A skeleton muscle is a composition of several components bundled one into the other.
Ivan

Answer:

An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Is a cells main function is to produce proteins to be excreted, such as on the pancreas, which organelles would you expect to be
nevsk [136]
Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.

Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) se
VikaD [51]

Answer:

The reflex arc follows this sequence of events

1. sensory receptor activation

2. sensory neuron activation

3.information processing

4. motor neuron activation

5. effector response

Explanation:

Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.

Can someone please help me with question 1
marshall27 [118]
Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.

Enough of my sentiments; I'm here to help, :-).

This answer is dependent upon what ecosystem you choose your project over.

So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.

For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.

Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
