Answer:
yes
Explanation:
Due to polition I will see changes for example : Coral reefs dispearing and tectonic plates revealing what they hide.
The population of producers would get larger as nothing would be eating them anymore.
Answer:
O oceans, soils and forests
Explanation:
A carbon sink absorbs carbon from the environment. They do not release carbon to the environment.
The atmosphere is a good carbon source since it contains a significant amount of carbon dioxide gas.
- Carbon is found in the ocean in dissolved form.
- Soils are also good carbon sinks.
- Forest trees use carbon for their life processes
- One very integral process where carbon is used up is at photosynthesis.
- The carbon is used to make food materials.
A cell membrane is semi-permeable. This means that it is size-specific. It allows only a particular maximum size of particles to pass through it. Large molecules such as plasma proteins and lipid molecules cannot therefore penetrate while small moecules such as glucose will easily diffuse across it.
Secondly, a cell membrane is charged. The charge is as a result of a difference in ionization between the intracellular fluid and the extracellular fluid. Substances that have the same charge as the fluid into which they are diffusing will be hard to asorb due to repulsion effect. On the other hand, substances that have opposite charge as the fluid into which they are diffusing will be absorbed easily and faster.
Finally, the cell membrane is made of two layers. Lipid layer and phospholipid layer. Inside these layers, there are embedded particles and substances such as enzymes, receptors, hormones and ion channels. During diffusion of substances across cell membrane, some substances are speeded up by these substances. For instance, Translocase enzyme in the membrane of mitochondria speeds up the transfer of Carnitine transferase into the mitochondrial matrix.
The most common cause of anemia is iron deficiency.
