Answer:
<h2>c. Migration distance on a gel is inversely proportional to DNA fragment size </h2>
Explanation:
- Deoxyribonucleic acid is a genetic material that is a type of macromolecule.
- It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group.
- Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role.
- Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size.
- So the migration distance is inversely proportional to the DNA fragment size.
Answer:
The correct answer is A. The two cerebral hemispheres are separated by the longitudinal fissure.
Explanation:
The longitudinal or intercerebral fissure is a deep cleft that divides the brain longitudinally into two hemispheres (the right and the left) joined together by the corpus callosum. Other fissures, such as the central sulcus, the lateral sulcus and the internal perpendicular fissure, divide each hemisphere into large cerebral lobes, which in turn have cerebral convolutions.
Destruction of the forest results in the disappearance of the species in this forest, which might not be found in other forests. This means that some species will become extinct. Extinction of species leads to reduction of biodiversity - the correct answer is the first one: forest destruction will <span> reduce biodiversity and remove organisms with the potential to help humans</span>
Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve. Involuntary reflex reaction to exposure or inexposure to light—in low light conditions a dilated pupil lets more light into the eye. :)
