The production of sperm and egg cells are an indication that meiosis took place in the life cycle of a jellyfish. Gametes, or sex cells are produced in meiosis. Another indication is based on the legend in the phase 1 arrow, is haploid. The result of meiosis is also haploid, while in mitosis it is diploid.
Multipotent cell
is a kind of atem cell that can only develop into cells that are closely related to the original stem cell.
<u>Explanation:</u>
Our body contains stem cells which help to regenerate or repair a particular cell or tissue during the time of need. There are different types of stem cells which provide as a life saver to the individuals to recreate the tampered organ or tissue.
The multipotent cells unlike other stem cells have specific functions only. They can develop into cells that are closely related to the original stem cell. On stimuli a multipotent blood stem cell can give rice to related cells but cannot produce a neuron or other kind of cells. Hence multipotent cells are mainly used in transplantation.
Answer:
The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.
Explanation:
Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.
The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).
This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.
- The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
- CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.
Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.
