Cyanobacteria helped produce O2. Because it helped releasing O2 into the atmosphere, today we see different animals because Cyanobacteria helped reduce the poor oxygen in the atmosphere.
The polar climate zone includes the areas of Earth near the North and South poles. The northern polar zone includes parts of Canada , United Kingdom, and Russia . The southern polar zone includes Antartica .
It is important that the phospholipid bilayer is both hydrophobic in the surface and hydrophilic inside to control and manage the incoming organic compounds mainly water from exceeding the needed amount or destablizing the concentration established by the cells.
Hydrophilic is a characteristic of an object which is attracted to water or can synthesize with water. In contrast to hydrophobic like fats, oils and lipis which has a strong aversion and dislike to water molecules.
Transmembrane proteins are found in the plasma membrane. Hydrophilicregions are embedded within the membrane, and Hydrophobic regions project from both surfaces of the bilayer.
Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.
Yes, the pinch of the top of plant in growing time by cutting through apical meristem is helpful for creating the cells and it is also helpful for growth of plant and for the increase in the yield of garden.
Explanation:
Apical meristem is below the surface of the branches and also the roots. Some cells are divided through this process but some other cells are differentiated and divided into structural or vascular cells. There are mainly two types of apical meristems based on its location present in plant. The root apical meristem and shoot apical meristem.
Answer:
In the S Phase
Explanation:
This is because chromosome duplication occurs in this which is similar or the same to DNA synthesis
