Answer:
These species that are usually charismatic, attractive and attract people's attention.
Advantages of this type of conservation:
-These species make people aware of the importance of protecting and conserving these animals.
-It is an effective way to obtain financing for conservation projects.
- This conservation is positive because the conservation of Flagship species also means the protection of everything around them.
Disadvantages:
- If it is not carried out properly, it can become a tax eagerness forgetting the conservation goal.
-We run the risk of neglecting other organisms such as plants, since most of the flagship species are mammals.
In my opinion the advantages are more important than the advantages because the protection of these species will only be possible by taking care of all their ecological niche and that implies the conservation of several species and elements of the ecosystem such as water, air and forest.
Answer:
The microscopic structural unit of compact bone is called an osteon, or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella).
Explanation:
If there is no reason to change (constant climate), then change won't occur. For example, a desert is basically always dry and hot with sand and few clouds. If a creature is fit for the climate, it will continue to exist until a severe enough climate change. For a real world example, in pre-industrial Europe, the birch trees were white. This permitted white moths to survive and not get eaten by the owls that hunt them, until the industrial revolution. Ash got on the birch trees, changing the color of the trees to a darker black. The white moths stood out, and therefore got eaten, permitting the black variant of the moths to thrive, where they were close to complete eradication before the revolution.
The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
