Answer:
c. macula densa
Explanation:
The cells of the macula densa are sensitive to the concentration of sodium chloride in the distal convoluted tubule. They are a part of the nephron.
Answer:
Mars
Explanation:
The Deep Freeze: Ice on Mars. Like Earth, Mars has ice caps at its poles. Water reaches the poles as vapor and is frozen into thin layers that build up thick deposits. Mixed with this water is dust picked up by the wind, so the caps have bright and dark layers of "clean" and "dirty" ice.
Answer:
Movement.
Reproduction.
Respiration.
Responsiveness.
Excretion.
Adaptation.
All organisms have nucleic acid as the hereditary molecule.
All organisms show adaptation, which occurs at the individual level and is tightly related to homeostasis.
The answer is bacteria becauce bacterias are decomposers.
I hope this helped!!!:)
The skeletal muscle is one of the three types of muscle in the organism. <em>Option a) is correct. From smallest to largest, the parts of a </em><em>skeletal muscle </em><em>are Myofilament, sarcomere, myofibril, muscle fiber, fascicle, muscle. </em>
<h3>
The skeletal muscle</h3>
- It is the most abundant muscle in vertebrates, constituting the somatic musculature.
- Among its many functions, it proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It also participates in<em> eye movements, respiration, mastication, deglutition, and phonation</em>.
- The skeletal muscle contracts voluntarily, and its response is fast.
- Cells composing the striated muscle are significantly longer and multinucleated. They arrange in bundles, where cells are parallel to each other.
<h3>Composition of skeletal muscle</h3>
- <em>Myofilaments </em>⇒ Actine and miosine
- <em>Sarcomere</em> ⇒ It is the functional unit with the contractile apparatus. Composed of the Z band, A and I bands, and H zone.
- <em>Myofibrilles</em> ⇒ They have the Functional units
- <em>Muscle fibers</em> ⇒ Surrounded by endomysium
- <em>Fascicle </em>⇒ Group of fibers surrounded by perimysium.
- <em>Muscle</em> ⇒ Group of fascicles surrounded by epimysium.
Hence, the correct option is a).<em> From smallest to largest, the parts of a </em><em>skeletal muscle </em><em>are Myofilament, sarcomere, myofibril, muscle fiber, fascicle, muscle.</em>
