Answer:
C) Hair is different from kidneys because the cells that make up hair and kidneys have different genes.
Explanation:
Answer:
chloroplasts
Explanation:
chloroplasts contain chlorophyll which is responsible for making photosynthesis possible.
Answer:
- Radial symmetry is advantageous because sessile animals can "sit down", take food, or sense harmful environmental conditions from different directions.
- Bilateral symmetry allows motile animals to move straight forward.
- The major evolutionary advantages of bilateral symmetry include cephalization, the formation of a head and tail area and a more directional motion.
Explanation:
Radial symmetry is advantageous for sessile organisms since it enables the uniform distribution of the sensory receptors around the body. In consequence, sessile organisms can react to environmental stimuli from every direction. On the other hand, bilateral symmetry allows motile organisms the arrangement of a specialized nervous system from the anterior end of the organism (i.e., the 'head'). Moreover, another important advantage of bilateral symmetry is the ability to equalize environmental pressures on both sides of the body, thereby enabling a rectilinear motion.
Answer:
A. The gene for insulin is located on chromosome 11 in all people.
Explanation:
Genomics includes the study of the content, organization, function and evolution of genetic information in a complete genome. The genomic term is relatively recent. It is considered that it was coined by Thomas Roderick, in 1986, to refer to the subdiscipline of genetics dedicated to the study of cartography, sequencing and analysis of the functions of complete genomes.
Insulin is formed as pre-proinsulin of the precursor protein. This is encoded by a 14kb series in the INS gene. In most animals including humans, a single gene for insulin is found. The human gene is located on the short arm of chromosome 11 at position 15.5 (11p15.5).
The insulin gene has recently been decoded in its complete form in genomic studies. The human and rat insulin genes have been reproduced and the DNA has been sorted. It has been shown that mouse and rat insulins are identical and have similar gene series and organization, which are similar in genetic series to humans.
