Answer:
Answer is 2. Fibroblasts fail to divide.
Explanation:
Tissue culture experiment is the experiment where tissues are grown in an artificial medium. This involves the use of growth medium such as agar or broth. This process help to produce needed tissues in a short period of time.
Fibroblasts are cells which are found in the collective tissues, and they produce collagen. The collagen produced by the Fibroblasts play important role in tissue repair. Fibroblasts are regarded as the main cells in the connective tissue.
Note that, PDGF, which is Platelet -derived growth factor in full, is a growth factor regulating cell growth and it's division.
Answer:
In mosses gamete are produced by MITOSIS; In ferns gametes are produced by MITOSIS.
Explanation:
Ferns usually grow way bigger than mosses and they are both primitive plants. In ferns the gametes, sperm and eggs are formed by mitosis when there is a suitable place for development.
The idea it can describe is that it is the transfer of information from one neuron to another.
<h3>Transfer of information </h3>
The nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.
The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.
The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.

This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
