Describe how bacteria maintain its nature's balance.
Answer: Bacteria and fungi employ a variety of mechanisms to increase soil organic matter and function, but they do so at the expense of maintaining a healthy population in the soil. Bacteria contribute to ecosystem health by decomposing dead matter and cycling nutrients into useable forms. Bacteria may be found in all habitats and produce the majority of the oxygen on the planet. Bacteria are decomposers in the soil that break down organic compounds.
Explanation: I hope this helps, friend :)
They break down toxins, manufacture some vitamins and essential amino acids, and form a barrier against invaders

Anthony returns home from work. When he opens the front door of his house, he detects a strong smell of gas. He suspects that his gas pipe is leaking. Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of
Given what we know, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.
What is sensation?The sensation is a process that activates for each of the 5 senses. In this process, sensory neurons receive a stimulus and activate, sending a neural impulse to the brain with the information gathered. This information resulted in the ability to identify the smell as gas.
Therefore, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.

Which scenario is an example of the transfer of thermal energy by conduction? A. Hot air circulates in an oven. . B. Hot water heats up the cup that it is in. C. The air in a hot-air balloon is heated by a gas burner. D. You warm your feet in front of a fireplace.
Answer:
c.the air in a hot air balloon is heated by a gas burner.
The air in a hot-air balloon is heated by a gas burner - this is an example of the transfer of thermal energy by conduction.
What is thermal conduction?Thermal Energy is energy resulting from the motion of particles.
The process by which heat is transferred from the hotter end to the colder end of object is known as conduction. Thermal conduction is the diffusion of thermal energy (heat) within one material or between materials in contact.
In gases, conduction is due to the collisions and diffusion of molecules during their random motion. Photons in this context do not collide with one another, and so heat transport by electromagnetic radiation is conceptually distinct from heat conduction by microscopic diffusion and collisions of material particles and phonons. But the distinction is often not easily observed unless the material is semi-transparent.
The correct answer is option C.
