Answer:
Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking. (So, they are conveniently packaged for cell division, in which the chromosomes must move to both poles of the cell.)
Explanation:Otherwise it would be a mess as they get tightly packed
Answer:
hope this helps you :)
Explanation:
Typically, a baby is born with 46 chromosomes. Babies with Down syndrome have an extra copy of one of these chromosomes, chromosome 21. A medical term for having an extra copy of a chromosome is 'trisomy. ' Down syndrome is also referred to as Trisomy 21.
The rocks would be younger the closer you get to the ridge
The Mid-Atlantic ridge is a divergent tectonic boundary in the middle of Atlantic Ocean spanning north to south.
Explanation:
At a divergent boundary, a phenomenon called seafloor spreading occurs as new crust is formed along the ridge. New crust seems to 'spread' from the ridge. Therefore, the farther away from the ridge you get, the older the crust gets. This occurs because magma from the mantle rises to replace the void created by the tectonic plates moving away. The magma rises and cools creating a mountainous ridge long the boundary. Seafloor spreading, however, happens really slowly and the changes are only perceptible over 1000s and millions of years.

Answer: Matthias Schleiden and Theodor Schwann
Explanation:
Each time a new ATP is created, ATP synthase must process 5 protons.
<h3>Where is ATP synthase found and what does it do?</h3>
- ADP and phosphate are converted into ATP by the mitochondrial enzyme ATP synthase, which is located in the inner membrane.
- Protons are transported over a gradient created by electron transfer from the chemically positive to the negative side of the proton, which drives the flux of protons.
<h3>How does photosynthesis's ATP synthase function?</h3>
- The light-driven production of ATP is catalyzed by the chloroplast ATP synthase, which is activated in the light and deactivated in the dark by redox-modulation via the thioredoxin system.
- This down-regulation is thought to be crucial for minimizing wasted ATP hydrolysis at night.
<h3>What makes ATP synthase so crucial?</h3>
All cellular functions are powered by ATP, which is constantly used by cells and required for production. About 100 ATP molecules can be produced by each ATP synthase every second.
