<span>Phylogenetic tree is a tree that shows the evolutionary relationships between several species or other entities that are believed to have a common ancestry. A phylogenetic tree is a form of a cladogram.
In addition, a phylogenetic tree serves to determine the minimum number of divisions necessary to obtain a specific cell or tissue. From here, you can study, for example, the mutations generated throughout the process.</span>
i dont know
dont listen to me
cant get out of this screen
just putting this to close window
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. An example of macroevolution is the evolution of a new species. ...
Answer:
The diversity-stability hypothesis
Explanation:
An hypothesis is defined as a set of idea,explanation or information that you test through study and experimentation. . A hypothesis is is broad and it is not just a random guessing but well planned theory.The stability-diversity hypothesis states that the broader a community the more okay and productive the community will be. This hypothesis drawn from a more stable and productive communities can use their resources at their disposal better and great use.
Stability as a product of variability relative to community abundance.
8. (F) Facilitated diffusion: For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins.
9. (S) Simple diffusion: While water molecules are polar, they are also very small. One fact not mentioned in the video is that some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size.
10. (S) Simple diffusion: Charged ions are traveling through a cell membrane with the concentration gradient.
11. (A) Active transport: Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells.
12.(F) Facilitated diffusion: At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell.
The above choices are made based on the basic definitions of active transport, facilitated diffusion and simple diffusion.
Active transport: The movement of the ions or molecules to a region having higher concentration across the membrane requiring the help of energy or enzymes is active transport.
Facilitated diffusion: This type of transport involves passive movement of the molecules or is a type of passive transport where the movement of the molecules takes place from higher to lower concentration region occurs with the aid of a carrier molecule such as a transport or carrier protein.
Simple diffusion: This process involves movement of ions or molecules from high concentration region to low concentration region through a semipermeable membrane.
