Answer:
DNA was discovered in 1869 by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells (white blood cells). Instead, he isolated a new molecule he called nuclein (DNA with associated proteins) from a cell nucleus.
Explanation:
Answer:
The organisms homeostasis
Answer:
Ecological competition occurs when living organisms, including animals, plants, bacteria and fungi, need the same limited resources to thrive in their shared environment. An ecosystem could collapse if several species needed the same scarce resources to complete their life cycle. Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.

The question is incomplete. The complete question is as follows:
Functions of astrocytes include all of the following, except
A) performing repairs in damaged neural tissue.
B) guiding neuron development.
C) functioning in action potential transmission.
D) maintaining the blood-brain barrier.
E) creating a three-dimensional framework for the CNS.
Answer:
Functioning in action potential transmission.
Explanation:
Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.
Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.
Thus, the correct answer is option (c).
