<span>The phosphorus cycle is a biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus. Phosphorus mainly comes from soil and rock on the Earth and is recycled by living organisms</span>
The answer is <span>Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring.
Through the elimination process:
</span><span>* Fish are <u>invertebrates</u> and have scales and paired fins, while mammals are vertebrates and have fur or hair. - Fish are vertebrates!
</span><span>* Fish are <u>endothermic</u> and have gills, while mammals are <u>ectothermic</u> and have lungs. - Fish are ectothermic (cold-blooded), and mammals are endothermic (warm-blooded)!
</span>* <span>Fish have streamlined bodies and <u>three-chambered hearts</u>, while mammals are <u>bipedal</u> and have four-chambered hearts. - Fish have four chambered hearts and not all mammals are bipedal!
This leaves choice: </span><span>Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring. All of this is true, but it should be taken into consideration that some fish give live birth and some mammals lay eggs, but this is the most possible choice among all mentioned.</span>
Answer:
True
Explanation:
They are unbiased they have to consider everything before coming to a conclusion.
The tropomyosin filament would not be dislodged preventing contraction.
The cross bridges would remain linked and therefore contraction would stop
The cross bridges would break apart due to the presence of calcium ions enabling some contraction
The myosin heads would separate from the actin molecule due to the release of ADP that was previously present.
<span>1.ATP hydrolysis </span>
2.Detachment of myosin head from actin
3.Power stroke
<span>4.Crossbridge formation</span>
