I believe the correct answer is mRNA. Dicer is a part of RNase III which leaves double stranded RNA and pre-microRNA into short double stranded RNA fragments called small interfering RNA and microRNA respectively. The Dicer facilitates the activation of RNA induced silencing complex (RISC), which are essential for RNA interference. The RISC has a catalytic component argonate, which is an endonuclease capable of degrading mRNA. siRNAs are specfic to the mRNA sequence unlike miRNAs which are not completely complementary to the mRNA sequence.
B is correct. A tendon will join a muscle to a bone, and a ligament joins a bone to another bone. I think of it this way, partly influenced by my biology teacher:
- The achilles tendon, at the back of your foot, clearly joins foot to calf muscle
- The word ligament comes from 'deligare' in Latin, which roughly means to tie together. A ligament 'ties' two bones together
I hope this helps
The answer is C I don’t think this needs more explanation but if needed just ask!
Where you able to find the answer
Answer:
mitosis, cell growth, and differentiation
Explanation:
There are several ways through which plants grow which may include the process of mitosis mainly that involves cell division. The increase in height in plants is attributed to not only cell division but also growth of the newly formed cell.
Mitosis involved division of cell and in cell growth, cells increase their size that ultimately cause growth of plant height. The highly active growth cells are meristem cells that are found at tips of the plants. They are actively dividing zones of plants and with their division and growth plant increases their heights.
Another mechanism, responsible for increase in height is cell differentiation. Differentiation is the process during which cells are specialized to perform specialized function. For example: Xylem are specialized for transport of water. Phloem are specialized for the transport of food. Similarly, some cells are specialized for growth and they are aimed at increasing in size and division that ultimately increase the plant height.
So, mitosis, cell growth, and differentiation are the mechanisms, that increase plant height due to changes in specialized regions of cells in the tips of their branches.
