Myelin sheaths are found on the outside of nerve cells. They protect the sensitive axons underneath like how insulation protects wires.
Answer:
The answer is Option B the nucleus
Explanation:
Genetic information in prokaryotic cells is carried on a single circular piece of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no enclosing membrane, so there is no true nucleus, but simply a concentration of DNA known as a nucleoid.
and DNA is present in the nucleus. Therefore option B is correct

Nutrients including sulfur and Phosphorus move through the ecosystem through a biogeochemical cyclic process. Chemical elements move via a pathway, that is termed as a biogeochemical cycle. Those move by means of the biotic and the abiotic components of the ecosystem.

Answer:
Dominant sporophyte generation and microscopic gametophyte within sporophyte.
Explanation:
The sporophyte is the dominant generation, but multicellular male and female gametophytes which are microscopic in nature with the female gametophyte made up of few cells being buried in the tissues of the sporophyte and the male gametophyte, the pollen grain, being carried from plant to plant by wind, water, or animals. these are all produced within the flowers of the sporophyte.
Answer:
In the clarification section elsewhere here, the definition of the concern is mentioned.
Explanation:
- The notion of fitness seems to be the basic phenomenon of Fisher. Fitness is a dynamic term since it is the calculation by a person in his lifetime of the cumulative production of viable progeny. The fitness of an organism is zero even though no offspring is created. With a growing life span as well as the amount of order to promote innovation, flexibility increases. Members of an organization that are very well-adapted to that certain range of environmental factors have had a benefit in the mechanism of selective breeding over others who might not be as possibly the best adapted. The benefit falls throughout the form of genetic diversity and longevity.
- Those people who are much more able to easily find and use food supplies, for example, would live considerably longer and have more offspring than someone who is less reliable at seeking food. Inherited features that increase human fitness are then passed on to their descendants, thereby providing this very same value to the descendants.
- The disappearance of fewer adapted varieties seems to be the most drastic alternative. Unless the best-adapted variant doesn't adjust even though it is as when the optimum balanced local, so for the ideal characteristic, less drastic will delete both-new variant.
- Since less drastic selection has become too inadequate to aggressive edge mutations, the aggregation of missense mutations will happen and even the outcome would be a progressive deterioration of genomic integrity. If it maintains you prolonged enough, this should contribute to disappearance for certain species; nevertheless, the subsequent widespread presence of the deleterious mutations just seems like such a genome would then inevitably also contribute to backward mutation incidence. Extinction could result if the intense choice has become too high for the entire world, because if the world is saved in time.
