Answer;
B) all levels of organization within an organism are interdependent.
Explanation;
-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
The levels of organization are dependent on each other, for example, the organ systems rely on each other for many different things and cannot function without the other. e.g. The nervous and endocrine systems control the activities of the digestive, excretory, circulatory and respiratory systems. Organ systems need to work together to maintain homeostasis in the body.
Answer:
depolarization leading to action potentials
Explanation:
The voltage-gated Na+ channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na+ channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.
DNA and Histones Form bread-like globules known as nucleotides
Answer:
Yes, man has been curious about the world and his existence since the beginning, Due to this curiosity, man has always tried to solve the mystery of life. With the passage of time, the observation and discoveries of man led him to reach to all the modern advances which can be seen today in the world. Today, man has a better knowledge about his existence and the existence of life on Earth. Although a lot has yet to be discovered but we have been able to solve a lot of the mystery of the earth.
