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.

things build using nitrogen?
select all that apply.
a
protein
b
carbohydrates
c
lipids
d
nucleic acids
Nitrogen is an essential component for living cells, as it is involved in synthesis of amino acids and nucleic acids. These amino acids polymerize to form proteins. So the organic macromolecules do living things build using nitrogen is protein and nucleic acids, i.e., option a and d.
What are amino acids?Amino acids are the smallest unit or one can say building block of protein.
It usually have an amino group and a carboxyl group and a side chain. It is linked together by peptide bonds.
As it has an amino group, it requires nitrogen for its formation, and it will ultimately form protein.
Nitrogen is also required for the formation of nucleic acids i.e., DNA and RNA.

The Split-brain theory describes the differences between left brain and right brain characteristics, functions, and understand the dominance brain.
What is split-brain theory?The split-brain phenomenon is caused by the surgical severing of the corpus callosum, the main route of communication between the cerebral hemispheres. The classical view of this syndrome asserts that conscious unity is abolished
The left brain handles reading, writing, and calculations. Some call it the logical side of the brain whereas The right brain is more visual and deals in images more than words. It processes information in an intuitive and simultaneous manner.
The left hemisphere controls the muscles on the right side of the body while the right hemisphere controls those on the left.

olfactory cells and taste buds are normally stimulated by ________.
Answer:
The answer is substances in solution.
Explanation:
Olfactory cells and taste buds are normally stimulated by substances in solution.
Olfactory cells are normally stimulated by odorants, which are chemical substances that are volatile and capable of being detected by the sense of smell.
Taste buds, on the other hand, are normally stimulated by tastants, which are chemical compounds that can be tasted. Tastants include various molecules such as sweet, sour, bitter, salty, and umami compounds.
Both olfactory cells and taste buds play crucial roles in our perception of smell and taste, respectively, and they are stimulated by specific chemical substances that interact with receptors present in these sensory cells

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.

Answer:
------->
Explanation: Why worker egg-laying occurs in honey bee colonies. Usually, colony behavior, egg-laying, and ovary development in worker honey bees are prevented by queen pheromones and open brood pheromones. However, in the absence of these regulating pheromones, workers may develop ovaries that will enable them to lay their own eggs.
