consumer to producer.
C. Most of the energy in a trophic level is lost as heat.
D. Most of the energy in a trophic level transfers to one above it.
Answer:
D
Explanation:
Most of the energy in a trophic level is lost as heat. Therefore, option C is correct.
How does energy transfer from one trophic level to another trophic level?As energy moves from the primary producers through the various trophic levels of consumers and decomposers, significant amounts of energy are lost from the ecosystem between one trophic level and the next level.
The second law of thermodynamics, which states that whenever energy is changed from one form to another, there is a tendency towards disorder (entropy) in the system, is the primary cause of this loss.
When the organisms from one trophic level are consumed by the next level, this means that a significant amount of energy is lost as metabolic heat in biological systems. Therefore, option C is correct.

How many water molecules are released in the synthesis of 10 maltose and 15 sucrose?
Answer:
10 water molecules are released in the synthesis of 10 maltose and 15 water molecules are released in the synthesis of 15 sucrose.
Explanation:
10 water molecules are released in the synthesis of 10 molecules of maltose and 15 water molecules are released in the synthesis of 15 molecules of sucrose because in a reaction, when two glucose molecules fuse together forming a molecule of maltose with the release of single water molecule while on the other hand, when glucose and fructose fuse together forming sucrose releases single molecule of water, so in each case, one molecule of water is produce.

A bird catches and tries to eat a caterpillar. The caterpillar has a bad taste, so the bird lets the caterpillar go. The next time it sees the same kind of caterpillar, the bird avoids eating it. Which best describes this behavior? trial-and-error learned behavior trial-and-error instinct behavior conditioned reflex behavior conditioned inherited behavior
Answer:
The correct option is trial and error learned behavior
Explanation:
A trial and error learned behavior is a type of behavior in which an organism attempts to or tries something new which makes it (the organism) accept the reality of that thing or situation. This means that if the attempt is successful or pleasurable, the organism will attempt it again and if it's not, the organism will avoid that thing.
This is what was described in the question with the bird trying to eat the caterpillar but found it unpleasurable which made it to start avoiding it afterwards.
Answer: A trial-and-error learned behavior

Solute particle Cell membrane
Which of the following describes the process?
a.
The model shows the process of active transport because the solute particles are
moving from an area of low concentration to an area of high concentration.
b.
The model shows the process of bulk transport because the solute particles are
moving from an area of low concentration to an area of high concentration.
C.
The model shows the process of diffusion because solute particles are moving from
an area of high concentration to an area of low concentration.
d.
The model shows the process of osmosis because the solute particles are moving
from an area of high concentration to an area of low concentration.
Answer:
C
Explanation:
Solute particles are constantly moving around in a solution, interacting with one another, and dispersing in different directions. Simple diffusion is the term used to describe the random mixing of solute particles in a solution. Thus, option C is correct.
What are the factors in solution for solute movement?Active transport is the term used to describe the movement of solute particles from low to high concentration.
Because they will have more kinetic energy. The rate of diffusion increases as surface area increases.
Particles of the solute move against the concentration gradient during active transport. Solute particles travel from a low-concentration region to a high-concentration region in this manner.
Therefore, model shows the process of diffusion because solute particles are moving from an area of high concentration to an area of low concentration.
