3. What is the difference between saponifiable and nonsaponifiable lipids?
Answer:
the difference is that unsaponifiable lipids do not contain fatty acids at least not as a component of the fundamental structure whereas saponifiable lipids do have fatty acids.
Explanation:
As a further explanation unsaponifiable lipids are lipids that do not contain fatty acids as components of the fundamental structure. On the other hand, complex also known as saponifiable lipids do contain fatty acids, and those fatty acids can be released in a process called saponification which is caused by alkaline hydrolysis.
How many units of energy would there need to be in the first trophic level to end up with 1000 units of energy in the second? in the third? in the fourth?
Answer:
(First) 10,000--->1000--->100-->10 (fourth)
Explanation:
Each trophic levels gets reduced by factor of 10.
Thus if you start with 10,000 in first, then you end with 1000 in second, 100 in third and 10 in forth.

Describe the relationship between the mass and metabolic rate of whales and seals in the Antarctic habitat. Explain why less massive species tend to require more energy to survive.
Organisms that have a higher metabolic rate due to large mass and hence require less energy
What is the relationship between metabolic rate and mass?We know that metabolic rate at which individual species carry out the process of metabolism.
It should be know that larger organisms that have a higher metabolic rate due to large mass and hence require less energy since metabolism produces heat. This owed to the fact that large size implies greater metabolism. Therefore, less massive species tend to require more energy to survive.

How might an environment be affected if humans introduce a new type of plant to the environment? A. The plant may compete with other plants for light. B. The plant may become another food source for animals. C. The plant may be poisonous and harmful to animals. D. all of these
Answer:
D. all of these
Explanation:
The reason is because all of the above are TRUE.
A. The plant may compete with other plants for light.
It feels like Plants and Trees are just stuff growing, but they actually compete with other plants, some don't do that much, but some do that, so that new plant may do it to get more light and might put more shade on other plants, which is dangerous for other plants.
B. The plant may become another food source for animals.
This is pretty normal, I mean, the thing here is that any plant is vulnerable to being eaten by an animal.
C. The plant may be poisonous and harmful to animals.
Yeah, like in choice B, the same thing, the plants are always Vulnerable to be eaten by hungry animals, and if an animal eats it... then it might get a disease or might just die.
So if these are all correct, then the answer HAS to be D. All of these
Answer:
D. All of these

Identify the interaction used to describe each type of interdependence among organisms. having too many fish in a pond can limit the amount of food and space available. the cheetah population depends on the gazelle population for food.
The dependence of the cheetah population on the gazelle population for food shows a kind of interdependent interaction.
What are interdependent interactions?They are a form of interaction between two organisms in which the survival of one is dependent on the other.
If the organism whose existence is important to the existence of the other should go extinct, it will greatly affect the survival of the latter.
Aside from going extinct, the rise and fall of one of the organisms affect the other either positively or negatively as well.

The roof of an eco-house is covered with soil. Covering the roof with soil decreases the thermal conductivity of the roof. What are the two of the choices listed below are advantages of having a roof with a lower thermal conductivity?
1) Less energy is needed to heat the house.
2) The rate of energy transfer by conduction is greater.
3) The roof is a better insulator.
4) The roof is less likely to leak.
5) Weather will have a greater effect on the temperature of the house.
Answer:
To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms -- conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.
Most common insulation materials work by slowing conductive heat flow and convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must be in contact with an air space.
Answer:
Explanation:
A thick layer of material with a low thermal conductivity reduces the rate of heat transfer from the ceiling into the roof space.
