Answer:
into the cell from the solution causing it to expand
Explanation:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. Diagram of red blood cells in hypertonic solution (shriveled), isotonic solution (normal), and hypotonic solution (puffed up and bursting).
Answer:
C) esophagus - moves air from the nose into the lungs
Explanation:
The oesophagus is a muscular tube with a sphincter valve at each end. Its main function is to transport food and fluid, after being swallowed, from the mouth to the stomach.This is propelled from the pharynx into the oesophagus, and towards the stomach in a peristaltic waves. The peristalsis also pushes food along the alimentary canal
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
Answer:
the two organelles found only in plants include chloroplasts and cell wall.
Explanation:
cell wall is the outermost boundary in most plant cells while animal cells lack it .but the cell wall of plant cells is different from that of prokaryotic cell wall, both in structure and chemical composition.CELL WALL prevents the osmotic lysis of plants and provides them a definite shape. another organelle found only in plants is the CHLOROPLAST. choloroplasts are the type of plastids which are not found in animal cells .choloroplast contain a green pigment called chlorophyll which halp in PHOTOSYNTHESIS. in adition to these plants also contain GLYOXYSOMES and a large "centeral" vacuole which is present in animal cells but it is of small size and pushed towards periphery due to nucleus.
