separation of two ends of an old cell- cytokinesis
union of egg and sperm- fertilization
egg-producing organ in lower plants- archegonium
Answer:
in my oppinion its call a
source of pergisol
Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.
Photosynthesis and respiration are the opposite processes, basically speaking. Photosynthesis gets its name from light-dependent reactions, which involve photolysis of water (breakdown of H2O into oxygen and hydrogen), and then combining hydrogen with small sugar molecules, while also incorporating CO2 into them.
Answer:
The protein would contain threonine instead of proline
Explanation:
The rate of diffusion increases as temperature increases.Hence, the rate of diffusion will be the greatest in boiling water then warm water and cold water at last
- The movement of molecules along a concentration gradient is known as diffusion.
- It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
- Increased energy from higher temperatures causes the molecules to move more quickly, speeding up the diffusion process.
- Lower temperatures cause the molecules' energy to drop, which lowers the diffusion rate.
- The rate of diffusion increases with increasing concentration differences.
- The particles will move and mix more quickly at a greater temperature because they will have more kinetic energy.
Hence, the diffusion rate will be boiling water>warm water>cold water
