The magnetic fields are strongest at point A and weakest at point C. The magnetic field lines can be used to indicate the strength of a magnet or magnetic field. The closer together the magnetic field lines the stronger the magnetic field.
Explanation:
The magnetic field line also shows the direction of the magnetic field, hence they are also considered vector fields because they have magnitude and direction. They usually have an arrow indicating that the field lines are moving from the north pole to the south pole. The lines also never cross and are always in closed loops.

<span>When there is the presence of gills it will be easy to determine if the animal is aquatic or mollusk.
Aquatic means related to water. While Mollusca is termed as the large phylum of invertebrate animals whose members are called mollusks. Most of the mollusks live in water.
The most numerous mollusks are mantle which is important for cavity and is used for excretion and breathing, the presence of radula and their structure of the nervous system.</span>
Answer: C.) Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.
Explanation:
Phylogeny is the evolutionary science which derives a relationship among the ancient species with their descendants based upon common genetic, physiological and morphological characteristics. Cladistics represent the study of a group of organisms which exhibit a common ancestor. A clade includes organisms having a common ancestors and exhibit similar traits in them. A clade is sufficient to include the organisms in a phylogenic tree based upon their evolutionary history.

What is a winter storm watch?
A Winter Storm Watch is issued by the National Weather Service of the United States when there is a potential for heavy snow or significant ice accumulations.
The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
