The species of bird with the greatest variation in traits
Answer:
cell transport or membrane transport helps in the transport of solute molecules and ion across the plasma membrane and helps in maintaining homeostasis of these molecules in the biological system.
Explanation:
Homeostasis is very very important to maintain a steady body physiology and the maintenance of steady body physiology is highly significant because any type of disturbance in the homeostasis can leads various physiological abnormalities.
Various membrane transport process such as osmosis helps in the movement of water from high concentration region to the region of low water concentration until equilibrium is reached.Thus osmosis helps to maintain water homeostasis in our body.
By the same way glucose transporter maintain the homeostasis of glucose inside our body.
When we breathe, our respiratory system takes up oxygen and carbon dioxide or other useless gases go out . The oxygen combines with the haemoglobin in the blood of the circulatory system . This is transferred to all the cells of our body to get energy.
Answer:
Vestigial organs are a type of homologous organs.
Explanation:
Vestigial organs are rudimentary in present organisms. Vestigial organs such as wisdom teeth,nictating membrane of eyes,body hairs,which were functional organs in ancestors. Though they are present in an organism in reduced form but are functionless.
Examples of vestigial organs:
1. Human tail or appendix,
2. Pelvic bone of a snake
3. Wings of flightless birds
4.Male breast tissues and nipples
All the members of a specific species that live in an area are a population.
