Hi dude I might be wrong but i'm 100% thinking it is A)Truck 1 carries oxygen and Truck 2 carries carbon dioxide. The reason I say this is because the heart and lungs have two main systems known as respiratory system and circulatory system that take carbon dioxide and replaces it with oxygen, which it takes to the brain so you body can function. Hope this helps sorry it so lately answered.

kifflom [539]

Answer:

Binding of   <u>ACh (acetylcholine)  </u>  to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Hence , the answer is  <u>ACh (acetylcholine) .</u>

What is an example of a biotic factor in a biome?: * A. scavengers B. producers C. soil
charle [14.2K]

Answer:

The correct answer is A. scavengers and B. producers

Explanation:

Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.

So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.  

So both scavengers and producers are living organisms therefore both are examples of biotic factors.
