What is meant by the following statement about the cell membrane? The cell membrane is said to be semipermeable.
The cell membrane or a plasma membrane is a semipermeable membrane which means that this is a layer that allows only certain molecules that can pass through it. This allows the cells to keep their materials and the contents parted from the environment and from the other cells. This also makes the phospholipid bilayer an outstanding semipermeable membrane and protects the intracellular organelles from the environment that is outside from the cell.

Melanin is a type of pigment that make our hairs coloured. When ages past, this pigment is produced in minor quantities, that's why we lost that natural colour in our hair.
Eutrophication how can aquatic ecosystems change over time pogil answers
Eutrophication is a process in which a body of water becomes heavily enriched with nutrients, leading to excessive growth of plants and algae. Over time, this can lead to severe changes in the ecosystem, including hypoxia or anoxia. Human activities often drive this process.
Explanation:Eutrophication is a process in the world of aquatic ecosystems where a body of water becomes enriched in dissolved nutrients (such as phosphates) that stimulate the growth of aquatic plant life, usually resulting in the depletion of dissolved oxygen levels. This nutrient enrichment can cause a rapid increase in the growth of plants and algae (known as an algal bloom), blocking sunlight, and eventually leading to the death and decay of other organisms due to the lack of oxygen.
Over time, affected ecosystems may change drastically. In severe cases, this can lead to phenomena such as hypoxia (low oxygen) or anoxia (no oxygen), leading to widespread death of fish and other aquatic animals. It's important to note that this process is often driven by human activities such as farming, sewage discharge, and urban runoff.

How does andrew knoll's idea that "prokaryotic metabolisms form the fundamental ecological circuitry of life; bacteria, not mammals, underpin the efficient and long-term functioning of the biosphere" relate to the nitrogen cycle?
Andrew Knoll's idea about prokaryotic metabolism is related to the nitrogen cycle since some bacteria are responsible for this mechanism.
Some prokaryotic microorganisms are capable of using atmospheric nitrogen, in a process called biological nitrogen fixation in which N2 is converted to NH3 (ammonia).
Bacteria capable of carrying out this process encode a complex enzyme called nitrogenase, which is responsible for carrying out the fixation process.
The nitrogen cycle is the biogeochemical cycle on which the biosphere and all organisms depend for growth.
Nitrogen, being the most abundant element in the atmosphere, cannot be used by plants, however these bacteria can use it, and by associating with plants, they take advantage of nitrogen.
At this point, animals use plants as a source of nitrogen molecules, which does not require symbiotic relationships with fixing bacteria.
Therefore, we can conclude the nitrogen cycle is a vital circuit for the existence of life and it reaches us through a long chain of transmission, where prokaryotic microorganisms are a fundamental part of this cycle.
