Osteoarthritis is a wear and tear type of arthritis often affects aging population affecting joints in hands,knees and lower back. Heberden's node is an example and develops around middle age thus Wendell might have this.
Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
Answer:
a. Excretion is accomplished by paired protonephridia with flame cells in every segment of the body. True
Most anelids have structures called metanephrids or protonephridia. Both structures are homologous to the kidneys and have the function of excresion, A pair are present in every segment of the body.
b. If the organs in one segment fail, the organs of another segment will still function. False
It is false because all segments are interrelated and have different functions depending on their location.For example, the first segment is where the sensory appendages are, such as the antennae and the eyes. The second segment is where the mouth is. There are a series of parapod segments to move, collectively called metameres and ends in a terminal portion called pigidium, where the anus is located.
c. Annelids possess both circular and longitudinal muscles that produce waves of contraction that are propagated down through the points eBookseries of segments.True
True because anelids have circular and longitudinal muscles that serve to function the hydrostatic skeleton.
d. Segmentation has allowed for specialization in the anterior of the annelid body, which has provided for a more sophisticated nervous system. True
True because the segmentation allows to have a nervous system formed by a ventral nerve cord provided with ganglia and lateral nerves in each segment.
"D: A new gene, which codes for the protein that can repair defective genes, is introduced."
Explanation: <span>Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery.</span>
