Both A, B, and C are found in the excretory system.
Myofibrils are in the muscle of the intestines, villi increase surface area of the intestine, and nephrons help to filter in the kidney. Osteoblasts are found in bone, so therefore is not part of the excretory system
Answer:
Extensive damage to oligodendrocytes in the cns could result in l<u>oss of sensation and motor control.</u>
Explanation:
Oligodendrocytes are presnt in glial cells of Central nervous System which comprises of Brain and spinal cord.They are related to the nerve cells. It provides support by production of glial cell line derived neutrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) or insulin growth factor IGF-1 they reduce ion leakage and decrease the capacitance of the cell membrane. Due to intensive damage of the Oligodendrocytes the motor nerves and other nerves of CNS damages looses it activity.
These are mainly occurred due to peripheral injury or demylinated diseases like multiple sclerosis, leukodystrophies,cerebral plasy and other congential disorders.Some chemicals like fluorouracil causes damage to the oligodendrocytes.
Answer:
3' to 5'; 5' to 3'
Explanation:
The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA. The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.
Answer:
Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
